The arbuscular mycorrhizal symbiosis: a molecular review of the fungal dimension. (1/560)

Mycorrhizal associations vary widely in structure and function, but the most common interaction is the arbuscular mycorrhizal (AM) symbiosis. This interaction is formed between the roots of over 80% of all terrestrial plant species and Zygomycete fungi from the Order Glomales. These fungi are termed AM fungi and are obligate symbionts which form endomycorrhizal symbioses. This symbiosis confers benefits directly to the host plant's growth and development through the acquisition of P and other mineral nutrients from the soil by the fungus. In addition, they may also enhance the plant's resistance to biotic and abiotic stresses. These beneficial effects of the AM symbiosis occur as a result of a complex molecular dialogue between the two symbiotic partners. Identifying the molecules involved in the dialogue is a prerequisite for a greater understanding of the symbiosis. Ongoing research attempts to understand the underlying dialogue and concomitant molecular changes occurring in the plant and the fungus during the establishment of a functioning AM symbiosis. This paper focuses on the molecular approaches being used to study AM fungal genes being expressed in the symbiotic and asymbiotic stages of its lifecycle. In addition, the importance of studying these fungi, in relation to understanding plant processes, is discussed briefly.  (+info)

The indolic compound hypaphorine produced by ectomycorrhizal fungus interferes with auxin action and evokes early responses in nonhost Arabidopsis thaliana. (3/560)

Signals leading to mycorrhizal differentiation are largely unknown. We have studied the sensitivity of the root system from plant model Arabidopsis thaliana to hypaphorine, the major indolic compound isolated from the basidiomycetous fungus Pisolithus tinctorius. This fungi establishes ectomycorrhizas with Eucalyptus globulus. Hypaphorine controls root hair elongation and counteracts the activity of indole-3-acetic acid on root elongation on A. thaliana, as previously reported for the host plant. In addition, we show that hypaphorine counteracts the rapid upregulation by indole-3-acetic acid and 1-naphthalenic-acetic acid of the primary auxin-responsive gene IAA1 and induces a rapid, transient membrane depolarization in root hairs and suspension cells, due to the modulation of anion and K+ currents. These early responses indicate that components necessary for symbiosis-related differentiation events are present in the nonhost plant A. thaliana and provide tools for the dissection of the hypaphorine-auxin interaction.  (+info)

A phosphate transporter from Medicago truncatula involved in the acquisition of phosphate released by arbuscular mycorrhizal fungi. (4/560)

Many plants have the capacity to obtain phosphate via a symbiotic association with arbuscular mycorrhizal (AM) fungi. In AM associations, the fungi release phosphate from differentiated hyphae called arbuscules, that develop within the cortical cells, and the plant transports the phosphate across a symbiotic membrane, called the periarbuscular membrane, into the cortical cell. In Medicago truncatula, a model legume used widely for studies of root symbioses, it is apparent that the phosphate transporters known to operate at the root-soil interface do not participate in symbiotic phosphate transport. EST database searches with short sequence motifs shared by known phosphate transporters enabled the identification of a novel phosphate transporter from M. truncatula, MtPT4. MtPT4 is significantly different from the plant root phosphate transporters cloned to date. Complementation of yeast phosphate transport mutants indicated that MtPT4 functions as a phosphate transporter, and estimates of the K(m) suggest a relatively low affinity for phosphate. MtPT4 is expressed only in mycorrhizal roots, and the MtPT4 promoter directs expression exclusively in cells containing arbuscules. MtPT4 is located in the membrane fraction of mycorrhizal roots, and immunolocalization revealed that MtPT4 colocalizes with the arbuscules, consistent with a location on the periarbuscular membrane. The transport properties and spatial expression patterns of MtPT4 are consistent with a role in the acquisition of phosphate released by the fungus in the AM symbiosis.  (+info)

Genetic and cytogenetic mapping of DMI1, DMI2, and DMI3 genes of Medicago truncatula involved in Nod factor transduction, nodulation, and mycorrhization. (5/560)

The DMI1, DMI2, and DMI3 genes of Medicago truncatula, which are required for both nodulation and mycorrhization, control early steps of Nod factor signal transduction. Here, we have used diverse approaches to pave the way for the map-based cloning of these genes. Molecular amplification fragment length polymorphism markers linked to the three genes were identified by bulked segregant analysis. Integration of these markers into the general genetic map of M. truncatula revealed that DMI1, DMI2, and DMI3 are located on linkage groups 2, 5, and 8, respectively. Cytogenetic studies using fluorescent in situ hybridization (FISH) on mitotic and pachytene chromosomes confirmed the location of DMI1, DMI2, and DMI3 on chromosomes 2, 5, and 8. FISH-pachytene studies revealed that the three genes are in euchromatic regions of the genome, with a ratio of genetic to cytogenetic distances between 0.8 and 1.6 cM per microm in the DMI1, DMI2, and DMI3 regions. Through grafting experiments, we showed that the genetic control of the dmi1, dmi2, and dmi3 nodulation phenotypes is determined at the root level. This means that mutants can be transformed by Agrobacterium rhizogenes to accelerate the complementation step of map-based cloning projects for DMI1, DMI2, and DMI3.  (+info)

Phosphorus effects on metabolic processes in monoxenic arbuscular mycorrhiza cultures. (6/560)

The influence of external phosphorus (P) on carbon (C) allocation and metabolism as well as processes related to P metabolism was studied in monoxenic arbuscular mycorrhiza cultures of carrot (Daucus carota). Fungal hyphae of Glomus intraradices proliferated from the solid minimal medium containing the colonized roots into C-free liquid minimal medium with different P treatments. The fungus formed around three times higher biomass in P-free liquid medium than in medium with 2.5 mM inorganic P (high-P). Mycelium in the second experiment was harvested at an earlier growth stage to study metabolic processes when the mycelium was actively growing. P treatment influenced the root P content and [(13)C]glucose administered to the roots 7 d before harvest gave a negative correlation between root P content and (13)C enrichment in arbuscular mycorrhiza fungal storage lipids in the extraradical hyphae. Eighteen percent of the enriched (13)C in extraradical hyphae was recovered in the fatty acid 16:1omega5 from neutral lipids. Polyphosphate accumulated in hyphae even in P-free medium. No influence of P treatment on fungal acid phosphatase activity was observed, whereas the proportion of alkaline-phosphatase-active hyphae was highest in high-P medium. We demonstrated the presence of a motile tubular vacuolar system in G. intraradices. This system was rarely seen in hyphae subjected to the highest P treatment. We concluded that the direct responses of the extraradical hyphae to the P concentration in the medium are limited. The effects found in hyphae seemed instead to be related to increased availability of P to the host root.  (+info)

Induction of jasmonate biosynthesis in arbuscular mycorrhizal barley roots. (7/560)

Colonization of barley (Hordeum vulgare cv Salome) roots by an arbuscular mycorrhizal fungus, Glomus intraradices Schenck & Smith, leads to elevated levels of endogenous jasmonic acid (JA) and its amino acid conjugate JA-isoleucine, whereas the level of the JA precursor, oxophytodienoic acid, remains constant. The rise in jasmonates is accompanied by the expression of genes coding for an enzyme of JA biosynthesis (allene oxide synthase) and of a jasmonate-induced protein (JIP23). In situ hybridization and immunocytochemical analysis revealed that expression of these genes occurred cell specifically within arbuscule-containing root cortex cells. The concomitant gene expression indicates that jasmonates are generated and act within arbuscule-containing cells. By use of a near-synchronous mycorrhization, analysis of temporal expression patterns showed the occurrence of transcript accumulation 4 to 6 d after the appearance of the first arbuscules. This suggests that the endogenous rise in jasmonates might be related to the fully established symbiosis rather than to the recognition of interacting partners or to the onset of interaction. Because the plant supplies the fungus with carbohydrates, a model is proposed in which the induction of JA biosynthesis in colonized roots is linked to the stronger sink function of mycorrhizal roots compared with nonmycorrhizal roots.  (+info)

Exploring root symbiotic programs in the model legume Medicago truncatula using EST analysis. (8/560)

We report on a large-scale expressed sequence tag (EST) sequencing and analysis program aimed at characterizing the sets of genes expressed in roots of the model legume Medicago truncatula during interactions with either of two microsymbionts, the nitrogen-fixing bacterium Sinorhizobium meliloti or the arbuscular mycorrhizal fungus Glomus intraradices. We have designed specific tools for in silico analysis of EST data, in relation to chimeric cDNA detection, EST clustering, encoded protein prediction, and detection of differential expression. Our 21 473 5'- and 3'-ESTs could be grouped into 6359 EST clusters, corresponding to distinct virtual genes, along with 52 498 other M.truncatula ESTs available in the dbEST (NCBI) database that were recruited in the process. These clusters were manually annotated, using a specifically developed annotation interface. Analysis of EST cluster distribution in various M.truncatula cDNA libraries, supported by a refined R test to evaluate statistical significance and by 'electronic northern' representation, enabled us to identify a large number of novel genes predicted to be up- or down-regulated during either symbiotic root interaction. These in silico analyses provide a first global view of the genetic programs for root symbioses in M.truncatula. A searchable database has been built and can be accessed through a public interface.  (+info)

Arbuscular mycorrhizas (AMs), formed between AM fungi and vascular plants, are a widespread mutualistic symbiosis where fungi colonize root cells, transfer mineral nutrients (mainly phosphate) and, in turn, obtain carbon of a photosynthetic origin. To explore the possible roles played by antioxidant enzymes in the roots and shoots of AM-inoculated potato cultivars, a field experiment was conducted using three potato cultivars (Agria, Santé and Arinda) and two Glomus intraradices levels (0 and 30 g). The leaf and root activities of catalase (CAT), peroxidase (POX) and ascorbate peroxidase (APX) affecting mycorrhizal colonization and potato yield were measured. Under AM inoculation, the three CAT, POX and APX enzymes were induced in both the roots and leaves of all the cultivars. However, the highest increases in POX, APX and CAT activities under AM inoculation were noted in the leaves of Santé and the roots of Arinda. Mycorrhizal colonization was more pronounced under arbuscular mycorrhiza ...

Arbuscular mycorrhizal fungi (AMF) are obligate biotrophs; nevertheless their spores can germinate in the absence of host plants. Such inconsistent behavior is balanced by diverse survival strategies. The ability of AM fungal hyphae to fuse might represent a fundamental survival strategy because germlings could plug into compatible mycorrhizal networks, thus gaining access to plant-derived carbon before asymbiotic growth arrest. An in vivo experimental system was used to grow extraradical mycelium produced by Glomus mosseae colonizing three different plant species and germlings of the same isolate. After symbiotic and asymbiotic mycelia came into contact we showed that germling hyphae fused with symbiotic network hyphae and established protoplasm connections with nuclei occurring in fusion bridges. The frequency of anastomoses between germling and symbiotic hyphae was 4.9-23.9%. Prefusion and postfusion incompatible responses, with protoplasm withdrawal in interacting hyphae, were evident in ...

Arbuscular mycorrhizal fungi (AMF) play vital roles in sustaining soil productivity and plant communities. However, adaption and differentiation of AMF in response to commonly used fertilization remain poorly understood. In this study, we showed that the AMF community composition was primarily driven by soil physiochemical changes associated with chronic inorganic and organic fertilization of 37 years in Mollisols. High-throughput sequencing indicated that inorganic fertilizer negatively affected AMF diversity and richness, implying a reduction of mutualism in plant-AMF symbiosis; however, a reverse trend was observed for the application of inorganic fertilizer combined with manure. With regards to AMF community composition, order Glomerales was dominant, but varied significantly among different fertilization treatments. All fertilization treatments decreased family Glomeraceae and genus Funneliformis, while Rhizophagus abundance increased. Plant-growth-promoting-microorganisms of family
Soil microorganisms play an important role in enhancing soil fertility and plant health. Arbuscular mycorrhizal fungi and plant growth promoting rhizobacteria form a key component of the soil microbial population. Arbuscular mycorrhizal fungi form symbiotic association with most of the cultivated crop plants and they help plants in phosphorus nutrition and protecting them against biotic and abiotic stresses. Many species of Bacillus occurring in soil are also known to promote plant growth through phosphate solubilization, phytohormone production and protection against biotic and abiotic stresses. Synergistic interaction between AMF and Bacillus spp. in promoting plant growth compared to single inoculation with either of them has been reported. This is because of enhanced nutrient uptake, protection against plant pathogens and alleviation of abiotic stresses (water, salinity and heavy metal) through dual inoculation compared to inoculation with either AMF or Bacillus alone.

Arbuscular mycorrhiza (AM) is a root endosymbiosis between plants and glomeromycete fungi. It is the most widespread terrestrial plant symbiosis, improving plant uptake of water and mineral nutrients. Yet, despite its crucial role in land ecosystems, molecular mechanisms leading to its formation are just beginning to be unravelled. Recent evidence suggests that AM fungi produce diffusible symbiotic signals. Here we show that Glomus intraradices secretes symbiotic signals that are a mixture of sulphated and non-sulphated simple lipochitooligosaccharides (LCOs), which stimulate formation of AM in plant species of diverse families (Fabaceae, Asteraceae and Umbelliferae). In the legume Medicago truncatula these signals stimulate root growth and branching by the symbiotic DMI signalling pathway. These findings provide a better understanding of the evolution of signalling mechanisms involved in plant root endosymbioses and will greatly facilitate their molecular dissection. They also open the way to using
A fungus root or mycorrhiza (plural: mycorrhizae) is a fungus living in a mutually beneficial symbiosis (or mutualism) with the roots of a vascular plant. In this intimate relationship, the fungus benefits from access to energy-containing carbohydrates, proteins, and other organic nutrients excreted by, or contained in, the roots while the host plant benefits from an enhanced supply of inorganic nutrients, especially phosphorus.. The fungi carry out this function largely by increasing the rate of decomposition of organic matter in the immediate vicinity of the plant root, and by efficiently absorbing the inorganic nutrients that are liberated by this process. From the perspective of the plant, the most important of the mineral nutrients supplied by the fungus are compounds of phosphorus, and to a lesser degree, of nitrogen.. Mycorrhizae are a common type of mutualism; about 90% of the families of vascular plants live in this sort of beneficial relationship with fungi. Only a few economically ...
An assay based on the competitive polymerase chain reaction (PCR) was developed to quantify Glomus mosseae, an arbuscular mycorrhizal (AM) fungus, within plant roots. Using previously designed G. mosseae specific primers, a heterologous internal standard was constructed by amplifying Pseudomonas DNA under low stringency annealing conditions. Go-amplification of G. mosseae and internal standard DNA within leek root extracts provided accurate quantification of target DNA. Colonization of leek roots by G. mosseae was monitored in a comparative study by competitive PCR and microscopy, a conventional method of quantification. These two methods gave closely parallel data for G. mosseae colonization from three different inoculum levels over a 6 week period Results indicate that competitive PCR is a sensitive and accurate method of quantification. The major advantage of competitive PCR over microscopy is that it can quantify specific AM fungi. ...
The mycorrhizal symbiosis between soil fungi and plant roots is a ubiquitous mutualism that plays key roles in plant nutrition, soil health, and carbon cycling. The symbiosis evolved repeatedly and independently as multiple morphotypes [e.g., arbuscular mycorrhizae (AM), ectomycorrhizal (ECM)] in multiple fungal clades (e.g., phyla Glomeromycota, Ascomycota, Basidiomycota). The accessibility and cultivability of many mycorrhizal partners make them ideal models for symbiosis studies. Alongside molecular, physiological, and ecological investigations, sequencing led to the first three mycorrhizal fungal genomes, representing two morphotypes and three phyla. The genome of the ECM basidiomycete Laccaria bicolor showed that the mycorrhizal lifestyle can evolve through loss of plant cell wall-degrading enzymes (PCWDEs) and expansion of lineage-specific gene families such as short secreted protein (SSP) effectors. The genome of the ECM ascomycete Tuber melanosporum showed that the ECM type can evolve ...
Previous studies have found that some phosphate (Pi) starvation inducible transporter genes are downregulated and arbuscular mycorrhizal (AM) inducible Pi transporter genes are upregulated in maize roots associated with the fungus Glomus intraradices. However, little is known about the functional diversity of different AM fungal species in influencing the expression of Pi transporters in maize roots. Here, we studied the expression of two Pi transporter genes ZEAma:Pht1;3 (Pi starvation inducible) and ZEAma:Pht1;6 (AM inducible) in maize root colonized by different AM fungal inoculants. Non-mycorrhizal maize, maize colonized by Glomus deserticola (CA113), Glomus intraradices (IA506), Glomus mosseae (CA201), Gigaspora gigantea (MN922A) and the co-inoculation of all four species were established. The expression patterns of the two genes were quantified using real-time, reverse transcription polymerase chain reaction. The expression level of ZEAma:Pht1;6 was 26-135 times higher in AM plants than in non
An ectomycorrhiza (from Greek ἐκτός ektos, outside, μύκης mykes, fungus, and ῥίζα rhiza, root; pl. ectomycorrhizas or ectomycorrhizae, abbreviated EcM) is a form of symbiotic relationship that occurs between a fungal symbiont and the roots of various plant species. The mycobiont tends to be predominantly from the phyla Basidiomycota and Ascomycota, although a few are represented in the phylum Zygomycota. Ectomycorrhizas form between fungi and the roots of around 2% of plant species. These tend to be composed of woody plants, including species from the birch, dipterocarp, myrtle, beech, willow, pine and rose families. Unlike other mycorrhizal relationships, such as arbuscular mycorrhiza and ericoid mycorrhiza, ectomycorrhizal fungi do not penetrate their hosts cell walls. Instead, they form an entirely intercellular interface, consisting of highly branched hyphae forming a latticework between epidermal and cortical root cells, known as the Hartig net. Ectomycorrhizas are ...
The occurrence of arbuscular mycorrhizal fungi (AMF) was assessed by both morphological and molecular criteria in two salt marshes: (i) a NaCl site of the island Terschelling, Atlantic Coast, the Netherlands and (ii) a K2CO3 marsh at Schreyahn, Northern Germany. The overall biodiversity of AMF, based on sequence analysis, was comparably low in roots at both sites. However, the morphological spore analyses from soil samples of both sites exhibited a higher AMF biodiversity. Glomus geosporum was the only fungus of the Glomerales that was detected both as spores in soil samples and in roots of the AMF-colonized salt plants Aster tripolium and Puccinellia sp. at both saline sites and on all sampling dates (one exception). In roots, sequences of Glomus intraradices prevailed, but this fungus could not be identified unambiguously from DNA of soil spores. Likewise, Glomus sp. uncultured, only deposited as sequence in the database, was widely detected by DNA sequencing in root samples. All attempts to ...
ecosystem as a whole as it helps to maintain ecological stability and evolution [6]. There exists a general lack of specificity between plants and fungi which suggests that plant species that share compatible mycorrhizal fungi lead to the building of plant communication communities [6]. Ecosystems that facilitate this symbiotic relationship between plant and fungi include temperate and boreal forests, woodlands, grasslands, Arctic tundra, woodland savannah, Mediterranean and Sclerophyllous woodlands, and tropical forests and woodlands [6]. The colonization of mycorrhizal networks is dependent upon soil environmental factors, alternate hosts, host plant stress, carbon allocation patterns, fungal genotype, plant genotype, and interactions between microbial communities in the soil [6]. The most important factor in the functioning of the mycorrhiza networks is the allocation of carbon from host plants. Fueled by carbon, the mycorrhizal networks power to act as avenues for the transfer of nutrients ...
Most mycorrhizal fungi fall into two broad categories:. Ectomycorrhizal Fungi - These fungi are often specific in the plants they associate with and include many of the commonly wild-harvested mushrooms (e.g. Chanterelles, Boletes, Matsutake, and Russula species). They form complex multi-species relationships that are somewhat difficult to reproduce commerically. As such, these mycorrhizal fungi are not commonly cultivated.. Endomycorrhizal Fungi - Also known as Arbuscular Mycorrhizae (AM), these fungi include all the Glomeromycota species. These species are generalists, meaning that they can associate with many different plant species. One mycelial network of an endomycorrhizal fungus can be associated with numerous plants of various species and genera. Thus, these fungi literally connect the plants of the forest (or garden) together and channel resources among them. These fungi build soil structure and porosity through the creation of a sticky protein called glomalin, which is what ...
p,Plants and mycorrhizal fungi form a mutualism in which plants donate carbon to the fungus and, in return, receive benefits such as increased nutrient uptake and water. Mycorrhizal fungi colonize plant roots, forming nutrient exchange structures. The fungi also colonize the soil by growing long strands of hyphae that forage for nutrients and attach plants, forming a common mycorrhizal network (CMN). Plants attached to a well-supported CMN will receive greater benefits than those attached to a lesser CMN because the more carbon donations the fungal partner receives, the more it can grow and colonize the soil, accessing hard to reach soil nutrients. Kin selection theory predicts that relatives should donate more carbon to the fungal partner than non-relatives because benefits gained by neighbouring relatives through the CMN lead to inclusive fitness gains. Thus, social environment, i.e. relatedness of the group, could affect the mycorrhizal mutualism. Moreover, the presence of mycorrhizal fungi ...
1. Plants allocate substantial amounts of carbon (C) below‐ground to obtain nutrients and other resources. 2. Increasing nutrient availability typically reduces the C investment in root growth and mycorrhizal fungi, hence reducing the C cost of nutrient acquisition. This C cost of nutrient acquisition, however, remains poorly quantified. 3. In a P fertilization experiment with Zea mays, we examined below‐ground C allocation and the C cost of phosphorus (P) uptake. In addition, we compared plants inoculated with arbuscular mycorrhizal fungi (AMF) to those growing in pasteurized soil to examine the same measures in the absence of AMF. 4. P fertilization tended to increase above‐ground plant growth more than it increased the total below‐ground C flux (TBCF; root growth plus rhizosphere respiration), suggesting a reduced investment in nutrient acquisition. This was confirmed by a negative fertilization effect on the TBCF‐to‐total plant P ratio (~25% reduction for high vs. low P ...
Maize plants are well colonized with arbuscular mycorrhizal fungi (AMF), which contribute mineral nutrients absorption from soil. However little is known about their role in nitrogen (N) absorption especially from amino acids, which reach a considerable quantity in soils. This experiment was conducted to investigate N acquisition from amino acids through AMF symbiosis. AMF inoculation clearly increased the N content of maize supplied with amino acids (Glu, Ala and Pro). Further study of xylem sap revealed that the composition of amino acids was changed by AMF inoculation. These results indicate that AMF contribute N from amino acids, and may affect the nitrogen assimilation of host plants.
A major limitation to plant growth is the restricted access to nutrients in the soil. To improve nutrient acquisition, the majority of land plants enter a beneficial symbiosis with arbuscular mycorrhizal (AM) fungi. The accommodation of fungal hyphae in roots requires the extensive transcriptional reprogramming of host cells. Several GRASdomain proteins, including NSP1 (NODULATION SIGNALLING PATHWAY 1), NSP2, and RAM1 (REQUIRED FOR ARBUSCULAR MYCORRHIZATION 1), have emerged as important transcriptional regulators during mycorrhization. Interaction studies suggest that these proteins form multicomponent complexes, raising the question whether they regulate similar or different mycorrhizal processes. Here, the functions of NSP1, NSP2 and RAM1 during AM development were investigated by detailed phenotypic and transcriptional analyses of the corresponding loss‐of‐function mutants. Global gene expression profiling of nsp1‐1 revealed that NSP1 is required for the expression of a large number of ...
Arbuscular mycorrhizal fungi (AMF) are soil fungi forming symbiotic associations with majority of land plants. AMF alter soil organic matter (SOM) directly through stabilization of soil aggregates and indirectly providing a path in which plant fixed C02 is transferred below-ground. Understanding contributions of AMF to SOM via protein production and stabilization of soil aggregates will greatly aid our understanding of soil carbon sequestration, nutrient cycling and mitigation of soil erosion. The work presented in chapter 2 challenges the glomalin extraction process and assesses the accuracy of the Bradford and monoclonal-antibody ELISA detection methods. My results clarify the contribution of glomalin to SOM: suggesting the extraction process is not eliminating all non-glomalin proteins. My results indicate that the Bradford is prone to overestimating the presence of glomalin when soils contain large concentrations of SOM, the ELISA is prone to retention and interference biases depending on the amount

Maintaining the levels of nitrogen in agricultural fields to ensure crop yield performance is challenging due to the complex dynamics of nitrogen transformation in soil. Nitrogen is mainly taken up by plant roots in the form of nitrate, but it is considered as an environmental pollutant that threatens human and animal health. Therefore, it is necessary to use adsorbent compounds to retain nitrate in the soil. The effectiveness of two types of biochar produced from rice husk (Br) and populous wood (Bp) and two arbuscular mycorrhizal fungi, namely Funneliformis intraradices (Mi) and Funneliformis versiforme (Mv), on nitrate leaching in soil was evaluated. The soil columns planted with corn were filled with an artificial sandy clay loam soil fertigated with urea fertilizer under glasshouse conditions . After nine weeks of growing the plants, a pulse of nitrogen (0.48 g urea per core) was added to the columns. One week after the addition of urea, the shoots of the plants were removed, and the columns

Arbuscular mycorrhizal fungi (AMF) are obligate root symbionts that can protect their host plant against biotic stress factors such as plant-parasitic nematode (PPN) infection. PPN consist of a wide range of species with different life styles that can cause major damage in many important crops worldwide. Various mechanisms have been proposed to play a role in the biocontrol effect of AMF against PPN. This review presents an overview of the different mechanisms that have been proposed, and discusses into more detail the plausibility of their involvement in the biocontrol against PPN specifically. The proposed mechanisms include enhanced plant tolerance, direct competition for nutrients and space, induced systemic resistance (ISR) and altered rhizosphere interactions. Recent studies have emphasized the importance of ISR in biocontrol and are increasingly placing rhizosphere effects on the foreground as well, both of which will be the focal point of this review. Though AMF are not yet widely used ...
The large subunit of the mitochondrial ribosomal RNA genes (mtLSU) has previously been identified as a highly sensitive molecular marker for intraspecies diversity in the arbuscular mycorrhizal fungus Glomus intraradices. In this study, the respective region was analyzed in five species of Glomus (G. mosseae, G. geosporum, G. caledonium, G. clarum, G. coronatum) from the same major clade (Glomus group A), Glomus sp. ISCB 34 from the related Glomus group B and two species of Scutellospora. Results show low level of genetic polymorphism between related morphospecies. Introns homologous to those found in G. intraradices were detected as well as new ones, some of them containing putative ORFs for homing endonucleases (HEs). Introns without ORFs for HEs seem to have been inherited strictly vertically from the ancestors of Glomus groups A and B while other introns indicate occasional horizontal transfer and possibly maintenance, degeneration and loss together with their associated HE ORFs. Overall, we provide
This study aimed to evaluate the impact of genetically modified (GM) wheat with introduced pm3b mildew resistance transgene, on two types of root-colonizing microorganisms, namely pseudomonads and arbuscular mycorrhizal fungi (AMF). Our investigations were carried out in field trials over three field seasons and at two locations. Serial dilution in selective Kings B medium and microscopy were used to assess the abundance of cultivable pseudomonads and AMF, respectively. We developed a denaturing gradient gel electrophoresis (DGGE) method to characterize the diversity of the pqqC gene, which is involved in Pseudomonas phosphate solubilization. A major result was that in the first field season Pseudomonas abundances and diversity on roots of GM pm3b lines, but also on non-GM sister lines were different from those of the parental lines and conventional wheat cultivars. This indicates a strong effect of the procedures by which these plants were created, as GM and sister lines were generated via tissue

Mycorrhizal fungi are critical members of the plant microbiome, forming a symbiosis with the roots of most plants on Earth. Most plant species partner with either arbuscular or ectomycorrhizal fungi, and these symbioses are thought to represent plant adaptations to fast and slow soil nutrient cycling rates. This generates a second hypothesis, that arbuscular and ectomycorrhizal plant species traits complement and reinforce these fungal strategies, resulting in nutrient acquisitive vs. conservative plant trait profiles. Here we analyzed 17,764 species level trait observations from 2,940 woody plant species to show that mycorrhizal plants differ systematically in nitrogen and phosphorus economic traits. Differences were clearest in temperate latitudes, where ectomycorrhizal plant species are more nitrogen use- and phosphorus use-conservative than arbuscular mycorrhizal species. This difference is reflected in both aboveground and belowground plant traits and is robust to controlling for ...

La micoriza arbuscular (en anglès: arbuscular mycorrhiza en plural mycorrhizae o mycorrhizas, dit també AM Fungi, també anomenada endomicoriza) és un tipus de fong micoriza que penetra en les cèl·lules corticals de les arrels duna planta vascular.. Les micorizes arbusculars (AMs) es caracteritzen per la formació duna estructura especial com els arbúsculs i les vesícules per fongs del fílum Glomeromycota (fongs AM ). Els fongs AM (AMF) ajuden les plantes a capturar nutrients com el fòsfor, sofre, nitrogen i micronutrients del sòl. Es creu que el desenvolupament dels fongs micorizes van jugar un paper important en la colonització inicial de la Terra per les plantes i en levolució de les plantes vascular.[1]. Sha dit que és més fàcil donar una llista de les plantes que no formen micorices arbusculars que no pas de les que les formen.[2] Aquesta simbiosi és una relació altament desenvolupada entre els fongs i les plantes i la relació simbiòtica més estesa.[3] lAM es troba ...

The word mycorrhizae comes from the Greek words for fungus and root, and refers to the symbiotic relationship that exists between plant roots and certain fungi. In natural settings, these mycorrhizal fungi are present in the soil in association with plant roots. The fungi colonize by attaching to the surface of the root (ectomycorrhizal) or to the inside of the root cells (endomycorrhizal). Then they send their filaments (called mycelium) into the surrounding soil, effectively extending the plants roots and root absorbing capacity ten to 1000 times-far beyond what the plant can do alone.3 Several miles of these ultra-fine filaments can be present in less than a thimbleful of soil. Mycorrhizae supply the water and nutrients needed by the plant for establishment and survival, and, in return, receive from the plant roots sugars and other compounds needed by the fungus. Mycorrhizae are much smaller than roots, so they can easily penetrate into smaller spaces between soil particles, where they ...
Approximately 90% of all plant species are associated with fungal species forming mutually beneficial mycorrhizal relationships. It has been well documented that mycorrhizal fungi improve plant growth, health and tolerance to adverse growing conditions such as acid soils, drought and heavy metals. Mycorrhizal fungi are an essential component of the soil ecosystem and provide an intimate link with both crop and indigenous plants. Several different mycorrhizal types are found and are broadly divided into endomycorrhizas and ectomycorrhizas (ECM).. Arbuscular mycorrhizas (AM) are the most common group of the endomycorrhizas forming a unique morphology within the root cortex. These fungi are classified under the Glomeromycota and associate with a wide variety of crop and herbaceous plants. The ECM on the other hand are more restricted forming an association with tree species such as Pines, Eucalyptus and Oaks. The fungal partners are generally members of the Basidiomycotina with some Ascomycotina ...
Plant growth in acidic soils is limited by low levels of available phosphorus (P) and the high presence of phytotoxic aluminum (Al3+), which causes deleterious effects on plant physiology and growth (Fageria and Baligar, 2008). There are several mechanisms to alter the chemical form and toxicity of Al in the environment and/or function within plant cells to reduce the negative effects of Al on plant metabolism (Kochian et al., 2004). In this sense, sufficient genetic variation in Al-tolerance has been reported among wheat cultivars (Raman et al., 2005; Liu et al., 2015). In relation to the alleviation of these abiotic stresses is where the AM association plays an important role in acid soils, through the interaction Al-P in colonized roots (Marschner, 1995), an improvement of nutrient absorption (Borie and Rubio, 1999; Lux and Cumming, 2001; Cornejo et al., 2008; Barea, 2015) or through kidnapping the Al by an enhancement of root organic acid excretion (Klugh-Stewart and Cumming, 2009) and ...

Cheatgrass (Bromus tectorum L.) is a highly invasive winter annual grass that has caused significant changes to the steppe ecosystem of western North America. Cheatgrass is considered a facultative host of arbuscular mycorrhizal fungi (AMF), and has been shown to reduce AMF density in invaded soils and reduce AMF diversity in roots of neighboring grasses. However, specific information about interactions between cheatgrass and AMF remains unknown, as well as how these interactions differ from native vegetation. The research presented here addresses these knowledge gaps. To determine when cheatgrass is colonized by AMF and the magnitude of colonization, two dense cheatgrass patches were identified in invaded shortgrass prairie in Colorado. Individuals were excavated every three weeks, from six weeks after germination through senescence. Roots were collected from individuals, cleared, stained, and observed for AMF colonization. Roots were colonized by AMF at every sampling date, but percent ...
Lotus japonicus THIC is expressed in all organs, and the encoded protein catalyzes thiamine biosynthesis. Loss of function produces chlorosis, a typical thiamine-deficiency phenotype, and mortality. To investigate thiamines role in symbiosis, we focused on THI1, a thiamine-biosynthesis gene expressed in roots, nodules, and seeds. The thi1 mutant had green leaves, but formed small nodules and immature seeds. These phenotypes were rescued by THI1 complementation and by exogenous thiamine. Thus, THI1 is required for nodule enlargement and seed maturation. On the other hand, colonization by arbuscular mycorrhiza (AM) fungus Rhizophagus irregularis was not affected in the thi1 mutant or by exogenous thiamine. However, spores of R. irregularis stored more thiamine than the source (host plants), despite lacking thiamine biosynthesis genes. Therefore, disturbance of the thiamine supply would affect progeny phenotypes such as spore formation and hyphal growth. Further investigation will be required to ...
Although arbuscular mycorrhizal (AM) fungi are a major pathway in the global carbon cycle, their basic biology and, in particular, their respiratory response to temperature remain obscure. • A pulse label of the stable isotope 13C was applied to Plantago lanceolata, either uninoculated or inoculated with the AM fungus Glomus mosseae. The extra-radical mycelium (ERM) of the fungus was allowed to grow into a separate hyphal compartment excluding roots. We determined the carbon costs of the ERM and tested for a direct temperature effect on its respiration by measuring total carbon and the 13C:12C ratio of respired CO2. With a second pulse we tested for acclimation of ERM respiration after 2 wk of soil warming. • Root colonization remained unchanged between the two pulses but warming the hyphal compartment increased ERM length. δ13C signals peaked within the first 10 h and were higher in mycorrhizal treatments. The concentration of CO2 in the gas samples fluctuated diurnally and was highest in ...

Arbuscular mycorrhizal fungi (AMF) can stimulate the plant growth. Pseudomonas sp. (KCIGC01) NBRC109613 isolated from the spores of Glomus clarum IK97, an AMF, is reported to support the plant growth and development as partner bacteria (PB) for AMF REF _Ref399417929 \r \h \* MERGEFORMAT [1]. In order to investigate the effect of G. clarum IK97 and Pseudomonas sp. (KCIGC01) NBRC109613 on the secondary metabolites, these microorganisms were inoculated to sesame plants. The inoculation of these microorganisms stimulated the growth of sesame. The rate of sesame root colonization in G. clarum IK97 + Pseudomonas sp. (KCIGC01) NBRC109613 inoculated plants (66.4% ± 4.4%) was higher than that in G. clarum IK97 alone inoculated plants (39.2% ± 5.8%). Furthermore, the content of sesamin in sesame seeds was increased by the inoculation of these microorganisms. In particular, the content of sesamin in the treatment inoculated with G. clarum IK97 and Pseudomonas sp. (KCIGC01) NBRC-109613 was 11.4 ± 1.5 mg
Strawberry is an important fruit crop within the UK. To reduce the impact of soil-borne diseases and extend the production season, more than half of the UK strawberry production is now in substrate (predominantly coir) under protection. Substrates such as coir are usually depleted of microbes including arbuscular mycorrhizal fungi (AMF) and consequently the introduction of beneficial microbes is likely to benefit commercial cropping systems. Inoculating strawberry plants in substrate other than coir has been shown to increase plants tolerance to soil-borne pathogens and water stress. We carried out studies to investigate whether AMF could improve strawberry production in coir under low nitrogen input and regulated deficit irrigation. Application of AMF led to an appreciable increase in the size and number of class I fruit, especially under either deficient irrigation or low nitrogen input condition. However, root length colonization by AMF was reduced in strawberry grown in coir compared to soil and

Productivity, enzymatic activity and physiological effects in peanut plants associated with arbuscular mycorrhizal fungus and supplemented with seaweed extract
Soil salinization and the associated land degradation are major and growing ecological problems. Excess salt in soil impedes plant photosynthetic processes and root uptake of water and nutrients such as K+. Arbuscular mycorrhizal (AM) fungi can mitigate salt stress in host plants. Although numerous studies demonstrate that photosynthesis and water status are improved by mycorrhizae, the molecular mechanisms involved have received little research attention. In the present study, we analyzed the effects of AM symbiosis and salt stress on photosynthesis, water status, concentrations of Na+ and K+, and the expression of several genes associated with photosynthesis (RppsbA, RppsbD, RprbcL and RprbcS) and genes coding for aquaporins or membrane transport proteins involved in K+ and/or Na+ uptake, translocation or compartmentalization homeostasis (RpSOS1, RpHKT1, RpNHX1 and RpSKOR) in black locust. The results showed that salinity reduced the net photosynthetic rate, stomatal conductance and relative water
In the State of Amazonas there are two distinct periods of rainfall distribution, which are concentrated between December and April and a dry period, which runs from June to September. This climate characteristic can interfere in the establishment of the mycorrhizal association in forest species, considering that soil moisture can interfere with the germination of mycorrhizal fungi spores. The soil moisture near the field capacity favors the development of symbiosis, and alternations between dry and rainy periods can favor the sporulation of AMF. However, there are discrepancies among the studies regarding the establishment of mycorrhizal fungi as a function of soil moisture. The restriction of water availability in the months of low precipitation induces in the microorganisms associated with the plant, the activation of adaptation mechanisms, such as increased sporulation. The mycorrhization occurs mainly in thin and new roots, which must be present at the time the AMF are observed, a situation that
Comparable sweet orange seedlings were grown in soilless medium and either were inoculated with the vesicular-arbuscular mycorrhizal fungus Glomus intraradices (VAM) or were nonmycorrhizal and fertilized with soluble P (NM). Seedlings, 8 or 10 mo old, were transplanted into a low P (3.5 g/g) citrus soil that was noninfested or infested with 1 or 10 chlamydospores of Phytophthora parasitica per cubic centimeter of soil. In one experiment, root dry weight and leaf P content of noninfested VAM seedlings were greater than those of NM plants, which were nearly deficient in P. P. parasitica reduced leaf P status of VAM and NM seedlings alike but reduced dry weight of only VAM plants. There were significantly fewer rotted root tips on VAM seedlings. P. parasitica reduced VAM colonization as a result of the loss of root tips. In a second experiment, at the higher inoculum density of P. parasitica, NM and VAM seedlings were similar in size and had sufficient levels of leaf P. P. parasitica infestation ...
We studied the influence of inoculation with a mixture of three exotic arbuscular mycorrhizal (AM) fungi, Glomus intraradices Schenck & Smith, Glomus deserticola Trappe, Bloss. & Menge and Glomus mosseae (Nicol & Gerd.) Gerd. & Trappe, and the addition of composted sewage sludge (SS) on the activities of the antioxidant enzymes superoxide dismutase (SOD, EC 1.15.1.1) and total peroxidase (POX) and of shoot and root nitrate reductase (NR, EC 1.6.6.1) in Juniperus oxycedrus L. seedlings, an evergreen shrub, grown in a non-sterile soil under well-watered and drought-stress conditions. Both the inoculation with exotic AM fungi and the addition of composted SS stimulated significantly growth and the N and P contents in shoot tissues of J. oxycedrus with respect to the plants neither inoculated nor treated with composted SS that were either well-watered or droughted. Under drought-stress conditions, only inoculation with exotic AM fungi increased shoot and root NR activity (about 188% and 38%, ...

Ectomycorrhizas, or EcM, are typically formed between the roots of around 10% of plant families, mostly woody plants including the birch, dipterocarp, eucalyptus, oak, pine, and rose[22] families and fungi belonging to the Basidiomycota, Ascomycota, and Zygomycota. Some EcM fungi, such as many Leccinum and Suillus, are symbiotic with only one particular genus of plant, while other fungi, such as the Amanita, are generalists that form mycorrhizas with many different plants.[28] An individual tree may have 15 or more different fungal EcM partners at one time.[29] Thousands of ectomycorrhizal fungal species exist, hosted in over 200 genera. A recent study has permitted to conservatively estimate global ectomycorrhizal fungal species richness around 7750 species, although, on the basis of estimates of knowns and unknowns in macromycete diversity, a final estimate of ECM species richness would likely be between 20000 and 25000.[30]. Ectomycorrhizas consist of a hyphal sheath, or mantle, covering the ...
Topic: Mycorrhizal Fungi. Speaker: Jeremiah A. Henning. Although they are an invisible group of soil-dwelling organisms, mycorrhizal fungi are critical to the maintenance of plant diversity, plant productivity, and the storage of carbon in soils. Mycorrhizal fungi likely hold the key to how ecosystems will respond to global change. For my talk, I will introduce the audience to the group of fungi I study, Glomeromycota, then briefly introduce a couple of the classic studies demonstrating the important links between fungal diversity, plant diversity, productivity, and soil carbon. Once I lay this ground work, I will transition into how these fungi may shape ecosystem response to global change, talking very generally about the carbon cycle and a few of my past and current research projects.. I am currently a post-doctoral researcher associate in the department Ecology, Evolution, and Behavior at the University of Minnesota. I recently relocated back to the midwest after completing my PhD at the ...
ARTEAGA-LEON, Cristina et al. Ectomycorrhizal inoculation with edible fungi increases plant growth and nutrient contents of Pinus ayacahuite. Rev. Mex. Biodiv. [online]. 2018, vol.89, n.4, pp.1089-1099. ISSN 2007-8706. https://doi.org/10.22201/ib.20078706e.2018.4.2235.. The international trade of natural Christmas trees generates billions of US dollars annually; the production of such trees in Mexico is a growing industry, delivering around 900,000 trees annually, mainly from the native species Pinus ayacahuite. To survive, this species establishes a mutualistic symbiosis in its roots known as ectomycorrhiza. However, currently no studies have been performed regarding the ectomycorrhizal inoculation effects on P. ayacahuite. In this work, the effect of ectomycorrhizal inoculation on the growth and nutritional content of P. ayacahuite was evaluated using 2 native edible ectomycorrhizal mushrooms. After 2 years, the inoculation produced increases of total dry weight and total contents of macro- ...

Nonsterile peat was used as substrate. Five different fungal isolates growing in symbiosis with pine seedlings were investigated: two isolates of Paxillus involutus, one of Suillus bovinus and two unidentified ectomycorrhizal fungi isolated from ectomycorrhizal root tips. Three different nitrogen sources were used: ammonium as (NH4)2SO4, nitrate as NaNO3 and a complete nutrient solution (Ingestad 1979), and three different nitrogen concentrations, 1, 2 or 4 mg N/g dry wt. of peat. The mycelial growth of all fungi was found to be negatively affected by the nitrogen amendments, although the sensitivity to nitrogen varied between the isolates. One of the unidentified isolates was extremely sensitive and growth was completely inhibited by all nitrogen treatments. In contrast, the growth of one of the P. ...

Xtreme Gardening Mykos Granular - 2.2lb Mykos Pure, Fresh Alive: A beneficial organism, Mycorrhiza, plural Mycorrhizae live on the roots of plants and form a symbiotic relationship. They extend microscopic straw-like filaments called hyphae into the soil where they extract, transport, and dramatically increase a host plant s supply of nutrients and moisture. Pockets of nutrients and water in the soil which were once unreachable by standard root systems are now made accessible through the super-mining effects which mycorrhiza gifts to your plants. Mycorrhiza also releases a glue-like substance into the soil (Glomalin) which improves water storage and capacity, leading to lower watering costs. Although ideal for use on all plants, mycorrhizae is especially beneficial toward: Tomatoes, Herbs (Thyme, Basil, Sage, ect), Pumpkins, Beans, Bulbs (all), Squash, Cantaloupe, Carrot, Celery, Corn, Cucumber, Garlic, Leek, Lettuce, Melon, Onion, Peas, Potato, Strawberry, and Grape Varietals.

The structure of the charcoal provide a refuge for small beneficial soil organisms from large grazers like earthworms.. Charcoal increases activity by mycorhizal fungi. It doesnt appear that this effect changes with the manufacturing temperature of the charcoal.. There is a long tradition in Japan of using charcoal as a soil improver. Nishio (1996) states the idea that the application of charcoal stimulates indigenous arbuscular mycorrhiza fungi in soil and thus promotes plant growth is relatively well-known in Japan, although the actual application of charcoal is limited due to its high cost. The relationship between mycorrhizal fungi and charcoal may be important in realising the potential of charcoal to improve fertility. Nishio (1996) reports that charcoal was found to be ineffective at stimulating alfalfa growth when added to sterilised soil, but that alfalfa growth was increased by a factor of 1.7-1.8 when unsterilised soil containing native mycorrizal fungi was also added.

COVACEVICH, Fernanda; CASTELLARI, Claudia C y ECHEVERRIA, Hernán E. Physical and chemical methods for eliminating propagules of indigenous mycorrhizal fungi from soil samples. Rev. argent. microbiol. [online]. 2014, vol.46, n.3, pp.231-236. ISSN 0325-7541.. The objective of this work was to evaluate methods to eliminate or reduce the number of indigenous arbuscular mycorrhizal fungi (AMF) from soil samples without affecting their edaphic or microbiological properties. At an early trial we evaluated moist heat (autoclaving), dry heat (oven), sodium hypochlorite (NaClO) and formaldehyde at a range of 100.0-3.3 µl/g and 16.7-3.3 µl/g respectively. There was no germination in plants of ryegrass (Lolium multiflorum Lam.) sown on substrates receiving NaClO (100.0-33.3 ul/g), whereas autoclaving significantly increased the available soil phosphorous content. Both treatments failed to eradicate AMF colonization at 9 weeks; therefore, they were discarded. In a second trial, oven and formaldehyde (10.0 ...

The role of microorganism is very critical in nutrient management of horticulture and plantation forestry. They are conductors of the nutrient management orchestra as they provide by inputs in terms of micro and macronutrients besides organic matter and can be called as bio-inoculants (biofertilizers). Biofertilizers play a vital role in fixing the atmospheric nitrogen and mobilization of phosphorous, sulfur, manganese, copper, and iron in the soil. Symbiotic (Rhizobium and Frankia) and nonsymbiotic microorganisms (Azospirillum) are known to improve the soil fertility by fixing the atmospheric nitrogen. Arbuscular mycorrhizae fungi (AM fungi) and phosphobacterium have ability to transfer insoluble phosphate into soluble form. Moving in this direction it becomes imperative to understand as forest microbiologist and pathologist, the roles played by microorganism in diverse plants-soil-microbe interaction to analyze their effectiveness in improving their efficiency. Biofertilizers are economy and
Salt stress is an important environmental stress. Plants cope with salt stress with different strategies. In this study the effects of 2 different arbuscular mycorrhiza species (Glomus mosseae and G. intraradices) on some biochemical parameters in pepper plants (Capsicum annuum L. cv. Cumaovasi) exposed to long term salt stress were studied. It was found that mycorrhizal inoculation increased RWC, P, total chlorophyll, and carotenoid content of pepper plants during salt application. The enzyme activities changed depending on the enzyme and salt stress application. The lowest MDA content was found in the plants inoculated with G. intraradices; however, there was no significant difference between the NaCl applications. It was found that plants inoculated with G. intraradices had less lipid peroxidation, and therefore it can be said that these plants have an advantage under salt stress ...
In the low Si soil AM fungi increased root Si concentrations and reduced root herbivore performance. Both commercial and native AM treatments increased root Si and also reduced root herbivore growth rates by 107% and 81%, respectively. AM colonisation positively correlated with root Si concentrations. Distinct from this, in the high Si soil AM fungi had no impact on root Si or root herbivore growth. However, root consumption was reduced; a response independent of Si concentrations.. ...

In a greenhouse experiment, the effects of Glomus intraradices and indigenous mycorrhizal isolates from soils under plow and no-till treatments on the uptake of 32P placed at 1, 2.5 and 4 cm from the roots of white clover (Trifolium repens) in 23, 37 or 46 days after planting were compared.Spores of the indigenous fungi were mostly a mixture of Glomus mossea, G. clarum, G. caledonium and G. claroideum . The colonization of the roots with regard to hyphae, vesicle or arbuscules was significantly different among fungi. Uptake of 32P from different distances from the roots was strongly dependent on the mycorrhizal isolate used and the plant-symbiont age. Indigenous fungi were more effective in translocating 32P from short distances compared with G. intraradices as measured in the plants. At the age of 46 days, for example, fungi from no-till and plowed plots transported 8-10 times more 32P to the plants as compared with G. intraradices, when32P was placed at 1-cm distance from the roots.

In general, plant root zone expansion is a highly desirable outcome for any cultural or product-based aspect of crop production. Roots are a plants lifeline to water and nutrients that directly affect productivity. MycoApply® biorational soil health products, based on a four-species consortium of beneficial arbuscular mycorrhizal fungi (AMF), achieve this goal by expanding the plants absorption area through branching AMF filaments, or hyphae, that extend well beyond the reach of the roots. Studies show mycorrhizae expand root absorption area by up to 50x.. In stone fruit, newly planted transplant establsishment is essential to increase the return on investment of new plantings. MycoApply helps establish new trees, especially weak cultivars and rootstocks, into production sooner as well as an increased survival rate. Established stone fruit trees benefit from symbiosis relationships with mycorrhizal fungi for nutrient and water absorption as root systems become less efficient. As a result of ...

Arbuscular mycorrhizae are associations between fungi and the roots of vascular plants. Part of this dissertation is devoted to analyzing the fatty acid and sterols of mycorrhizal and non-mycorrhizal Sorghum with the aim of identifying universal molecular markers of mycorrhizal infection. The mycorrhizal fungi contain high amounts of unusual lipids that may be used to mark their presence in infected roots. My results show that phosopholipid fatty acid 16:1, as well as campesterol are molecules that can be used to consistently identify mycorrhizal infection. In addition, lipid profiles may provide insight as to which fungal species is present in the roots.. In a second experiment, the fatty acids and sterols of several isolates of root pathogenic fungi were surveyed to assess the taxonomic value of lipid profiles. My results show that the genera Rhizoctonia and Pythium can be reliably identified because of their characteristic lipid composition.. Another question that I address in this work is: ...
Les champignons mycorhiziens à arbuscules (CMA), classés dans le phylum Glomeromycota, ne peuvent pas être facilement identifiés par la morphologie de leurs spores et leurs mycélia à lintérieur ou à lextérieur des racines de leurs hôtes. Ce problème fondamental didentification rend létude de leur diversité, en particulier dans leur habitat naturel (sol et racine) extrêmement difficile. Les gènes ribosomaux ont été largement utilisés pour développer des amorces spécifiques et en inférer des arbres phylogénétiques. Cependant, ces gènes sont très polymorphes et existent en plusieurs copies dans le génome des CMA, ce qui complique linterprétation des résultats. Dans notre étude, nous avons étudié le polymorphisme intra- et inter-spécifique du gène β-tubuline, présent en faible nombre de copies dans le génome des CMA, afin dobtenir de nouvelles séquences nucléotidiques pour développer des marqueurs moléculaires. Les gènes β-tubuline amplifiés à partir ...

Incorporation of organic amendments (OA) into phosphorus (P) management plans can have beneficial effects on arbuscular mycorrhizas (AM). OA alone may not be able to meet crop P demands.Combined use of OA and mineral P fertilisers successfully met crop P demands.Bicarbonate-extractable P gives a good indication of the P fertiliser potential of OA.

A survey of VA Mycorrhizal fungi in the root zone of some pulses was carried out . The pulses selected for VAM survey were Cow Pea (Vigna anguiculata L.) , green gram ( Vigna radiates L. ), black gram ( Vigna mungo L.) and Chick pea ( Cicer arietinum L.). Random soil samples and roots were collected after every 30 days and VA Mycorrhizal spores isolated . The spores were identified up to species level based on the revised synoptic key by Berch and Trappe(1989). This study reports the extent of root colonization and the density and distribution of VAM spores in the rhizosphere and non-rhizosphere soil. All the pulses examined invariably showed a high percentage (55% - 80%) of root colonization .Species of Acaulospora , Glomus , Gigaspora, Sclerocystis and scutilospora were isolated. The spore density ranged from 30 - 90 spores /25 g soil. The intensity of root colonization and spore density varied not only from genus to genus with in a family but also for the same plant species at

The presence of fungal symbionts residing in the root tissue of plants is a well-documented occurrence, yet questions regarding the identification and comparison of fungal partners in mycorrhizal relationships have been largely unanswered. Ericoid mycorrhizae, an example of a mycorrhizal relationship, are found in host plants within the order Ericales. Ericales, which contains such familiar species as persimmon, blueberry and Rhododendron, are able to persist in edaphic conditions due to their fungal symbionts. These symbionts form hyphal coils inside plant cell membranes, and thereby exchange crucial nutrients with the host plant. This project aims to evaluate the specificity between fungal communities and their host Rhododendron species, with the expectation that differing communities may exist, even in closely related hosts. Using known techniques to extract fungal DNA from the root systems of Rhododendron species in varying conditions and proximity, this DNA is then used to generate species ...

Regulatory networks controling the initiation and development of an arbuscular mycorrhiza (AM) symbiosis involve the interaction of different classes of transcription factors (TFs), primarily belonging to the NF-Y, GRAS, AP2/ERF, and Myb categories. To identify protein-protein interactions amongst selected, AM-activated TFs as well as between those TFs and their target promoters, yeast-2-hybrid (Y2H) and yeast-1-hybrid (Y1H) experiments are performed. To verify such protein-protein interactions in planta, split-YFP fusions of selected, AM-activated TFs are expressed in transgenic Medicago truncatula roots or Nicotiana benthamiana leaves.. ...
