Identification of Epichloe endophytes in planta by a microsatellite-based PCR fingerprinting assay with automated analysis. (1/2575)

Epichloe endophytes are a group of filamentous fungi that include both sexual (Epichloe) and asexual (Neotyphodium) species. As a group they are genetically diverse and form both antagonistic and mutualistic associations with temperate grasses. We report here on the development of a microsatellite-based PCR system for fingerprinting this group of fungi with template isolated from either culture or infected plant material. M13mp19 partial genomic libraries were constructed for size-fractionated genomic DNA from two endophyte strains. These libraries were screened with a mixture of DIG-labeled dinucleotide and trinucleotide repeat probes. Positive clones were sequenced, and nine unique microsatellite loci were identified. An additional microsatellite was serendipitously identified in the 3' untranscribed region of the 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase gene from N. lolii Lp19. Primers were designed for each locus and a panel of endophytes, from different taxonomic groupings, was screened to determine the degree of polymorphism. On the basis of these results a multiplex assay was developed for strain identification with fluorescently labeled primers for five of these loci. Using this system the size of the products amplified can be precisely determined by automated analysis, and an allele profile for each strain can be readily generated. The assay was shown to resolve endophyte groupings to the level of known isozyme phenotype groupings. In a blind test the assay was used successfully to identify a set of endophytes in planta. A reference database of allele sizes has been established for the panel of endophytes examined, and this will be expanded as new strains are analyzed.  (+info)

Beauveriolides, specific inhibitors of lipid droplet formation in mouse macrophages, produced by Beauveria sp. FO-6979. (2/2575)

Beauveria sp. FO-6979, a soil isolate, was found to produce inhibitors of lipid droplet formation in mouse peritoneal macrophages. A new compound beauveriolide III was isolated along with a known compound beauveriolide I from the fermentation broth of the producing strain by solvent extraction, ODS column chromatography, silica gel column chromatography and preparative HPLC. Beauveriolides I and III caused a reduction in the number and size of cytosolic lipid droplets in macrophages at 10 microM without any cytotoxic effect on macrophages.  (+info)

Physiological consequence of disruption of the VMA1 gene in the riboflavin overproducer Ashbya gossypii. (3/2575)

The vacuolar ATPase subunit A structural gene VMA1 of the biotechnologically important riboflavin overproducer Ashbya gossypii was cloned and disrupted to prevent riboflavin retention in the vacuolar compartment and to redirect the riboflavin flux into the medium. Cloning was achieved by polymerase chain reaction using oligonucleotide primers derived form conserved sequences of the Vma1 proteins from yeast and filamentous fungi. The deduced polypeptide comprises 617 amino acids with a calculated molecular mass of 67.8 kDa. The deduced amino acid sequence is highly similar to that of the catalytic subunits of Saccharomyces cerevisiae (67 kDa), Candida tropicalis (67 kDa), and Neurospora crassa (67 kDa) with 89, 87, and 60% identity, respectively, and shows about 25% identity to the beta-subunit of the FoF1-ATPase of S. cerevisiae and Schizosaccharomyces pombe. In contrast to S. cerevisiae, however, where disruption of the VMA1 gene was conditionally lethal, and to N. crassa, where viable disruptants could not be isolated, disruption of the VMA1 gene in A. gossypii did not cause a lethal phenotype. Disruption of the AgVMA1 gene led to complete excretion of riboflavin into the medium instead of retention in the vacuolar compartment, as observed in the wild type.  (+info)

Properties of a subtilisin-like proteinase from a psychrotrophic Vibrio species comparison with proteinase K and aqualysin I. (4/2575)

An extracellular serine proteinase purified from cultures of a psychrotrophic Vibrio species (strain PA-44) belongs to the proteinase K family of the superfamily of subtilisin-like proteinases. The enzyme is secreted as a 47-kDa protein, but under mild heat treatment (30 min at 40 degrees C) undergoes autoproteolytic cleavage on the carboxyl-side of the molecule to give a proteinase with a molecular mass of about 36 kDa that apparently shares most of the enzymatic characteristics and the stability of the 47-kDa protein. In this study, selected enzymatic properties of the Vibrio proteinase were compared with those of the related proteinases, proteinase K and aqualysin I, as representative mesophilic and thermophilic enzymes, respectively. The catalytic efficiency (kcat/Km) for the amidase activity of the cold-adapted enzyme against succinyl-AAPF-p-nitroanilide was significantly higher than that of its mesophilic and thermophilic counterparts, especially when compared with aqualysin I. The stability of the Vibrio proteinase, both towards heat and denaturants, was found to be significantly lower than of either proteinase K or aqualysin I. One or more disulfide bonds in the psychrotrophic proteinase are important for the integrity of the active enzyme structure, as disulfide cleavage, either by reduction with dithiothreitol or by sulfitolysis, led to a loss in its activity. Under the same conditions, aqualysin I was also partially inactivated by dithiothreitol, but the activity of proteinase K was unaffected. The disulfides of either proteinase K or aqualysin I were not reactive towards sulfitolysis, except under denaturing conditions, while all disulfides of the Vibrio proteinase reacted in absence of a denaturant. The reactivity of the disulfides of the proteins as a function of denaturant concentration followed the order: Vibrio proteinase > proteinase K > aqualysin I. The same order of reactivity was also observed for the inactivation of the enzymes by H2O2-oxidation, as a function of temperature. The order of reactivity observed in these reactions most likely reflects the accessibility of the reactive cystine or methionine side chains present in the three related proteinases, and hence a difference in the compactness of their protein structures.  (+info)

A function for the plasmalemma grooves of a fission yeast. (5/2575)

Ultrastructural studies on regenerating protoplasts of Schizosaccharomyces pombe show that the spatial differentiation of the plasmalemma into grooves and flat areas is reflected in a functional differentiation in cell-wall synthesis. The grooves are the initial site of production of wall fibrils.  (+info)

The phenoloxidases of the ascomycete Podospora anserina. Structural differences between laccases of high and low molecular weight. (6/2575)

In order to investigate the extent of the relationship between the three copper-containing glycoproteins, laccases I, II and III (Mr70000, 80000 and 390000 respectively) of Podospora anserina, the following experiments were carried out on laccases II and III: (a) determination of amino acid composition; (b) determination of N-terminal and C-terminal amino acid; (c) determination of sugar composition; (d) dissociation studies on native and denatured laccases and also after removal of copper from the enzymes; (e) digestion of the carbohydrate moieties with the aid of glycosylhydrolases. A comparison between the results of these experiments and data previously obtained with laccase I allows the following conclusions to be drawn. 1. Laccases II and III are not identical. 2. Neither of these low molecular weight laccases are as complete molecules subunits of the oligomeric laccase I. 3. The possibility of partial identity of amino acid sequences of laccases I and III can not be excluded. 4. Laccase II possibly consists of subunits of Mr37000 whereas laccase III does not. 5. Digestion of 50% of the carbohydrate content leads to complete loss of serological specificity (serological reaction and cross reaction). This finding is discussed with regard to the possible role of the carbohydrate moiety as antigenic determinants and thus as the reason for the immunological relationship. As a consequence, at least three independent structural genes for laccases must be assumed.  (+info)

Discovery of a small molecule insulin mimetic with antidiabetic activity in mice. (7/2575)

Insulin elicits a spectrum of biological responses by binding to its cell surface receptor. In a screen for small molecules that activate the human insulin receptor tyrosine kinase, a nonpeptidyl fungal metabolite (L-783,281) was identified that acted as an insulin mimetic in several biochemical and cellular assays. The compound was selective for insulin receptor versus insulin-like growth factor I (IGFI) receptor and other receptor tyrosine kinases. Oral administration of L-783,281 to two mouse models of diabetes resulted in significant lowering in blood glucose levels. These results demonstrate the feasibility of discovering novel insulin receptor activators that may lead to new therapies for diabetes.  (+info)

Multiple mitochondrial viruses in an isolate of the Dutch Elm disease fungus Ophiostoma novo-ulmi. (8/2575)

The nucleotide sequences of three mitochondrial virus double-stranded (ds) RNAs, RNA-4 (2599 nucleotides), RNA-5 (2474 nucleotides), and RNA-6 (2343 nucleotides), in a diseased isolate Log1/3-8d2 (Ld) of the Dutch elm disease fungus Ophiostoma novo-ulmi have been determined. All these RNAs are A-U-rich (71-73% A + U residues). Using the fungal mitochondrial genetic code in which UGA codes for tryptophan, the positive-strand of each of RNAs 4, 5, and 6 contains a single open reading frame (ORF) with the potential to encode a protein of 783, 729, and 695 amino acids, respectively, all of which contain conserved motifs characteristic of RNA-dependent RNA polymerases (RdRps). Sequence comparisons showed that these RNAs are related to each other and to a previously characterized RNA, RNA-3a, from the same O. novo-ulmi isolate, especially within the RdRp-like motifs. However, the overall RNA nucleotide and RdRp amino acid sequence identities were relatively low (43-55% and 20-32%, respectively). The 5'- and 3'-terminal sequences of these RNAs are different, but they can all be folded into potentially stable stem-loop structures. Those of RNA-4 and RNA-6 have inverted complementarity, potentially forming panhandle structures. Their molecular and biological properties indicate that RNAs 3a, 4, 5, and 6 are the genomes of four different viruses, which replicate independently in the same cell. These four viruses are also related to a mitochondrial RNA virus from another fungus, Cryphonectria parasitica, recently designated the type species of the Mitovirus genus of the Narnaviridae family, and to a virus from the fungus Rhizoctonia solani. It is proposed that the four O. novo-ulmi mitochondrial viruses are assigned to the Mitovirus genus and designated O. novo-ulmi mitovirus (OnuMV) 3a-Ld, 4-Ld, 5-Ld, and 6-Ld, respectively. Northern blot analysis indicated that O. novo-ulmi Ld nucleic acid extracts contain more single-stranded (ss, positive-stranded) RNA than dsRNA for all three newly described mitoviruses. O. novo-ulmi RNA-7, previously believed to be a satellite-like RNA, is shown to be a defective RNA, derived from OnuMV4-Ld RNA by multiple internal deletions. OnuMV4-Ld is therefore the helper virus for the replication of both RNA-7 and another defective RNA, RNA-10. Sequence comparisons indicate that RNA-10 could be derived from RNA-7, as previously suggested, or derived directly from RNA-4.  (+info)

The Cryphonectria parasitica gene cpmk2, which encodes a mitogen-activated protein kinase belonging to the yeast extracellular signalling-regulated kinase (YERK1) subfamily, was isolated and its biological function was examined. Disruption of cpmk2 resulted in impaired pigmentation and abolished conidiation. Growth defects were observed in the cpmk2 mutant grown on solid plates, but growth of the mutant appeared normal in liquid media, including EP complete and PD broth, suggesting that the cpmk2 gene is involved in sensing and responding to growth conditions. The mutant's production of laccase, as measured by the size of the coloured area produced on tannic-acid-supplemented plates, was significantly reduced compared with the wild-type, but the intensity of the coloured area was unchanged, suggesting that the reduced laccase activity was owing to reduced growth on solid media rather than transcriptional downregulation. A dramatic reduction observed in the canker area produced by the cpmk2 mutant
The invention relates to fungal disease resistance, in particular to resistance to blackleg disease caused by Leptosphaeria maculans. Provided are Brassica plants and seeds comprising a fragment of chromosome 8 of a wild B. rapa accession in their genome, wherein this fragment comprises a blackleg resistance locus. Further provided are molecular markers linked to the blackleg resistance locus and methods of using the markers. Brassica plants and seeds with stacked blackleg resistance loci are also provided.
Leptosphaeria maculans is the causal agent of blackleg, a serious disease on canola/rapeseed in western Canada, Australia and Europe. Genetic resistance and extended crop rotation provided effective disease control in western Canada for years but the emergence of new pathogen races has reduced the effectiveness of current management strategies. The objective of this study was to analyse L. maculans isolates derived from canola stubble in commercial fields collected in 2010 and 2011 across western Canada for the presence and frequency of avirulence (Avr) genes. A total of 674 isolates were examined for the presence of Avr alleles AvrLm1, AvrLm2, AvrLm3, AvrLm4, AvrLm6, AvrLm7, AvrLm9, AvrLepR1, AvrLepR2 and AvrLmS using a set of differential host genotypes carrying known resistance genes or PCR amplification of AvrLm1, AvrLm6 and AvrLm4-Lm7. Certain alleles were more prevalent in the pathogen population, with AvrLm6 and AvrLm7 present in ,85% of isolates, while AvrLm3, AvrLm9 and AvrLepR2 were ...
Phytopathogenic fungus Cryphonectria parasitica is the causal agent of chestnut blight in the European chestnut Castanea sativa Miller. This fungus is also the natural host of the virus Cryphonectria hypovirus 1 (CHV-1), which reduces fungal virulence and sporulation ability. Hypovirus can spread only between fungal strains that belong to the same vegetative compatibility (VC) type, i.e. that contain identical alleles at all vic loci, and less frequently from the strains in which theres a a difference in only one of six loci which determine the diversity of VC types in Europe. In this research C. parasitica populations from Ozalj and Kašt area were analyzed. The aim was to determine the diversity of VC types and the percentage of hypovirulent isolates with white morphology.

Macrophomina phaseolina is one of the most destructive necrotrophic fungal pathogens that infect more than 500 plant species throughout the world. It can grow rapidly in infected plants and subsequently produces a large amount of sclerotia that plugs the vessels, resulting in wilting of the plant. We sequenced and assembled ~49 Mb into 15 super-scaffolds covering 92.83% of the M. phaseolina genome. We predict 14,249 open reading frames (ORFs) of which 9,934 are validated by the transcriptome. This phytopathogen has an abundance of secreted oxidases, peroxidases, and hydrolytic enzymes for degrading cell wall polysaccharides and lignocelluloses to penetrate into the host tissue. To overcome the host plant defense response, M. phaseolina encodes a significant number of P450s, MFS type membrane transporters, glycosidases, transposases, and secondary metabolites in comparison to all sequenced ascomycete species. A strikingly distinct set of carbohydrate esterases (CE) are present in M. phaseolina, with the
Macrophomina phaseolina is a soil-borne fungal pathogen that causes a disease commonly known as charcoal rot. Currently, there is not an effective method for controlling the disease, because knowledge about the pathogen, the development of the disease and how it interacts with the plant host is limited. Therefore, a study is proposed to investigate the interactions between M. phaseolina and the plant species Medicago truncatula using a molecular genetics approach where the host genes involved in the disease development will be identified. We will first conduct a genetic screen in a mutant population of M. truncatula and look for strains that have altered susceptibility to M. phaseolina. We will then identify the genes that are involved in host-pathogen interactions ...
Cryphonectria hypovirus 1 (CHV1) is a double-stranded (ds)RNA virus without a capsid that infects phytopathogenic fungus Cryphonectria parasitica, the causal agent of chestnut blight. This virus reduces virulence and reproductive capacities of the fungus and thus is very important in biological control of the chestnut blight. If a hypovirulent fungus carrying CHV1 is introduced into an active canker caused by virulent C. parasitica strain, canker expansion ceases and callus is formed. The aim of this research was to evaluate the prevalence of CHV1 in chestnut calli. A total of 24 calli from Ozalj and Markuševac were included in the research. Observed presence of virulent fungal strains in chestnut calli was high. As many as 29.16% of calli had only virulent fungal strains in their tissue, 45.84% of calli had the combination of virulent and hypovirulent fungal strains, and only 25% of calli had solely hypovirulent fungal strains in their tissue. It is assumed that this could have happened ...

An allele of Pm2 for wheat powdery mildew resistance was identified in a putative Agropyron cristatum -derived line and used in wheat breeding programs. Powdery mildew (caused by Blumeria graminis f. sp. tritici, Bgt) is one of the most devastating wheat diseases worldwide. It is important to exploit varied sources of resistance from common wheat and its relatives in resistance breeding. KM2939, a Chinese breeding line, exhibits high resistance to powdery mildew at both the seedling and adult stages. It carries a single dominant powdery mildew resistance (Pm) allele of Pm2, designated Pm2b, the previous allelic designation Pm2 will be re-designated as Pm2a. Pm2b was mapped to chromosome arm 5DS and flanked by sequence characterized amplified region (SCAR) markers SCAR112 and SCAR203 with genetic distances of 0.5 and 1.3 cM, respectively. Sequence tagged site (STS) marker Mag6176 and simple sequence repeat (SSR) marker Cfd81 co-segregated with SCAR203. Pm2b differs in specificity from donors of Pm2a,
Detection and quantification of airborne ascospores as a component of the Sclerotinia rot of carrot (SRC) forecast model is currently accomplished using the blue plate test (BPT), which uses Sclerotinia semiselective medium (SSM). A quantitative polymerase chain reaction (qPCR) assay was developed to reduce the time to specifically quantify ascospores of Sclerotinia sclerotiorum from air samples collected using a Burkard Multi-Vial Cyclone Sampler. The qPCR assay was highly sensitive and detected DNA from 0.5 to 5 × 104 ascospores within a linear range (R2 = 0.99). The qPCR assay was used to quantify ascospores of S. sclerotiorum in air samples collected over three growing seasons. Initial SRC disease was observed 8 and 34 days following detection of 9.5 and 2 ascospores m-3 of air, respectively. Results from air samples collected using an Andersen N6 Sampler and the qPCR assay were compared with the BPT. Ascospore counts from a Burkard Sampler coupled with the qPCR assay and the BPT followed ...
The interaction between Stagonospora nodorum and a susceptible wheat cultivar was investigated using a range of microscopic techniques. Germination of pycnidiospores occurred approximately 3 h after making contact with the leaf surface and was followed by attempted penetration 8-12 h later. Penetration was observed through stomata and also directly through periclinal and anticlinal epidermal cell walls. Penetration down the anticlinal cell walls appeared to occur without a differentiated penetrating structure whilst structures identified as either lateral appressoria or hyphopodia were typically present when penetrating over a periclinal cell wall. Once inside the leaf, the fungus continued to grow for the next 4-5 days colonising all parts of the leaf except the vascular bundles. Only in the later phase of the infection was total host cell collapse apparent. Evidence of polyphenolic compounds was observed. The infection cycle was completed within 7 days as indicated by sporulation on the leaf ...
What does powdery mildew look like? The name of this disease is descriptive. The upper and (less frequently) lower surfaces of leaves, as well as stems of infected plants, have a white, powdery appearance. They look as though someone has sprinkled them with talcum powder or powdered sugar.. Where does powdery mildew come from? Powdery mildew is caused by several closely related fungi that survive in plant debris or on infected plants. These fungi are fairly host specific. The powdery mildew fungus that infects one type of plant (e.g., phlox) is not the same powdery mildew fungus that infects another (e.g., lilac). However, if you see powdery mildew on one plant, then weather conditions, usually high humidity, are favorable for development of the disease on a wide range of plants.. How do I save a plant with powdery mildew? DO NOT panic! For many plants, powdery mildew is a cosmetic, non-lethal disease. For other plants [e.g., phlox, Monarda, zinnia (see University of Wisconsin Garden Facts ...
Seemuller, E., 1976: Infectivity and pathogenicity of Leptosphaeria coniothyrium and other stem inhabiting fungi on raspberry canes
Hypovirus is a genus of viruses, in the family Hypoviridae. Fungi serve as natural hosts. There are currently four species in this genus including the type species Cryphonectria hypovirus 1. Diseases associated with this genus include: host virulence reduction. The diameter is around 50-80 nm. Genomes are linear, around 9-13kb in length. The genome has 1 or 2 open reading frames. Viral replication is cytoplasmic. Replication follows the double-stranded RNA virus replication model. Double-stranded RNA virus transcription is the method of transcription. The virus exits the host cell by cell to cell movement. Fungi serve as the natural host. Hypovirus CHV1 is the only hypovirus found in Europe up to 2000. It is known for reducing the virulence of the fungus that causes chestnut blight (i.e. hypovirulence). Cryphonectria parasitica, the ascomycete fungus, originated in Asia and causes the disease chestnut blight in several chestnut species (Castanea sp.). Although symptoms are mild in Asian chestnut ...
Cerato-platanin (CP) is a 120 amino acids-long protein purified from the culture filtrate of Ceratocystis fimbriata (Ell. and Halst.) Davidson f. sp. platani Walter (Cfp), the causative agent of the canker stain of the plane trees (Pazzagli et al., 1999). CP contains 4 cysteines forming two S-S bridges, Cys20-57 and Cys60-115, and has a high percentage (40%) of hydrophobic residues. It is the founder member of the cerato- platanin family, and its N-terminal region is very similar to cerato-ulmin, a class II hydrophobin involved in the pathogenesis of Dutch elm disease (Del Sorbo et al., 2002). CP is located in the Cfp cell walls, and is early-detected in Cfp culture filtrates. In in vitro experimental conditions CP self-assembles, and interacts with the host plane leaves by eliciting phytoalexin synthesis, extended cell plasmolysis and crushing, and abundant starch accumulation in the chloroplasts (Bennici et al., 2005; Boddi et al., 2004; Pazzagli et al., 2005; Scala et al., 2004). cDNA ...
Hypovirulent isolates of the fruit tree fungal pathogen Diaporthe ambigua have previously been shown to harbour a double-stranded (ds)RNA genetic element of about 4 kb. In this study, we established the complete cDNA sequence of this dsRNA, which represents a replicative form of a positive-strand RNA virus that we have named D. ambigua RNA virus (DaRV). The nucleotide sequence of the genome is 4113 bp and has a GC content of 53%. Two large ORFs are present in the same reading frame. They are most probably translated by readthrough of a UAG stop codon in the central part of the genome. The longest possible translation product (p125) has a predicted molecular mass of about 125 kDa. A significant homology can be found to the non-structural proteins of carmoviruses of the positive-strand RNA virus family Tombusviridae. These proteins also include the conserved RNA-dependent RNA polymerase (RDRP) domain. In contrast to the genome organization of these plant viruses, no ORF is present at the 3′ end of the
Gray leaf spot, caused by Cercospora zeae-maydis, is one of the most destructive foliar diseases of maize worldwide. C. zeae-maydis orients hyphal growth towards stomata (stomatal tropism) and forms infectious structures (appressoria) that are necessary for successful infection. Although some genes involved in pathogenesis in C. zeae-maydis have been identified, the molecular mechanisms are not well understood. In fungi, heterotrimeric G-proteins consist of three subunits (α, β, and γ) and mediate responses to environmental stimuli. They regulate diverse functions, including nutrient detection, virulence, fungal development, conidiation, secondary metabolism, and pathogenesis in many plant pathogenic fungi. This research explored the role of each G-protein α (Gpα) subunit of C. zeae-maydis in pathogenesis. To this end, the three Gpα subunits identified in C. zeae-maydis were functionally characterized. All three Gpα genes were required for appressorium formation and pathogenesis. Additionally,

The phylum Ascomycota is by far the largest group in the fungal kingdom. Ecologically important mutualisticassociations such as mycorrhizae and lichens have evolved in this group, which are regarded as keyinnovations that supported the evolution of land plants. Only a few attempts have been made to date theorigin of Ascomycota lineages by using molecular clock methods, which is primarily due to the lack ofsatisfactory fossil calibration data. For this reason we have evaluated all of the oldest available ascomycetefossils from amber (Albian to Miocene) and chert (Devonian and Maastrichtian). The fossils representfive major ascomycete classes (Coniocybomycetes, Dothideomycetes, Eurotiomycetes, Laboulbeniomycetes,and Lecanoromycetes). We have assembled a multi-gene data set (18SrDNA, 28SrDNA, RPB1 andRPB2) from a total of 145 taxa representing most groups of the Ascomycota and utilized fossil calibrationpoints solely from within the ascomycetes to estimate divergence times of Ascomycota lineages ...

Inoculation of wheat seedlings with certain combinations of isolates of Septoria tritici resulted in marked reductions in pycnidial coverage of leaves compared with plants inoculated separately with individual components of the mixture. The effect was greater when the isolates were grown together than when grown separately and mixed before inoculation. The suppression of pycnidial formation did not depend on the ratio of the isolates in the mixtures. The addition of a culture filtrate from one isolate to the conidial preparation of another isolate resulted in marked symptom suppression. In conidial preparations where the growth medium was decanted and the spores were resuspended in fresh medium, marked reductions in pycnidial coverages were observed on all cultivars. These results suggest that S. tritici may produce substances that regulate the expression of symptoms on wheat leaves inoculated with isolate mixtures. Challenge inoculations of Kavkaz winter wheat with an isolate several days after ...

The ethyl acetate extract of the culture filtrate of the marine Ascomycete, Leptosphaeria oraemaris (Linder) yielded a novel metabolite designated by the common name leptosphaerin. An x-ray crystallographic structure analysis was disproved by the synthesis of 3-acetoxy-S-(1,2-dihydroxyethyl)- 3-pyrrolin-2-one 1, starting with N,N-dibenzylhydroxylamine 47 and D-mannitol 44. Oxidation of 47 followed by acid catalyzed hydrolysis gave N-benzylhydroxylamine 4_9. D-mannitol 44 was converted to a bis acetonide and the resulting vicinal diol was cleaved with lead tetraacetate to afford 2.3-0-isopropylidene-D-glyceraldehyde 46. Condensation of 46 and 49 gave N-benzyl-N-(2,3-0-isopropylideneglyceraldimine)-N-oxide 50 which, upon thermolyeis in the presence of methyl acryiate yielded 2- benzy1-3-(1,2-0-isopropylidene dihydroxyethyl)-S-carbomethoxyisoxazolidine 7S. Catalytic hydrogerolysis followed by oxidation and acetylation produced 3-acetoxy-5-(1,2-0-isopropylidenedihydroxyetnyi)-3-pyrroline-2- one 81. ...

Development of a method for mRNA differential display in filamentous fungi: comparison of mRNA differential display reverse transcription polymerase chain reaction and cDNA amplified fragment length polymorphism in Leptosphaeria maculans
A concern associated with the growing of genetically modified (GM) crops is that they could adversely affect non-target organisms. We assessed the impact of several transgenic powdery mildew-resistant spring wheat lines on insect herbivores. The GM lines carried either the Pm3b gene from hexaploid wheat, which confers race-specific resistance to powdery mildew, or the less specific anti-fungal barley seed chitinase and β-1,3-glucanase. In addition to the non-transformed control lines, several conventional spring wheat varieties and barley and triticale were included for comparison. During two consecutive growing seasons, powdery mildew infection and the abundance of and damage by naturally occurring herbivores were estimated under semi-field conditions in a convertible glasshouse and in the field. Mildew was reduced on the Pm3b-transgenic lines but not on the chitinase/glucanase-expressing lines. Abundance of aphids was negatively correlated with powdery mildew in the convertible glasshouse, with Pm3b
First, I would personally suspect that black dots, especially if appearing flush or bulging slightly from the surface, are pycnidia, not budding isidia. Isidiate species (and sorediate species) almost invariably produce isidia (and soredia) from a very early stage, much earlier than a fertile species would begin to produce apothecia (which apparently require a much greater investment). Fertile species, for whatever reason, frequently also have pycnidia. Sometimes sterile species do, but its a useful correlation: abundant pycnidia on a thallus with no soredia, isidia, or apothecia generally indicates an immature fertile species. (Ive heard suggested that the conidia produced by pycnidia can actually function as "sperm" or "pollen", a very inrtriguing possibility.). The other, and more important point, is the importance of distinguishing chemical spot tests done on the cortex versus on the medulla. I, too, am convinced that this specimen is Parmelina, which as you point out should have lecanoric ...

Fungal plant pathogens produce secreted proteins adapted to function outside fungal cells to facilitate colonization of their hosts. In many cases such as for fungi from the Sclerotiniaceae family the repertoire and function of secreted proteins remains elusive. In the Sclerotiniaceae, whereas Sclerotinia sclerotiorum and Botrytis cinerea are cosmopolitan broad host-range plant pathogens, Sclerotinia borealis has a psychrophilic lifestyle with a low optimal growth temperature, a narrow host range and geographic distribution. To spread successfully, S. borealis must synthesize proteins adapted to function in its specific environment. The search for signatures of adaptation to S. borealis lifestyle may therefore help revealing proteins critical for colonization of the environment by Sclerotiniaceae fungi. Here, we analyzed amino acids usage and intrinsic protein disorder in alignments of groups of orthologous proteins from the three Sclerotiniaceae species. We found that enrichment in Thr, depletion in

Leaves covered by powdery mildew cannot manufacture enough food which can impact on plant growth and fruit development, depending on the rate of infection. But rarely does the mildew kill the plant. It just looks horrible.. There are a number of different fungi species responsible for powdery mildew. Some are species specific, others will attack a wider range of plant varieties. In regions of high humidity and moderate temperatures, the fungi produce mycelium and spores on the surface of affected foliage. The spores are then carried by wind currents to other plants.. Strangely enough, it is the wind which will reduce the risk of fungal infection. Providing adequate spacing between plants will increase air circulation and decrease the moisture retention on the leaves. Opening up shaded areas to more sunlight will also help.. Autumn is another trying time of year for protecting our plants and crops from powdery mildew. A lot of fungi spores repose in the soil and come fall, the rains splashing up ...
Prevent powdery mildew infections by providing good air circulation, keeping the trumpet vine healthy and removing and destroying fallen infected leaves. Mild to moderate infections rarely warrant chemical control because they cause cosmetic damage rather than long-term damage. However, chemical fungicides can help control severe cases that threaten the vitality of the plant. Remove and destroy infected leaves to prevent leaf spot infections from spreading. Increase air circulation by pruning overgrown vines to prevent infection from leaf spot fungi. Because leaf spot diseases rarely cause significant damage to the vine, fungicides arent necessary.. ...
Photo 2. Canker with hypovirus. The tree has enclosed the canker with wound tissue that stops canker expansion. The canker in this picture has died (bare wood at the center of the stem, and the wound tissue is slowly covering the old infection site.. Our work on hypoviruses began in 2010 when we introduced hypovirus onto ten trees in an orchard of Japanese-European hybrids on the MSU campus that is infected with blight. One or two cankers per tree were inoculated with hypovirus. Our first goal is to determine if hypovirus treatments result in healing cankers. This will be accomplished by monitoring the treated cankers for three to five years to document that treatments halt canker expansion and lead to tree recovery. A second goal is to determine how well hypovirus spreads to untreated cankers on a tree. The extent of spread to new cankers on a treated tree will influence how hypoviruses are used. If the hypovirus spread quickly in orchard situations, then only a few cankers need to be treated ...

Genetic variation between individuals is essential to evolution and adaptation. However, intra-organismic genetic variation also shapes the life histories of many organisms, including filamentous fungi. A single fungal syncytium can harbor thousands or millions of mobile and potentially genotypically different nuclei, each having the capacity to regenerate a new organism. Because the dispersal of asexual or sexual spores propagates individual nuclei in many of these species, selection acting at the level of nuclei creates the potential for competitive and cooperative genome dynamics. Recent work in Neurospora crassa and Sclerotinia sclerotiorum has illuminated how nuclear populations are coordinated for fungal growth and other behaviors and has revealed both molecular and physical mechanisms for preventing and policing inter-genomic conflict. Recent results from population-level genomic studies in a variety of filamentous fungi suggest that nuclear exchange between mycelia and recombination ...

We explored the potential of the cox1 gene in the species resolution of soil fungi and compared it with the nuclear internal transcribed spacer (ITS) and small subunit (SSU)-rDNA. Conserved primers allowing the amplification of the fungal cox1 gene were designed, and a total of 47 isolates of Zygomycota and Ascomycota were investigated. The analysis revealed a lack of introns in >90% of the isolat ...
A grapevine hybrid progeny was generated to track the inheritance of the Ren1 and the Run1 powdery mildew resistance alleles and the segregation of the powdery mildew resistance phenotype. Genotypic analysis was carried out using flanking microsatellite markers; phenotypic evaluations were done under in vitro and greenhouse conditions. Pairing the phenotypic and genotypic data demonstratedthat Ren1 and Run1 acted as single dominant loci and assorted independentlywithout considerable distortion of segregation. Chromosomal recombination events were detected in the Ren1 but not in the Run1 region, corroborating earlier observations that crossover between homologous chromosomes was suppressed around the Run1 locus. Taken together, the results confirmedthat microsatellite marker-assisted selection is a reliable and expeditious method to combine multiple alleles that confer resistance to a pathogen. ...

Abstract: A high-performing detection method is essential to safeguard those countries that are still unaffected by canker stain, a devastating disease of Platanus spp. caused by Ceratocystis platani. We previously developed EvaGreen and Taqman-based Real-Time PCR to detect this pathogen, but in-depth validation is needed to guarantee users about its effectiveness and promote its utilization. In this work we present a validation study designed according to EPPO standards, focusing on the analytical and diagnostic sensitivity and specificity. We extend its technical application using SYBR Green. By performing standard curves and eight-replication-based experiments, we established the detection limit at 3 fg C. platani gDNA per PCR reaction. The repeatability and the operator-based reproducibility of the Real-Time PCR was demonstrated. Different gDNA extraction events by different operators and different gDNA extraction modalities did not affect the detection limit. The detection limit threshold cycle was

The phylogenetic position of the Tasmanian endemic genus Cameronia Kantvilas is studied using partial sequences of nuclear LSU and mitochondrial SSU ribosomal DNA. Monophyly of the genus is supported, as is its placement in Ostropomycetidae, although its position within this subclass remains uncertain. Given the lack of close relatives to Cameronia and its morphological differences compared to other families with perithecioid ascomata in Ostropomycetidae, the new family Cameroniaceae Kantvilas & Lumbsch is proposed.
Most all powdery mildew create the same basic symptoms, so despite the fungi being of different species, they are grouped together under this common name due to their effect on plants. The first sign is usually small spots or patches of gray or white with a talcum-powder-like look. Very close inspection will show tiny spherical structures that are the spore houses for the fungus.. It most often appears on the upper (skyward) side of the leaf, the outer edge of flowers, and the top portion of fruits - and stems. On plants that were affected the previous year, the over-winter spores (cleistothecia) will be black scaly-appearing clumps on the stem or leaf.. ...
Although the common conception of microbes is of isolated and individualistic cells, cells can also cooperate to overcome challenges on dispersal, growth or feeding in difficult physical environments. Highlighting two examples, Ill show how new mathematical models reveal the benefits of inter-cellular cooperation and expose the developmental and stability barriers against cooperation, illuminating the ecology of important pathogens or model organisms. 1. Sclerotinia sclerotiorum is a devastating crop pathogen endemic to more than 40 species of crops across North America. Infections spread across and between fields by the ejection of airborne spores from mature fruiting bodies. The virulence of new infections is remarkable considering that individually ejected spores travel only a few mm before being stopped by air drag. Direct numerical simulations of the coupled dynamics of spores and the surrounding air show that hydrodynamic interactions between spores drive macroscopic winds that greatly ...

Tan spot or yellow (leaf) spot disease of wheat (Triticum spp.) is caused by Pyrenophora tritici-repentis, a necrotrophic fungal pathogen that is wide-spread throughout the main wheat-growing regions in the world. This disease is currently the single most economically important crop disease in Australia. IN this study, a real-time quantitative polymerase chain reaction (qPCR) assay was developed as a diagnostic tool to detect the pathogen on wheat foliar tissue. A multicopy locus (PtrMulti) present in the P. tritici-repentis genome was assessed for its suitability as a qPCR probe. The primer pair PtrMulti_F/R that targets the region was evaluated with respect to species specificity and sensitivity. A PtrMulti SYBR qPCR assay was developed and proved to be suitable for the identification and relative quantification of P. tritici-repentis with a detection limi of DNA levels at ,0.1 pg. Variation of the PtrMulti copy number between the geographical representatives of P. tritici-repentis strains ...
American chestnut is a tree of great historical, ecological, and economical importance. It once dominated forests in eastern United States until the introduction of chestnut blight fungus (Cryphonectria parasitica) in the late 19th century. Within 50 years, C. parasitica killed almost all of the 4 billion American chestnut trees in the eastern United States. The fungus first infects wounded stem, secretes oxalic acid to decrease the pH of the infected tissue to toxic levels for the tree, but optimum for fungal enzymes, and then mycelia fans spread forming a canker which when it girdles a branch prevents water and nutrient transport, eventually killing the tree above the canker. The fungus does not infect the roots, thus allowing the growth of adventitious shoots to keep the tree alive. However, this survival is only temporary because these spouts will again get infected by the fungus and die back to the ground. It is this continuing circle that made American chestnut, once a great canopy tree, ...

Pyrenophora tritici-repentis, the causal organism of the necrotrophic foliar wheat disease tan spot [also known as yellow (leaf) spot in Australia] is an important disease in Australia and in many parts of the world. North American isolates of the pathogen have been shown to produce combinations of three host-specific toxins, ToxA, ToxB and ToxC. Each toxin interacts with a host sensitivity locus, respectively Tsn1, Tsc2 and Tsc1. The virulence of an isolate is partially correlated with the presence of these toxins and resistance in the host is associated with absence of the sensitivity loci. Breeding for resistance to tan spot can, therefore, be aided by knowledge of the prevalence of the toxin-encoding genes in local pathogen populations. Two of the toxins, A and B, are encoded by known genes and molecular tests for the genes have been developed. We screened a diverse collection of 119 tan spot isolates collected between 1984 and 2008 and from all affected regions of Australia (Queensland, New ...
Synthetic hexaploid wheats (SHWs) are an important component of the breeding programs of the International Maize and Wheat Improvement Center (CIMMYT). CIMMYT germplasm is the most important source of genetic resources for wheat breeding programs in Iran, but their utilization has to be examined prior to their incorporation into breeding programs. This study was conducted to evaluate the resistance of 128 CIMMYT SHWs to septoria tritici blotch (STB), a destructive wheat disease caused by Zymoseptoria tritici. Wheat seedlings were inoculated with Z. tritici spores in the greenhouse, kept at 20-22ºC and scored 21 days post inoculation by estimating the percentage of necrotic lesions bearing pycnidia. Inter simple sequence repeat (ISSR) markers revealed that 11 Z. tritici isolates had high genetic variability. The isolates varied in their virulence towards SHWs. Among all interactions (n=1408), 304 resistance responses were identified. Of 128 genotypes, 60 synthetic hexaploid wheat genotypes showed no
Infection of barley leaves by powdery mildew (Erysiphe graminis f.sp. hordei) causes increased dark respiration, par tof which is associated with active host responses to infection, and a consequence of which is reduced plant growth. The pathogen cannot be grown separately from the host. Therefore, in order to examine those changes in respiratory activity peculiar to the host, attempts were made to isolate protoplasts from infected tissues, and from healthy controls. Isolation of useful numbers (, 106cm−6) of viable mesophyll protoplasts from infected tissues was possible with one among several batches of commercial Cellulysin tested; on analysis by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE), this batch contained a low molecular weight protein at 20.1 kDa not found in other batches. In all isolated protoplasts, total respiration increased with the age of the source-leaf, but within 24 h of inoculation respiration was stimulated by infection. Protoplasts from ...
This study tested the effectiveness of single and combined applications of Trichoderma and rhizobacterial strains to control white root rot (WRR) caused by Rosellinia necatrix in avocado plants. Three Trichoderma, two T. atroviride and one T. virens monoconidal strains and four bacterial strains (Bacillus subtilis, Pseudomonas pseudoalcaligenes and two P. chlororaphis) were assayed to determine their compatibilities in vitro. In addition, the effects of the bacterial filtrates were evaluated against the Trichoderma strains and reciprocally; these filtrates were applied alone or in combination to determine their effectiveness against R. necatrix. Individual control agents or combinations of them were applied to avocado plants that were artificially inoculated with a virulent R. necatrix strain. Compatibility between the combined Trichoderma applications and the bacterial strains was observed and these combinations significantly improved the control of R. necatrix during the in vitro experiments. ...
There are few diseases of chestnut trees in North America. However, the one disease chestnut trees have, chestnut blight, is still thought of as one of the worst tree diseases in history.. Chestnut blight has killed more chestnut trees around the world than any other forest disease. The fungus that causes chestnut blight can be traced from China and Japan where it did not cause much disease when compared to North America and Europe where it killed several billion trees. More recently it was found in Australian chestnut orchards and they destroyed several orchards and thousands of trees to hopefully eradicate this disease.. Chestnut blight has the deserved reputation of being impossible to manage when growing chestnut blight-susceptible trees, such as American chestnut. The only species with resistance to the blight fungus are Chinese and Japanese chestnut trees. In Michigan, we primarily grow Chinese trees or European X Japanese hybrid cultivars. While the Chinese trees are chestnut ...
Toll-like receptors (TLRs), which recognize a wide range of microbial pathogens and pathogen-related products, play important roles in innate immunology. Macrophages have a variety of TLRs, and pathogen binding to TLR resulted in the activation of macrophages. R-848, an immune response modifier, is an analog of imidazoquinoline derivative and binds to an endosome-localized TLR to exert an anti-viral response on leukocytes. In the present study, we verified that co-treatment of R-848 with other TLR agonists would enhance immune response. The culture supernatant of Aureobasidium pullulans (A. pullulans, which contains predominantly soluble β-glucan), which binds to cell membrane-localized TLR, and to C-type lectin receptor Dectin-1, was treated together with R-848 to THP-1 macrophages. Compared to R-848 treatment alone, co-treatment of R-848 with A. pullulans culture supernatant significantly augmented TNF-α and IL-12p40 cytokine expression. Next, we investigated whether or not apoptotic cell uptake
The fungus Pyrenophora tritici-repentis is a major pathogen of wheat worldwide, causing the leaf spotting disease tan spot. To best inform approaches for plant genetic resistance, an understanding of the biology and pathogenicity mechanisms of this fungal pathogen is essential. Here, intracellular and extracellular proteins of P. tritici-repentis were extracted, and peptides analysed via high-resolution mass spectrometry. Our objective was to generate a useful proteomics resource for P. tritici-repentis. A survey of proteins secreted by the pathogen into culture filtrate is especially useful, as these are likely to come in direct contact with the wheat host and may play important roles in infection/pathogenicity. The peptide data presented herein, has also been used to successfully verify and refine in silico predicted P. tritici-repentis gene annotations, through the validation of alternative splicing and reading frame shifts. The data sets presented consist of peptide spectra of the extracellular and
Management of M. phaseolina involves a combination of cultural practices and chemical methods. Cultivars differ in their susceptibility to charcoal rot: Strawberry Festival is highly susceptible, Florida Radiance is moderately susceptible, and Sweet Sensation® Florida 127 is moderately resistant. New cultivars developed by the University of Florida breeding program are tested for their susceptibility to M. phaseolina every season. Pre-plant soil fumigation is the standard method employed by growers to reduce inoculum levels and control charcoal rot. Methyl bromide was highly effective in controlling the pathogen. Since its phase-out, strawberry growers have transitioned to alternative broad-spectrum fumigants. Studies performed at the UF/IFAS Gulf Coast Research and Education Center (GCREC) in Balm, FL, at the Florida Strawberry Growers Association in Dover, and on commercial farms demonstrated that Telone®, K-pam®, Vapam®, Paladin®, and Dominus® applied through shank or drip tapes ...

The fungus exclusively targets the brain and infections have a grave prognosis. Eighteen cases have been reported in the literature from 1983 to 2004 with almost 100% mortality. Our patient presented in February 2008 with a brain abscess while receiving chemotherapy for carcinoma of the breast. Diagnosis was by craniotomy and aspiration of the brain abscess. Direct microscopy showed dematiaceous fungal hyphae. R. mackenziei was recovered in ...

Three new 14-membered resorcylic acid lactones, two with a rare natural acetonide group and one with a 5-chloro-substituted lactone, named cochliomycins A-C (1-3), together with four known analogues, zeaenol (4), LL-Z1640-1 (5), LL-Z1640-2 (6), and paecilomycin F (7), were isolated from the culture broth of Cochliobolus lunatus, a fungus obtained from the gorgonian Dichotella gemmacea collected in the South China Sea. Their structures and the relative configurations of 1-3 were elucidated using comprehensive spectroscopic methods including NOESY spectra and chemical conversions. A transetherification reaction was also observed in which cochliomycin B (2) in a solution of CDCl3 slowly rearranged to give cochliomycin A (1) at room temperature. These resorcylic acid lactones were evaluated against the larval settlement of barnacle Balanus amphitrite, and antifouling activity was detected for the first time for this class of metabolites. The antibacterial and cytotoxic activities of these compounds ...
Diseases are a major factor limiting the yield of soybean (Glycine max (L.) Merr.). Brown stem rot of soybean, caused by Phialophora gregata (Allington and Chamberlain) W. Gams, and phytophthora root rot, caused by Phytophthora sojae Kaufmann & Gerdemann, are major diseases of soybean in Illinois. A gene for resistance to powdery mildew, caused by Microsphaera diffusa Cke. & Pk., has also been found to be linked to a gene for phytophthora resistance. A field study was conducted to determine yield differences between isolines carrying different alleles at the locus for powdery mildew resistance, greenhouse experiments were performed to study the inheritance of brown stem rot resistance, and laboratory experiments were conducted in attempts to find molecular markers linked to brown stem rot, phytophthora, and powdery mildew resistance in soybean ...
Powdery mildews are one of the most common diseases of ornamental plants; many nursery, flower, vegetables, and woody plants are susceptible. Greenhouse crops prone to infection include African violet, Begonia , Dahlia , gerbera daisy, Hydrangea , roses, Verbena, Kalanchoe, and Poinsettia. Herbaceous perennials particularly susceptible to Powdery mildew include Aster, Centaurea, Coreopsis, Delphinium, Monarda, Phlox, Rudebeckia, and Sedum. The disease is easily recognizable as a white to gray powdery growth on leaves and sometimes stems and flowers. Powdery mildew may have little or no affect on the plant (other than aesthetic) or it may cause infected leaves to distort, discolor, wither, and defoliate prematurely. Most Powdery mildews have evolved to avoid killing their hosts because they can only survive in living plant tissue. Symptoms and their severity depend upon the cultivar or species of host plant, the powdery mildew species, environmental conditions, and the age of plant tissue when it ...
The efficiency with which the nematophagous fungus Arthrobotrys dasguptae attached to a range of plant parasitic nematodes was studied. Rotylenchus spp. and criconematid species retained many more detachable adhesive knobs than did other plant parasitic nematodes. More adhesive knobs were found on the anterior end of Rotylenchus robustus than on any other part of the body. The knobs attached only to one of the species tested in the genera Longidorus, Xiphinema, Trichodorus and Paratrichodorus. Tests with a range of fluorescent lectins indicated that only a restricted number of carbohydrate moieties were present on the cuticle of R. robustus whereas none were found on Xiphinema diversicaudatum. Saturating fungus and nematodes with these lectins or their specific carbohydrates did not affect the subsequent adhesion of A. dasguptae to the cuticle of R. robustus.
