Cloning and partial characterization of endopolygalacturonase genes from Botrytis cinerea. (1/339)

Botrytis cinerea is a plant-pathogenic fungus infecting over 200 different plant species. We use a molecular genetic approach to study the process of pectin degradation by the fungus. Recently, we described the cloning and characterization of an endopolygalacturonase (endoPG) gene from B. cinerea (Bcpg1) which is required for full virulence. Here we describe the cloning and characterization of five additional endoPG-encoding genes from B. cinerea SAS56. The identity at the amino acid level between the six endoPGs of B. cinerea varied from 34 to 73%. Phylogenetic analysis, by using a group of 35 related fungal endoPGs and as an outgroup one plant PG, resulted in the identification of five monophyletic groups of closely related proteins. The endoPG proteins from B. cinerea SAS56 could be assigned to three different monophyletic groups. DNA blot analysis revealed the presence of the complete endoPG gene family in other strains of B. cinerea, as well as in other Botrytis species. Differential gene expression of the gene family members was found in mycelium grown in liquid culture with either glucose or polygalacturonic acid as the carbon source.  (+info)

Processing, targeting, and antifungal activity of stinging nettle agglutinin in transgenic tobacco. (2/339)

The gene encoding the precursor to stinging nettle (Urtica dioica L. ) isolectin I was introduced into tobacco (Nicotiana tabacum). In transgenic plants this precursor was processed to mature-sized lectin. The mature isolectin is deposited intracellularly, most likely in the vacuoles. A gene construct lacking the C-terminal 25 amino acids was also introduced in tobacco to study the role of the C terminus in subcellular trafficking. In tobacco plants that expressed this construct, the mutant precursor was correctly processed and the mature isolectin was targeted to the intercellular space. These results indicate the presence of a C-terminal signal for intracellular retention of stinging nettle lectin and most likely for sorting of the lectin to the vacuoles. In addition, correct processing of this lectin did not depend on vacuolar deposition. Isolectin I purified from tobacco displayed identical biological activities as isolectin I isolated from stinging nettle. In vitro antifungal assays on germinated spores of the fungi Botrytis cinerea, Trichoderma viride, and Colletotrichum lindemuthianum revealed that growth inhibition by stinging nettle isolectin I occurs at a specific phase of fungal growth and is temporal, suggesting that the fungi had an adaptation mechanism.  (+info)

Requirement of functional ethylene-insensitive 2 gene for efficient resistance of Arabidopsis to infection by Botrytis cinerea. (3/339)

Inoculation of wild-type Arabidopsis plants with the fungus Alternaria brassicicola results in systemic induction of genes encoding a plant defensin (PDF1.2), a basic chitinase (PR-3), and an acidic hevein-like protein (PR-4). Pathogen-induced induction of these three genes is almost completely abolished in the ethylene-insensitive Arabidopsis mutant ein2-1. This indicates that a functional ethylene signal transduction component (EIN2) is required in this response. The ein2-1 mutants were found to be markedly more susceptible than wild-type plants to infection by two different strains of the gray mold fungus Botrytis cinerea. In contrast, no increased fungal colonization of ein2-1 mutants was observed after challenge with avirulent strains of either Peronospora parasitica or A. brassicicola. Our data support the conclusion that ethylene-controlled responses play a role in resistance of Arabidopsis to some but not all types of pathogens.  (+info)

Redox chemistry in laccase-catalyzed oxidation of N-hydroxy compounds. (4/339)

1-Hydroxybenzotriazole, violuric acid, and N-hydroxyacetanilide are three N-OH compounds capable of mediating a range of laccase-catalyzed biotransformations, such as paper pulp delignification and degradation of polycyclic hydrocarbons. The mechanism of their enzymatic oxidation was studied with seven fungal laccases. The oxidation had a bell-shaped pH-activity profile with an optimal pH ranging from 4 to 7. The oxidation rate was found to be dependent on the redox potential difference between the N-OH substrate and laccase. A laccase with a higher redox potential or an N-OH compound with a lower redox potential tended to have a higher oxidation rate. Similar to the enzymatic oxidation of phenols, phenoxazines, phenothiazines, and other redox-active compounds, an "outer-sphere" type of single-electron transfer from the substrate to laccase and proton release are speculated to be involved in the rate-limiting step for N-OH oxidation.  (+info)

The BMP1 gene is essential for pathogenicity in the gray mold fungus Botrytis cinerea. (5/339)

In Magnaporthe grisea, a well-conserved mitogen-activated protein (MAP) kinase gene, PMK1, is essential for fungal pathogenesis. In this study, we tested whether the same MAP kinase is essential for plant infection in the gray mold fungus Botrytis cinerea, a necrotrophic pathogen that employs infection mechanisms different from those of M. grisea. We used a polymerase chain reaction-based approach to isolate MAP kinase homologues from B. cinerea. The Botrytis MAP kinase required for pathogenesis (BMP) MAP kinase gene is highly homologous to the M. grisea PMK1. BMP1 is a single-copy gene. bmp1 gene replacement mutants produced normal conidia and mycelia but were reduced in growth rate on nutrient-rich medium. bmp1 mutants were nonpathogenic on carnation flowers and tomato leaves. Re-introduction of the wild-type BMP1 allele into the bmp1 mutant restored both normal growth rate and pathogenicity. Further studies indicated that conidia from bmp1 mutants germinated on plant surfaces but failed to penetrate and macerate plant tissues. bmp1 mutants also appeared to be defective in infecting through wounds. These results indicated that BMP1 is essential for plant infection in B. cinerea, and this MAP kinase pathway may be widely conserved in pathogenic fungi for regulating infection processes.  (+info)

A new method to monitor airborne inoculum of the fungal plant pathogens Mycosphaerella brassicicola and Botrytis cinerea. (6/339)

We describe a new microtiter immunospore trapping device (MTIST device) that uses a suction system to directly trap air particulates by impaction in microtiter wells. This device can be used for rapid detection and immunoquantification of ascospores of Mycosphaerella brassicicola and conidia of Botrytis cinerea by an enzyme-linked immunosorbent assay (ELISA) under controlled environmental conditions. For ascospores of M. brassicicola correlation coefficients (r(2)) of 0.943 and 0.9514 were observed for the number of MTIST device-impacted ascospores per microtiter well and the absorbance values determined by ELISA, respectively. These values were not affected when a mixed fungal spore population was used. There was a relationship between the number of MTIST device-trapped ascospores of M. brassicicola per liter of air sampled and the amount of disease expressed on exposed plants of Brassica oleracea (Brussels sprouts). Similarly, when the MTIST device was used to trap conidia of B. cinerea, a correlation coefficient of 0.8797 was obtained for the absorbance values generated by the ELISA and the observed number of conidia per microtiter well. The relative collection efficiency of the MTIST device in controlled plant growth chambers with limited airflow was 1.7 times greater than the relative collection efficiency of a Burkard 7-day volumetric spore trap for collection of M. brassicicola ascospores. The MTIST device can be used to rapidly differentiate, determine, and accurately quantify target organisms in a microflora. The MTIST device is a portable, robust, inexpensive system that can be used to perform multiple tests in a single sampling period, and it should be useful for monitoring airborne particulates and microorganisms in a range of environments.  (+info)

The hypersensitive response facilitates plant infection by the necrotrophic pathogen Botrytis cinerea. (7/339)

BACKGROUND: Plants have evolved efficient mechanisms to combat pathogen attack. One of the earliest responses to attempted pathogen attack is the generation of oxidative burst that can trigger hypersensitive cell death. This is called the hypersensitive response (HR) and is considered to be a major element of plant disease resistance. The HR is thought to deprive the pathogens of a supply of food and confine them to initial infection site. Necrotrophic pathogens, such as the fungi Botrytis cinerea and Sclerotinia sclerotiorum, however, can utilize dead tissue. RESULTS: Inoculation of B. cinerea induced an oxidative burst and hypersensitive cell death in Arabidopsis. The degree of B. cinerea and S. sclerotiorum pathogenicity was directly dependent on the level of generation and accumulation of superoxide or hydrogen peroxide. Plant cells exhibited markers of HR death, such as nuclear condensation and induction of the HR-specific gene HSR203J. Growth of B. cinerea was suppressed in the HR-deficient mutant dnd1, and enhanced by HR caused by simultaneous infection with an avirulent strain of the bacterium Pseudomonas syringae. HR had an opposite (inhibitory) effect on a virulent (biotrophic) strain of P. syringae. Moreover, H(2)O(2) levels during HR correlated positively with B. cinerea growth but negatively with growth of virulent P. syringae. CONCLUSIONS: We show that, although hypersensitive cell death is efficient against biotrophic pathogens, it does not protect plants against infection by the necrotrophic pathogens B. cinerea and S. sclerotiorum. By contrast, B. cinerea triggers HR, which facilitates its colonization of plants. Hence, these fungi can exploit a host defense mechanism for their pathogenicity.  (+info)

Identification and characterization of a hexapeptide with activity against phytopathogenic fungi that cause postharvest decay in fruits. (8/339)

A hexapeptide of amino acid sequence Ac-Arg-Lys-Thr-Trp-Phe-Trp-NH2 was demonstrated to have antimicrobial activity against selected phytopathogenic fungi that cause postharvest decay in fruits. The peptide synthesized with either all D- or all L-amino acids inhibited the in vitro growth of strains of Penicilium italicum, P. digitatum, and Botrytis cinerea, with MICs of 60 to 80 microM and 50% inhibitory concentration (IC50) of 30 to 40 microM. The inhibitory activity of the peptide was both sequence- and fungus-specific since (i) sequence-related peptides lacked activity (including one with five residues identical to the active sequence), (ii) other filamentous fungi (including some that belong to the genus Penicllium) were insensitive to the peptide's antifungal action, and (iii) the peptide did not inhibit the growth of several yeast and bacterial strains assayed. Experiments on P. digitatum identified conidial germination as particularly sensitive to inhibition although mycelial growth was also affected. Our findings suggest that the inhibitory effect is initially driven by the electrostatic interaction of the peptide with fungal components. The antifungal peptide retarded the blue and green mold diseases of citrus fruits and the gray mold of tomato fruits under controlled inoculation conditions, thus providing evidence for the feasibility of using very short peptides in plant protection. This and previous studies with related peptides indicate some degree of peptide amino acid sequence and structure conservation associated with the antimicrobial activity, and suggest a general sequence layout for short antifungal peptides, consisting of one or two positively charged residues combined with aromatic amino acid residues.  (+info)

The genetic architecture of plant defense against microbial pathogens may be influenced by pathogen lifestyle. While plant interactions with biotrophic pathogens are frequently controlled by the action of large-effect resistance genes that follow classic Mendelian inheritance, our study suggests that plant defense against the necrotrophic pathogen Botrytis cinerea is primarily quantitative and genetically complex. Few studies of quantitative resistance to necrotrophic pathogens have used large plant mapping populations to dissect the genetic structure of resistance. Using a large structured mapping population of Arabidopsis thaliana, we identified quantitative trait loci influencing plant response to B. cinerea, measured as expansion of necrotic lesions on leaves and accumulation of the antimicrobial compound camalexin. Testing multiple B. cinerea isolates, we identified 23 separate QTL in this population, ranging in isolate-specificity from being identified with a single isolate to controlling ...
The plant hormone ethylene regulates fruit ripening, other developmental processes, and a subset of defense responses. Here, we show that 1-aminocyclopropane-1-carboxylic acid synthase (ACS)-silenced apple (Malus domestica) fruit that express a sense construct of ACS were more susceptible to Botrytis cinerea than untransformed apple, demonstrating that ethylene strengthens fruit resistance to B. cinerea infection. Because ethylene response factors (ERFs) are known to contribute to resistance against B. cinerea via the ethylene-signaling pathway, we cloned four ERF cDNAs from fruit of M. domestica: MdERF3, -4, -5, and -6. Expression of all four MdERF mRNAs was ethylene dependent and induced by wounding or by B. cinerea infection. B. cinerea infection suppressed rapid induction of wound-related MdERF expression. MdERF3 was the only mRNA induced by wounding and B. cinerea infection in ACS-suppressed apple fruit, although its induction was reduced compared with wild-type apple. Promoter regions of ...

Succinate dehydrogenase (Sdh) inhibitor fungicides, such as boscalid, are effective for the management of gray mold caused by the fungal pathogen Botrytis cinerea. Unfortunately, resistance to boscalid was common among isolates of the pathogen from small fruits grown in Oregon. Boscalid-resistance is commonly associated with mutations in Sdh, especially in subunit B. SdhB was sequenced from five boscalid-sensitive and five boscalid-resistant isolates of B. cinerea. A majority of the boscalid-resistant isolates had a single nucleotide polymorphism at codon 272 resulting in a substitution of histidine with arginine (H272R). The boscalid-sensitive isolates did not harbor this mutation. The transposons Boty and Flipper also were found within the genomes of the resistant strains, but not boscalid-sensitive isolates. Additionally, a pattern was found to exist between the transposons present within the strains and source location. Additional studies with a greater number of isolates are required to ...
Botrytis cinerea est le champignon pathogène responsable de la pourriture grise. Cette maladie est économiquement importante, car elle détruit chaque année une partie des récoltes viticoles et horticoles (fraises, concombres, tomates…). Ce champignon infecte les baies de raisin à la floraison, mais reste latent durant toute la période estivale pour reprendre son développement à la véraison, provoquant le pourrissement de la grappe. Certaines variétés, comme le Gamaret, sont résistantes à lattaque par Botrytis cinerea et dautres, comme le Gamay, y sont très sensibles. Ce phénomène de latence serait entre autre attribué à la production de phytoalexines par la vigne (resvératrol (1), pterostilbène (2) et e-viniférine (3)) inhibant le développement du champignon de juin à septembre. Le resvératrol et le pterostilbène font partie de la famille des stilbènes et sont des composés synthétisés par la plante suite à un stress. Ces molécules peuvent soxyder sous laction d
Botrytis is, in almost all cases bad for wine grapes. There is on very specific wine style that is can help, called Noble rot.. Firstly Noble Rot and Botrytis Bunch Rot in grapes are both caused by the same organism - Botrytis cinerea. Often in photographs both rots will look the same the difference being one is considered a problem the other a desirable trait!. Grapes are susceptible to this fungus as they ripen and produce sugar. Generally it causes a bunch rot that is bad for grape quality, it turns grapes mouldy, as mention above commonly known as Bunch Rot, Botrytis Rot or Grey Rot. It also creates conditions favorable for the growth of other nastiness like yeast, mould, and bacteria are we call secondary rots. These rots are even worse for grape quality with some being toxic! ...
The simultaneous suppression of the tomato fruit ripening-associated LePG and LeExp1 expression reduces susceptibility to B. cinerea infection during ripening, whereas suppression of LePG or LeExp1 alone does not reduce susceptibility, indicating that PG and Exp act cooperatively to support both softening (4, 22, 23, 29) and full pathogenicity of B. cinerea. The host CW is a primary target during B. cinerea growth on plant tissue (30). B. cinerea possesses a wide array of CWDEs (31, 32), including six PGs (33). B. cinerea mutants of either BcPG1 or BcPG2 resulted in significantly decreased virulence on multiple hosts, including tomato (5, 8). In addition, the ectopic expression of a potent PG-inhibiting protein (PGIP) from pear fruit (pPGIP) reduced the susceptibility of ripe tomato fruit to B. cinerea infection (6). Thus, the pathogens ability to efficiently disassemble the tomato fruit CW appears to be critical for full virulence. Although the pathogen apparently possesses the required tools ...

ENGLISH ABSTRACT: Various studies revealed that Botrytis cinerea, the causal pathogen of Botrytis bunch rot, is mostly associated with pedicels, rachises, laterals and berry bases, and not with berry skins as previously understood. Provided that sufficient coverage of inner bunch parts was achieved, laboratory studies have shown that fungicides can effectively reduce the amount of B. cinerea at the various positions in bunches, and prevent infection and symptom expression at all growth stages. The same efficacy was, however, not achieved with the same fungicides when using conventional spraying methods in vineyards. Poor disease control on fruit and leaves in vineyards is attributed to inappropriate timing of fungicide applications and/or insufficient coverage of susceptible tissue. Previously, spray coverage evaluations in South Africa were based on the use of water-sensitive cards. A variety of other methods have been used to assess spray coverage in vineyards, but none of these methods could ...
The signal peptides prediction algorithm SignalP v3.0, subcellular protein location prediction algorithm TargetP.v1.1, potential GPI-anchor sites prediction algorithm big-PI predictor, trans-membrane domains prediction algorithm TMHMM v2.0 and bioinformatics algorithm MEME were used to analyze 16446 protein sequences ofBotrytis cinerea. The results showed that there were 579 deduced secretary proteins. Among these proteins, the minimum and maximum of open read frame were 102 bp and 4848 bps respectively and mean score was 1271 bps. The signal peptides length was concentrated to 16~39 amino acids and the average length was 21. 122 of these proteins contain the highly conserved host-targeting-motif RxLx within 100 residues adjacent to the signal peptide cleavage site. According to PEDNAT and COG of GenBank database, this motifs functions include metabolism modification and cell secretion etc. We blast those putative secretary proteins with RxLx motif in GenBenk and found 47.54% of them have highly

Weve all enjoyed some delicious strawberries this summer, but a short-shelf life can limit that enjoyment. One of the biggest challenges in U.S. strawberry production is managing diseases and pests. The fungal pathogen Botrytis cinerea results in gray mold, or the unappetizing gray fuzz that can quickly appear on strawberries all too soon after we get them home. Growers typically apply fungicides on a weekly basis to control gray mold as well as other fungal diseases.. ...
Plants are exposed to many environmental stresses that affect their growth and development. These stresses include biotic stresses (via organisms) and abiotic stresses (via environment). Plants respond to these stresses by transcriptional reprogramming and different signaling pathways. Arabidopsis thaliana has shown great sensitivity to the biotic stress Botrytis cinerea. The WRKY33 gene plays an important role in plant defense mechanism against this pathogen. The overall goal is to identify common regulated genes of wrky33 mutant and 35S:WRKY33 over expressing transgenic lines in response to B. cinerea; ultimately to improve plant stress tolerance in Arabidopsis. The specific aims are to: (1) identify Arabidopsis regulated genes in response to B. cinerea infection; (2) determine common up- and down-regulated genes in response to B. cinerea infection in Arabidopsis wrky33 mutant and 35S:WRKY33 overexpression lines; and (3) characterize the function of the common genes in response to B. cinerea.

Botryotinia is a genus of ascomycete fungi causing several plant diseases. The anamorphs of Botryotinia are mostly included in the imperfect fungi genus Botrytis. The genus contains 22 species and one hybrid. Plant diseases caused by Botryotinia species appear primarily as blossom blights and fruit rots but also as leaf spots and bulb rots in the field and in stored products. The fungi induce host cell death resulting in progressive decay of infected plant tissue, whence they take nutrients. Sexual reproduction takes place with ascospores produced in apothecia, conidia are the means of asexual reproduction. Sclerotia of plano-convexoid shape are typical. Some species also cause damping off, killing seeds or seedlings during or before germination.

Another disease that takes tomato plants out fairly quickly is Botrytis or stem rot. The first sign of this disease is the plants look limp as if they need a drink of water. Starting at the top, most leaves have the drooping effect, which journeys down the plant. You can be fooled in the early stages of the disease as the plants seem to recover late in the day when the air cools at dusk. A careful inspection of the plant will reveal a darkened area around the trunk or branches of the plant. Another change will occur in that bumps or small knobs will appear on the trunk just above the area that is darkening. This is the tomato trying to send out aerial roots to save its life. The dark area is cutting off the flow of nutrients and moisture from the roots to the upper foliage. This area will rot right through and both top and root system will die. Sometimes there maybe laterals growing below this darkened area and these will be unaffected and will keep the roots supplied with energy. The rest of ...

Bethke G., Grundman R.E., Sreekanta S., Truman W., Katagiri F., Glazebrook J.. Pectins, major components of dicot cell walls, are synthesized in a heavily methylesterified form in the Golgi and are partially deesterified by pectin methylesterases (PMEs) upon export to the cell wall. PME activity is important for the virulence of the necrotrophic fungal pathogen Botrytis cinerea. Here, the roles of Arabidopsis PMEs in pattern-triggered immunity and immune responses to the necrotrophic fungus Alternaria brassicicola and the bacterial hemibiotroph Pseudomonas syringae pv maculicola ES4326 (Pma ES4326) were studied. Plant PME activity increased during pattern-triggered immunity and after inoculation with either pathogen. The increase of PME activity in response to pathogen treatment was concomitant with a decrease in pectin methylesterification. The pathogen-induced PME activity did not require salicylic acid or ethylene signaling, but was dependent on jasmonic acid signaling. In the case of ...

B. cinerea group I strains outside of Western Europe were collected in Hungary in 2008 from strawberry and rape plants. Sympatric . B. cinerea cryptic species were analyzed using a population genetic approach and phenotypic markers. Statistically significant, but moderate population differentiation was found between the two groups in Hungary. Group I was originally typified by the lack of the transposable elements Boty and Flipper. However, all the Hungarian group I isolates carried the Boty element and one isolate additionally contained Flipper, indicating a much wider genetic variation than ...

Forster, B.; Staub, T., 1996: Basis for use strategies of anilinopyrimidine and phenylpyrrole fungicides against Botrytis cinerea
Peat based growing media are not ecologically sustainable and often fail to support biological control. Miscanthus straw was (1) tested to partially replace peat; and (2) pre-colonized with a Trichoderma strain to increase the biological control capacity of the growing media. In two strawberry pot trials (denoted as experiment I & II), extruded and non-extruded miscanthus straw, with or without pre-colonization with T. harzianum T22, was used to partially (20% v/v) replace peat. We tested the performance of each mixture by monitoring strawberry plant development, nutrient content in the leaves and growing media, sensitivity of the fruit to the fungal pathogen Botrytis cinerea, rhizosphere community and strawberry defense responses. N immobilization by miscanthus straw reduced strawberry growth and yield in experiment II but not in I. The pre-colonization of the straw with Trichoderma increased the post-harvest disease suppressiveness against B. cinerea and changed the rhizosphere fungal microbiome in
The fungus Botrytis cinerea is an opportunistic pathogen on a wide variety of crops, causing disease known as grey mould through infections via wounds or dead plant parts. Synthetic fungicides for controlling this disease are fast becoming ineffective due to the development of resistance. This, coupled with consumers world wide becomng increasingly conscious of potential environment and health problems associated with the build up of toxic chemicals, (particularly in food products), have resulted in pressure to reduce the use of chemical pesticide volumes as well as its residues. An emerging alternative to random synthesis is the study and exploitation of naturally occurring products with fungicidal properties. There have been reports on the uses of synthetic fungicides for the control of plant pathogenic fungi. When utilized in two-way mixtures, such fungicides may maintain or enhance the level of control of a pathogen at reduced rates for both components utilized in combinations, or alone at ...
A rapid, simple and cost-effective test to detect and quantify fungicide resistant botrytis in a vineyard setting has been successfully demonstrated in Western Australia.
Botrytis blight is a very destructive disease caused by Botrytis spp., infecting flowers, trees, vegetables and fruits. Twelve new compounds were prepared by the reaction of potassium N-aryl-sulfonyldithiocarbimates with Morita-Baylis-Hillman derivatives bearing phenyl and furyl groups. These are the first examples of allyldithiocarbimate anions and were isolated as tetraphenylphosphonium salts. The new compounds were characterized by HRMS, NMR and Infrared spectroscopy. Further, the structures of three allyldithiocarbimates were determined by single crystal X-ray diffraction. The compounds are isostructural and crystallize in the space group P21/c of the monoclinic system, and the allyldithiocarbimate anions present Z configuration. All the compounds were active against Botrytis cinerea. The best results were achieved with the tetraphenylphosphonium (Z)-3-(furan-2-yl)-2-(methoxycarbonyl)allyl-(4-chlorophenylsulfonyl)dithiocarbimate (IC50 38 μM). ...
Glycolysis is the process of converting glucose into pyruvate and generating small amounts of ATP (energy) and NADH (reducing power). It is a central pathway that produces important precursor metabolites: six-carbon compounds of glucose-6P and fructose-6P and three-carbon compounds of glycerone-P, glyceraldehyde-3P, glycerate-3P, phosphoenolpyruvate, and pyruvate [MD:M00001]. Acetyl-CoA, another important precursor metabolite, is produced by oxidative decarboxylation of pyruvate [MD:M00307]. When the enzyme genes of this pathway are examined in completely sequenced genomes, the reaction steps of three-carbon compounds from glycerone-P to pyruvate form a conserved core module [MD:M00002], which is found in almost all organisms and which sometimes contains operon structures in bacterial genomes. Gluconeogenesis is a synthesis pathway of glucose from noncarbohydrate precursors. It is essentially a reversal of glycolysis with minor variations of alternative paths [MD:M00003 ...

Organic berry and fruit production suffers heavily from the lack of effective disease and pest management tools, and from inadequate insect pollination at times. As a consequence, the expanding demand on organic berries cannot be filled today. The BICOPOLL project aimed to change this and to improve the yield and quality of organic strawberry production significantly and thus farm economics. We used honeybees to (i) target deliver a biological control agent (fungus antagonist) to the flowers of the target crops (strawberries) to provide control of the problem diseases grey mold (Botrytis cinerea) and to (ii) improve the pollination of this organic horticultural crops. The use of bees has many environmental and economic benefits compared to spraying fungicide like in conventional farming systems. As bees, that actually forage in the target crop, is a key essential requirement for the entomovectoring technology, the main focus of this project was to determine, which factors can affect foraging ...

Transcription factor that binds specifically to the W box (5-(T)TGAC[CT]-3), a frequently occurring elicitor-responsive cis-acting element. Has a positive role in resistance to necrotrophic pathogens (e.g. Botrytis cinerea), but a negative effect on plant resistance to biotrophic pathogens (e.g. Pseudomonas syringae).
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
long before tasting and writing about them, but I wanted to see how a few years in the fridge would affect them. The examples in question are Dolce 2007, 06, 05 and 04, dessert wines in half-bottles, and what they reveal across four years is a remarkable and gratifying consistency in tone, structure, flavor profile and balance. Differences? Of course, and I will discuss those variations in more detail further in this post. The partners in Far Niente conceived of the project - a small winery devoted to a single dessert wine - in 1985; the first vintage introduced commercially was 1989, released in 1992. The production of dessert wine depends on geographical and climatic conditions - foggy, with a subtle balance between warm and cool - suitable for the inoculation of the botrytis mold, the noble rot, that can attack grapes, suck out the moisture and reduce them to concentrated sugar bombs. This invasion occurs grape by grape, not cluster by cluster, so harvesting a vineyard affected by botrytis ...

To date, almost all the pathogen effectors studied or discovered have been proteins, said lead author Hailing Jin, a professor of plant pathology and microbiology. Ours is the first study to add the RNA molecule to the list of effectors. We expect our work will help in the development of new means to control aggressive pathogens.. Small RNAs guide gene silencing in a wide range of eukaryotic organisms. In the case of Botrytis cinerea, small RNAs silence the expression of host defense genes, resulting in the host plant cells being less able to resist the fungal attack. The process is similar to how protein effectors weaken host immunity in the case of most pathogens.. What we have discovered is a naturally-occurring cross-kingdom RNAi phenomenon between a fungal pathogen and a plant host that serves as an advanced virulence mechanism, Jin said.. RNA interference or RNAi is a conserved gene regulatory mechanism that is guided by small RNAs for silencing (or suppressing) genes.. Next, Jin and ...
KENJA® 400 SC is a novel Group 7 fungicide for the control of Botrytis cinerea infecting Australian berry crops. Kenja works by inhibiting succinate dehydrogenase (SDH) production in the cell mitochondria.
Fungicide resistance is a growing problem, as evidenced by publication trends. Publications on this issue are particularly high across the worlds major economies, and many focus specifically on the fungus Botrytis.. A greater awareness of the toxic effects of conventional fungicide formulations is driving interest among those in the crop protection sector in new pesticides. Researchers are trying to increase efficacy with a more targeted approach for a specific organism or class of organisms, and by finding novel targets and modes of action to overcome resistance. With the goals of pesticide discovery not so very different from those of drug discovery, could insights from pharmaceutical research potentially help with the problem of fungicide resistance?. Some of us at Elsevier thought the answer to that question could be yes. Finding new lead compounds that might act as a new pesticide can be a lengthy process, and so we have been working on a method which can provide lead compounds by using ...

Sooty mold is often found on plants infested with sap sucking insects such as aphids, white flies, or scales which produce a sugary secretion called honeydew. This honeydew drips down onto leaves and branches providing a food base on which the sooty mold fungi can grow. Sooty mold may also grow on sap or resin associated with wounds.. We do not recommend control of the mold itself. However, the presence of sooty mold is often an indication of insect activity which has the potential for causing damage. Proper identification of the insect is necessary to determine if chemical control is warranted. Light coverings of the mold will gradually disappear during dry weather when its nutrient source is eliminated. Sooty mold can be physically washed off small plants if desired.. P440S. Revised by Chad Behrendt and Crystal Floyd 1999. ...
Snow Mold occurs when snow accumulates and then remains undisturbed for long periods on wet, unfrozen grass. This condition allows mold to germinate and spread in small patches throughout the lawn. Snow Mold is more prevalent in areas of greater snow accumulation, such as the edges of driveways and walks where snow is piled during shoveling and plowing. It also thrives in low-lying areas where moisture collects, as well as in other areas where snow takes longer to melt.. If you find Snow Mold on your lawn this spring, simply use a leaf rake to go over the affected areas to remove debris and stand the grass up to allow air to circulate. This alone is often enough for the grass to heal. Your first application of lawn fertilizer in the spring will also aid in the recovery process by helping your turf grow and push out the disease. In severe cases where raking and fertilizing fail the area may need to be reseeded.. ...
