SUMMARY Sclerotinia sclerotiorum (Lib.) de Bary is a necrotrophic fungal pathogen causing disease in wide range of plants. This review summarizes current knowledge mechanisms employed by the fungus to parasitize its host with emphasis on biology, physiology and molecular aspects pathogenicity. In addition, tools for research strategies combat S. are discussed.Sclerotinia Bary: kingdom Fungi, phylum Ascomycota, class Discomycetes, order Helotiales, family Sclerotiniaceae, genus...
Fungal plant pathogens secrete effector molecules to establish disease on their hosts, and plants in turn use immune receptors try intercept these effectors. The tomato receptor Ve1 governs resistance race 1 strains of the soil-borne vascular wilt fungi Verticillium dahliae albo-atrum, but corresponding remained unknown thus far. By high-throughput population genome sequencing, a single 50-Kb sequence stretch was identified that only occurs strains, subsequent transcriptome sequencing...
Sexual recombination drives genetic diversity in eukaryotic genomes and fosters adaptation to novel environmental challenges. Although strictly asexual microorganisms are often considered as evolutionary dead ends, they comprise many devastating plant pathogens. Presently, it remains unknown how such pathogens generate the variation that is required for quick evolution arms race with their hosts. Here, we show extensive chromosomal rearrangements pathogenic fungus Verticillium dahliae...
Summary During tomato leaf colonization, the biotrophic fungus Cladosporium fulvum secretes several effector proteins into apoplast. Eight effectors have previously been characterized and show no significant homology to each other or fungal genes. To discover novel C. that might play a role in virulence, we utilized two‐dimensional polyacrylamide gel electrophoresis (2D‐PAGE) visualize secreted during –tomato interactions. Three were identified: CfPhiA, Ecp6 Ecp7. CfPhiA shows found on...
Abstract Cladosporium fulvum (syn. Passalora fulva) is a biotrophic fungal pathogen that causes leaf mold of tomato (Solanum lycopersicum). During growth in the apoplast, fungus establishes disease by secreting effector proteins, 10 which have been characterized. We previously shown Avr2 interacts with apoplastic Cys protease Rcr3, required for Cf-2–mediated immunity. now show genuine virulence factor C. fulvum. Heterologous expression Arabidopsis thaliana enhanced susceptibility toward...
The biotrophic fungal pathogen Cladosporium fulvum (syn. Passalora fulva) is the causal agent of tomato leaf mold. Avr4 protein belongs to a set effectors that secreted by C. during infection and thought play role in virulence. Previous studies have shown binds chitin present cell walls that, through this binding, can protect these against hydrolysis plant chitinases. In study, we demonstrate expression Arabidopsis results increased virulence several pathogens with exposed their walls,...
Abstract Cercospora leaf spot, caused by the fungal pathogen beticola , is most destructive foliar disease of sugar beet worldwide. This review discusses C. genetics, genomics, and biology summarizes our current understanding molecular interactions that occur between its host. We highlight known virulence arsenal as well ability to overcome currently used management strategies. Finally, we discuss future prospects for study infections in context newly employed tools uncover additional...
The wheat gene Lr34 confers partial resistance to all races of Puccinia triticina, the causal agent leaf rust. However, biological basis for exceptional durability is unclear. We used Affymetrix GeneChip Wheat Genome Array compare transcriptional changes near-isogenic lines Thatcher in a compatible interaction, an incompatible interaction conferred by Lr1, and race-nonspecific response conditioned 3 7 days postinoculation (dpi) with P. triticina. No differentially expressed genes were...
Cercospora leaf spot (CLS), caused by the fungus beticola, is most serious foliar disease of sugar beet (Beta vulgaris L.) worldwide. Disease control mainly achieved timely fungicide applications. In 2011, CLS failures were reported in spite application quinone outside inhibitor (QoI) several counties Michigan, United States. The purpose this study was to confirm resistant phenotype and identify molecular basis for QoI resistance Michigan C. beticola isolates.Isolates collected 1998 1999...
Rhizoctonia solani AG-2-2 is the causal agent of root and crown rot in sugar beet; however, recent increases disease incidence severity were grounds to reevaluate this pathosystem. To assess capacity at which other anastomosis groups (AGs) are able infect beet, 15 AGs intraspecific (ISGs) tested for pathogenicity on resistant ('FC708 CMS') susceptible ('Monohikari') seedlings 10-week-old plants. Several ISGs pathogenic regardless host resistance but only IIIB IV caused significant Because...
Early blight, caused by Alternaria solani, is an economically important foliar disease of potato in several production areas the United States. Few cultivars possess resistance to early blight; therefore, application fungicides primary means achieving control. Previous work our laboratory reported succinate dehydrogenase-inhibiting (SDHI) fungicide boscalid this plant pathogen with a concomitant loss Two phenotypes were detected, one which A. solani isolates moderately resistant boscalid,...
Significance Species in the fungal genus Cercospora cause diseases many important crops worldwide. Their success as pathogens is largely due to secretion of cercosporin during infection. We report that toxin biosynthesis ( CTB ) gene cluster ancient and was horizontally transferred diverse plant pathogens. Because our analyses revealed genes adjacent established with similar evolutionary trajectories, we evaluated their role beticola show four are necessary for biosynthesis. Lastly,...
The hemibiotrophic fungus Cercospora beticola causes leaf spot of sugar beet. Leaf control measures include the application sterol demethylation inhibitor (DMI) fungicides. However, reduced sensitivity to DMIs has been reported recently in Red River Valley beet-growing region North Dakota and Minnesota. Here, we report cloning molecular characterization CbCyp51, which encodes DMI target enzyme P450 14α-demethylase C. beticola. CbCyp51 is a 1,632-bp intron-free gene with obvious homology...
Vascular wilts caused by Verticillium spp. are destructive plant diseases affecting hundreds of hosts. Only a few causal agents vascular wilt diseases, which V. dahliae is the most notorious pathogen, and several genomes available. In contrast, tricorpus mainly known as saprophyte agent opportunistic infections. Based on hybrid approach that combines second third generation sequencing, near-gapless genome assembly was obtained. With comparative genomics, we sought to identify genomic...
Rhizomania is a disease of sugarbeet caused by beet necrotic yellow vein virus (BNYVV) that significantly affects yield globally. Accurate and sensitive detection methods for BNYVV in plants field soil are necessary growers to make informed decisions on variety selection manage this disease. A recently developed CRISPR-Cas-based method has proven highly accurate human diagnostics. Here, we report the development CRISPR-Cas12a-based detecting roots sugarbeet. critical aspect technique...
