The Cell Wall Integrity-Associated Map Kinase Homolog, AbSlt2 in the Necrotrophic fungus Alternaria brassicicola is Required for Pathogenicity of Brassicas
Using the genome database of the phytopathogenic fungus, Alternaria brassicicola, we identified a gene with high homology to the cell wall integrity-associated mitogen-activated protein (MAP) kinase, Slt2 in the yeast, Saccharomyces cerevisiae. This MAP kinase consists of a predicted 1,251-bp open …

Role of the COP9 Signalosome In Defense Responses In tomato
… by herbivorous insects and infection by a necrotrophic fungus.</p> <p>It has been shown previously in our lab that a MAP kinase signaling cascade is an essential part of systemin-mediated defense signaling and functions upstream of jasmonic acid biosynthesis. Co-silencing of <em>MPK1/2</em> …

Dissecting the molecular responses of Sorghum bicolor to Macrophomina phaseolina infection
Charcoal rot, caused by the necrotrophic fungus, Macrophomina phaseolina (Tassi) Goid., is an important disease in sorghum (Sorghum bicolor (L.) Moench). The molecular interactions between sorghum and M. phaseolina are poorly understood. In this study, a large-scale RNA-Seq experiment and four …

Investigations on the role of mitogen-activated protein kinases 11 and 17 in defense response of Arabidopsis thaliana
… response against Pseudomonas syringae and the necrotrophic fungus Botrytis cinerea, whereas I could reveal a slight reduction in basal defense against the biotrophic oomycete Hyaloperonospora arabidopsidis. In addition, I showed that both mutants are not affected in the production of reactive …

Untersuchungen zu Monolignolbiosynthese-Mutanten und den CCR Genen in Arabidopsis thaliana
… DC3000 (virulent and avirulent strains), the necrotrophic fungus Alternaria brassicicola and the non-host obligate biotroph Blumeria graminis f. sp. hordei with mutant plants was investigated microscopically and compared to wild type plants. The control and localization of the expression of …

Genotypic characterization and fungicide resistance monitoring for Virginia populations of Parastagonospora nodorum in wheat
… wheat in the mid-Atlantic U.S., is caused by the necrotrophic fungus Parastagonospora nodorum. SNB is managed using cultural practices, resistant varieties, and foliar fungicides. There are increasing trends of severity and incidence of SNB in Virginia and the surrounding mid-Atlantic region, but …

Genomic selection for glume blotch resistance and milling and baking quality traits in soft red winter wheat
… quality and quantity of the wheat crop annually. Necrotrophic fungus Parastagonospora nodorum (syn. Stagonospora nodorum, Septoria nodorum) is a leading fungal threat to wheat production in humid regions. A P. nodorum infection results in leaf blotch and glume blotch in wheat and related grass …

The study of transcriptional regulation of necrotrophic effector genes ToxA and Tox3 in the wheat pathogen Parastagonospora nodorum
… nodorum (P. nodorum) is an important necrotrophic fungus on wheat causing significant yield losses in Australia per annum. It is now widely recognized that P. nodorum causes disease by secreting necrotrophic effectors (NEs) which induce necrosis on susceptible wheat leaves through an …

Transcriptomic characterization of soybean – sclerotinia sclerotiorum interaction at early infection stages
… is speculated that, because S. sclerotiorum is a necrotrophic fungus that feeds on dead host cells, inhibiting host cell death could slow down its infection. Our expression data also identified six membrane trafficking-related genes that were proposed to contribute to negative regulation of PCD …

Key roles of glutamate metabolism and cuticle permeability in the multifaceted defense response of the abscisic acid deficient sitiens tomato mutant against Botrytis cinerea
… exhibit an early biotrophic phase followed by a necrotrophic lifestyle in later stages of infection. Moreover, necrotrophic pathogens have been further categorized into two major groups based on their host specificity/range, as host-specific necrotrophs, and broad-host range necrotrophs. Studying …

The role of abscisic acid in the defence response of tomato (Solanum lycopersicum) to the necrotrophic pathogens Botrytis cinerea and Erwinia chrysanthemi
… results in increased resistance towards the necrotrophic fungus Botrytis cinerea and the necrotrophic bacterium Erwinia chrysanthemi, two pathogens for which the occurrence of resistance is very rare. Comparison of gene expression in sitiens and wild-type tomato with TOM1 microarrays revealed …
