Transcriptomic comparison of Botrytis cinerea wild type and VELVET mutants

Project description:An RNAseq-based transcriptomic comparison of Botrytis cinerea wild type and the three VELVET mutants was performed, to correlate common virulence defects of the mutants with changes in gene expression. A large number of genes encoding infection-related and secreted proteins was strongly underexpressed in the mutants, in particular genes encoding proteases and carbohydrate active enzymes. Many VELVET-regulated genes were found to be upregulated in the wild type during host plant infection (Müller et al.: Investigations on VELVET regulatory mutants confirm the role of host tissue acidification and secretion of proteins in pathogenesis of Botrytis cinerea; New Phytologist, 2018)

The VELVET complex in the gray mold fungus Botrytis cinerea: impact of BcLAE1 on differentiation, secondary metabolism and virulence

Project description:Full transcriptomes of the Botrytis cinerea wild-type strain B0510 and the null-mutants deltaBcVEL1 and deltaBcLAE1, cultured onto solid grape juice medium with cellophane overlays , were compared to identify BcVEL1 or/and BcLAE1-dependent genes. The Botrytis cinerea wild-type strain and the null-mutants deltaBcVEL1 and BcLAE1 were cultured for 48h onto solid grape juice medium with cellophane overlays. 4 replicates were performed. The 12 total-RNA samples (3 strains* 4 replicates) were used for hybridization on NimbleGen 4plex gene expression arrays (20,885 gene models from Botrytis cinerea with three 60-mer probes per gene).

WRKY33-dependent expression of Arabidopsis genes upon Botrytis cinerea 2100 inoculation

Project description:The Arabidopsis thaliana mutant wrky33 is highly susceptible to the necrotrophic fungus Botrytis cinerea. Comparing the expression profiles of B. cinerea-infected wrky33 and WT plants we identified 2765 differentially expressed genes dependent on WRKY33, of which 1675 were up-regulated in the mutant (termed WRKY33-repressed genes) and 1090 were down-regulated in the mutant. Combined with ChIP-seq data 318 genes were identified as direct functional targets of WRKY33 at 14 h post inoculation with spores of Botrytis cinerea 2100.

Expression data of tomato fruit responses to Botrytis cinerea

Project description:Tomato fruit ripening is associated with a dramatic increase in susceptibility to the fungal pathogen Botrytis cinerea, the causal agent of gray mold. Mature green fruit, prior to ripening, are largely resistant to B. cinerea, whereas red fruit, at the end of ripening, are susceptible to B. cinerea infection. We used microarrays to detail the gene expression changes that are induced by B. cinerea when tomato fruit at unripe and ripe stages are infected. Keywords: plant responses to pathogens

Effect of depletion of NUP62 on gene expression during Botrytis cinerea infection of Arabidopsis seedlings [Arabidopsis]

Project description:To investigate NUP62 in the regulation of plant defense against Botrytis cinerea , we performed gene expression profiling analysis using data obtained from RNA-seq of nup62 mutant and WT arabidopsis with or without Botrytis cinerea infection.
