Project description:Two long serial analysis of gene expression (LongSAGE) libraries of germinating conidia of Botrytis cinerea were generated with and without resveratrol treatments for unraveling the antifungal mechanisms of this phytoalexin by global transcriptome analysis – 82,786 total tags and a minimum of 15,665 unitags were obtained respectively. By tag-to-gene mapping, about 55% of the total unitags were matched to known genes. There were 109 unitags that showed significant differences in the two LongSAGE libraries, corresponding to 43 up- and 44 down-regulated genes, and 22 unmatched unitags as new gene candidates. These results showed that resveratrol inhibited expression of genes related to the glycolysis-Krebs cycle and mitochondrial electron transport chains at multiple sites in conidia germination, with induction of modified Entner–Doudoroff pathway as metabolic compensation. The chaperone-mediated protein folding and ubiquitin proteolysis systems were inhibited, while detoxification of resveratrol via ABC transporters was activated in this fungal pathogen.

Project description:Investigation of whole genome gene expression level changes in Botrytis cinerea wild type conidia during germination in comparison to the bmp1 MAP kinase deletion mutant.
Project description:Investigation of whole genome gene expression level changes in Botrytis cinerea wild type conidia during germination in comparison to the bmp1 MAP kinase deletion mutant. A 18 chip study using total RNA recovered from four different time points for the wild-type and one time point for the bmp1 deletion mutant. Each time point was analyzed with three biological replicates. Expression level of 20,885 genes from Botrytis cinerea strain B05.10 and T4 with three 60mer probes per gene was analysed.
Project description:Analysis of the genome-wide DNA methylation pattern of Botrytis cinerea. Results provide new and important information that DNA methylation is critical for pathogenicity and development of Botrytis cinerea by regulating gene expression.

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.
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. Experiment Overall Design: Tomato fruit at mature green and red ripe stages were wound inoculated with a water suspension of B. cinerea conidia. Twenty four hours post inoculation fruit pericarp and epicarp tissue around and including the inoculation sites was collected and the total RNA extracted. Total RNA was also collected from healthy and mock inoculated fruit.
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. Comparison of altered gene expression in Arabidopsis WT and wrky33 mutant plants 14 hours post inoculation with Botrytis cinerea 2100.
Project description:To screen Botrytis genes activated in infection process, we performed gene expression profiling analysis using data obtained from RNA-seq of Botrytis cinerea cultured in vitro or infecting Arabidopsis leaves.
