Project description:This SuperSeries is composed of the following subset Series: GSE29642: Arabidopsis defense against Botrytis cinerea: chronology and regulation deciphered by high-resolution temporal transcriptomic analysis (time series) GSE39597: Arabidopsis defense against Botrytis cinerea: chronology and regulation deciphered by high-resolution temporal transcriptomic analysis (tga3-2 knockout data) Refer to individual Series
Project description:Next generation sequencing was performed to identify genes changed in Arabidopsis thaliana upon Botrytis cinerea infection. The goal of the work is to find interesting genes involved in plant defense. The object is to reveal the molecular mechanism of plant defense.
Project description:Two samples from a larger study of the effect of Botrytis cinerea infection on gene expression in Arabidopsis thaliana. These two samples also form part of an investigation of the sequence dependancy of DNA and RNA fragmentation within ChIP-seq and RNA-seq experiments
Project description:Transcriptional profiling of Arabidopsis leaves comparing mock-treated leaves with Botrytis cinerea infected leaves over a time-course (12 and 24 hrs).
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:Arabidopsis thaliana exhibits differential susceptibility to the fungal pathogen Botrytis cinerea depending on the time of day that infection occurs. We hypothesised that this is driven by teh circadian clock and that differences in the amplitude or speed of the plant defence response will underlie the difference in susceptiblity. A major component of the defence response is transcriptional reprogramming, hence we investigated whether the transcriptional response to B. cinerea infection differs following inoculation at subjective dawn or night (the points of greatest difference in susceptiblity) under constant light conditions.
