Project description:The deficiency of Jasmonic Acid Oxidase 2 (JAO2) disrupts a metabolic sink in jasmonate hormonal pathway. Consequently, higher flux towards hormone JA-Ile is observed and some leaf JA responses have elevated basal levels relative to wild-type (WT) leaves. We report the compared transcriptomes of WT and jao2-1 rosette leaves, before and 48h after inoculation with spores of the fungus Botrytis cinerea. The study reveals the set of jao2-deregulated genes before infection

Project description:The Arabidopsis thaliana mutant wrky33 is highly susceptible to the necrotrophic fungus Botrytis cinerea. We identified by ChIP-seq >1680 high-confidence WRKY33 binding sites associated with 1576 genes within the Arabidopsis genome, with all of them being dependent on rapid activation of WRKY33 expression by Botrytis cinerea strain 2100. Genome-wide transcriptional analysis defined 318 genes as direct functional targets at 14 h post inoculation. Comparison between resistant wild-type Columbia-0 and susceptible wrky33 mutant plants revealed that expression of 75% of all WRKY33 regulated targets were down-regulated upon infection, indicating that WRKY33 predominately acts as a repressor. However, WRKY33 appears to possess dual functionality acting either as a repressor or as an activator in a promoter-context dependent manner. Our genome-wide analysis confirmed known WRKY33 targets involved in ethylene and jasmonic acid hormone signaling and phytoalexin biosynthesis, but also uncovered a previously unknown role of abscisic acid (ABA) biosynthesis in the complex regulatory circuitry affecting resistance towards Botrytis.

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.

Project description:af13_plp2 - plp2 botrytis cinerea 2 - Effects of deregulation of a lipid acyl hydrolase gene (PLP2, At2g26560) on global transcriptome upon infection by Botrytis cinerea. This deregulation affects resistance levels against fungal and bacterial pathogens, likely by perturbing the biosynthesis of oxylipins. Oxylipins are fatty acid-derived compounds (example:jasmonic acid) with diverse signaling or antimicrobial properties. - 5000 spores of Botrytis were pipetted on 4 infection sites per ault leaf. Leaf material was harvested at 0 and 2 days later. 3 plant genotypes were used (Col-0 ecotype): siPLP2 (RNAi-silenced),pBIN (empty pBIN-transformed),PLP2OE (PLP2-overexpressors).

Project description:Spores of Bacillales and Clostridiales species contain 100s of different mRNAs, and their major function in Bacillus subtilis is to provide ribonucleotides for new RNA synthesis when spores germinate. In new work, RNA was isolated from spores of five Bacillales and one Clostridioides species and relative spore mRNA levels were determined by RNA-seq. Determination of RNA levels in single spores allowed calculation of RNA nt/spore, and assuming mRNA is 3% of spore RNA allowed calculation that only ~6% of spore mRNAs were present at ≥ 1/spore. Bacillus subtilis, Bacillus atrophaeus and Clostridioides difficile spores had 49, 42 and 51 mRNAs at >1/spore, respectively. Numbers of mRNAs at ≥1/spore were ~10 to 50% higher in Geobacillus stearothermophilus and Bacillus thuringiensis Al Hakam spores, respectively, and ~ 4-fold higher in Bacillus megaterium spores. Notably, in all species: i) many of the 60 most abundant spore mRNAs were transcribed by RNA polymerase with forespore-specific s factors; ii) some to many of the most abundant spore mRNAs encoded orthologs of those encoded by abundant B. subtilis spore mRNAs and proteins present in dormant spores ; and iii) some spore mRNAs were likely transcribed in the mother cell compartment of the sporulating cell. Indeed , analysis of the coverage of RNA-seq reads on mRNAs from all six species suggested that abundant spore mRNAs were at least somewhat fragmented. This observation was confirmed by RT-qPCR analysis of three abundant mRNAs each from B. subtilis and C. difficile spores. These data add to a growing body of evidence indicating that the great majority of mRNAs in spores of Firmicutes are degradation and function as a ribonucleotide depot for new RNA synthesis when spores germinate.
