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:Current protection strategies against the fungal pathogen Botrytis cinerea rely on a combination of conventional fungicides and host genetic resistance. Defence elicitors can stimulate plant defence mechanisms through a phenomenon known as priming. Priming results on a faster and/or stronger expression of resistance upon pathogen attack. This work aims to study priming of a commercial formulation of the elicitor Chitosan. Treatments with Chitosan result in induced resistance in solanaceous and brassicaceous plants. Large-scale transcriptomic analysis in this study revealed that Chitosan primes gene expression at early time-points after infection. Four conditions were analysed using microarrays: (i) water-treated and non-infected plants (Water + Mock); (ii) Chitosan-treated and non-infected plants (Chitosan + Mock); (iii) water-treated and B. cinerea-infected plants (Water + B. cinerea); (iv) Chitosan-treated and B. cinerea-infected plants (Chitosan + B. cinerea). Inoculations were performed four days after treatment with Chitosan, and leaf discs from four independent plants (biological replicates) per treatment were sampled at 6 h, 9 h and 12 h post-inoculation (hpi) with water mock or B. cinerea spores.

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:Botrytis cinerea is a model phytopathogenic fungus that infects more than 200 different relevant crops, thus being classified among the top ten fungal plant diseases. B. cinerea exhibits a wide arsenal of tools to infect plant tissues. Most of these factors are related to signal transduction cascades, in which membrane proteins play a key role as a bridge between environmental conditions and intracellular molecular processes. This work describes the first proteomic approach to study the membranome of B. cinerea under different pathogenicity condition induced by using different plant-based elicitors: Glucose and Tomato Cell Wall (TCW). A discovery proteomics analysis of membrane protein extracts was carried out by mass spectrometry. A total of 2,794 proteins were successfully identified, and approximately 46% of them could be classified as membrane proteins based on the presence of transmembrane regions and covalent post-translational modifications. Further analyses showed significant differences in the fungal membranome composition depending on the available carbon source: 804 proteins were exclusively identified when the fungus was cultured in the presence of glucose as sole carbon source, and 251 proteins were exclusively identified in the presence of TCW. Besides, among the 1737 common proteins, a subset of 898 proteins presented clear differences in their abundance and in order to clarify the specific changes produced in the membranome, proteins were categorized according to their gene ontology annotation shown different profiles. As a result of this work, we present here the first description of the membranome of B. cinerea, which will certainly provide a better understanding of this important subproteome in B. cinerea.

Project description:Fruit taste is determined by sugars, acids and in some species, bitter chemicals. Attraction of seed-dispersing organisms in nature and breeding for consumer preferences requires reduced fruit bitterness. A key metabolic shift during ripening prevents tomato fruit bitterness by eliminating α-tomatine, a renowned defence-associated Solanum alkaloid. Here, we combined fine mapping with information from 150 re-sequenced genomes and genotyping a 650 tomato core collection to identify nine bitter-tasting accessions including the ‘high α-tomatine’ Peruvian landraces reported by Rick and colleagues (1994). These ‘bitter’ accessions contain a deletion in GORKY, a nitrate/peptide family (NPF) transporter mediating α-tomatine subcellular localization during fruit ripening. GORKY exports α-tomatine and its derivatives from the vacuole to the cytosol and this facilitates the conversion of the entire α-tomatine pool to non-bitter forms, rendering the fruit palatable. Hence, GORKY activity was a significant innovation in the process of tomato fruit domestication and breeding. The experiment was carried out to further prove that GORKY is localized to tonoplast in ripe fruit.

Project description:Transcriptomic analysis in response to Botrytis cinerea infections under conrasting nitrate regime Nitrogen (N) is one of the main limiting nutrients for plant growth and crop yield. It is well documented that changes in nitrate availability, the main N source found in agricultural soils, influences a myriad of developmental programs and processes including the plant defense response. Indeed, many agronomical reports indicate that the plant N nutritional status influences their ability to respond effectively when challenged by different pathogens. However, the molecular mechanisms involved in N-modulation of plant susceptibility to pathogens are poorly characterized. In this work, we show that Solanum lycopersicum defense response to the necrotrophic fungus Botrytis cinerea is affected by plant N availability, with higher susceptibility in nitrate-limiting conditions. Global gene expression responses of tomato against B. cinerea under contrasting nitrate conditions reveals that plant primary metabolism is affected by the fungal infection regardless of N regimes. This result suggests that differential susceptibility to pathogen attack under contrasting N conditions is not only explained by a metabolic alteration. We used a systems biology approach to identify the transcriptional regulatory network implicated in plant response to the fungus infection under contrasting nitrate conditions. Interestingly, hub genes in this network are known key transcription factors involved in ethylene and jasmonic acid signaling. This result positions these hormones as key integrators of nitrate and defense against B. cinerea in tomato plants. Our results provide insights into potential crosstalk mechanisms between necrotrophic defense response and N status in plants. To better understand the molecular changes underlying the impact of nitrate availability on plant susceptibility to B. cinerea, we performed plant transcriptome profiling assays on mock-treated (3 biological replicates) and infected plants ( 3 biological replicates) grown under three N conditions, using GeneChip Tomato Genome Arrays (Affymetrix).
