Gadolinium protects Arabidopsis thaliana against Botrytis cinerea through the activation of JA/ET-induced defense responses

Project description:Plant food production is severely affected by fungi; to cope with this problem, farmers use synthetic fungicides. However, the need to reduce fungicide application has led to a search for alternatives, such as biostimulants. Rare-earth elements (REEs) are widely used as biostimulants, but their mode of action and their potential as an alternative to synthetic fungicides have not been fully studied. Here, the biostimulant effect of gadolinium (Gd) is explored using the plant-pathosystem Arabidopsis thaliana–Botrytis cinerea . We determine that Gd induces local, systemic, and long-lasting plant defense responses to B. cinerea, without affecting fungal development. The physiological changes induced by Gd have been related to its structural resemblance to calcium. However, our results show that the calcium-induced defense response is not sufficient to protect plants against B. cinerea, compared to Gd. Furthermore, a genome-wide transcriptomic analysis shows that Gd induces plant defenses and modifies early and late defense responses. However, the resistance to B. cinerea is dependent on JA/ET-induced responses. These data support the conclusion that Gd can be used as a biocontrol agent for B. cinerea. These results are a valuable tool to uncover the molecular mechanisms induced by REEs.

Analysis of the function of the Arabidopsis DRL1 gene in Botrytis cinerea-induced transcriptome changes

Project description:To define how DRL1 regulates Botrytis cinerea-induced transcriptional changes at the genome level, we performed a microarray experiment on B. cinerea-infected drl1 and wild-type plants to identify genes that were differentially expressed between drl1 and the wild type. A total of 200 defense response genes were differentially expressed between drl1 and the wild type at six hours post-inoculation. These genes include 20 ethylene (ET) responsive genes, 23 jasmonic acid (JA)/ET responsive genes, 50 JA responsive genes, and 107 other defense genes. All ET and JA/ET responsive genes and majorities of JA responsive and other defense genes were down-regulated in the drl1 mutant. Among the down-regulated genes are a group of well-characterized defense genes, including ORA59, ERF1, WRKY33, SIB1, PAD3, GLIP1, and CYP79B2, which have been demonstrated to function in resistance to necrotrophic fungal pathogens, indicating that DLR1 may contribute to B. cinerea resistance by modulating the expression of these defense genes.

Analysis of the molecular dialogue between gray mold (Botrytis cinerea) and grapevine (Vitis vinifera) reveals a clear shift in defense mechanisms during berry ripening

Project description:Mature grapevine berries at the harvesting stage (MB) are very susceptible to the gray mold fungus Botrytis cinerea while veraison berries (VB) are not. We conducted simultaneous microscopic and transcriptomic analyses of the pathogen and the host to investigate the infectious process developed by B. cinerea on MB versus VB, and the plant defense mechanisms deployed to stop the fungus development. On the pathogen side, our genome-wide transcriptomic data revealed that B. cinerea genes up-regulated during infection of MB are enriched in functional categories related to necrotrophy such as degradation of plant cell wall, proteolysis, membrane transport, reactive oxygen species generation and detoxification. Quantitative-PCR on a set of representative genes related to virulence and microscopic observations further demonstrated that the infection is also initiated on VB but stops at the penetration stage. On the plant side, genome-wide transcriptomic analysis and metabolic data revealed a defense pathways switch during berry ripening. In response to B. cinerea infection, VB activated a burst of reactive oxygen species (ROS), the salicylate (SA)-dependent defense pathway, the synthesis of the resveratrol phytoalexin and cell-wall strengthening. In opposite, infected MB activated the jasmonate (JA)-dependent pathway which does not stop the fungal necrotrophic process. Grapevine berries at veraison (VB) and harvesting stages (MB) were inoculated with Botrytis cinerea B05-10 and samples were taken at 24h and 48h post-inoculation. An additional uninfected control sample taken at 0h post-inoculation was included in the experimental design. 3 replicates per sample were performed. The total-RNA samples were labeled and used for hybridization on NimbleGen 12plex Vitis vinifera gene expression array.

Functional analysis of lipid acyl hydrolases in Arabidopsis antimicrobial defense: plp2 Botrytis cinerea

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).
