Tomato Gene Expression Under Chitosan Priming Against Botrytis cinerea

Daniel De Vega from the James Hutton Institute conducted transcriptomic analysis of tomato plants treated with the elicitor chitosan to study defense priming against the fungal pathogen Botrytis cinerea. The work identified two novel tomato genes, Avr9/Cf-9 rapidly-elicited protein 75 (ACRE75) and 180 (ACRE180), as positive regulators of resistance. This dataset likely contains gene expression profiles from large-scale transcriptomic analysis at early time-points after infection.

Use Cases

• Identify genes primed by chitosan treatment based on transcriptomic analysis.
• Study the role of ACRE75 and ACRE180 homologs in plant resistance based on overexpression experiments.
• Analyze the link between callose deposition, jasmonic acid accumulation, and enhanced resistance described in the study.
• Model plant defense priming mechanisms in Solanaceae and Brassicaceae plants against Botrytis cinerea.

Strengths

• Dataset is derived from large-scale transcriptomic analysis, suggesting a substantial volume of gene expression data.
• Research identifies specific novel genes (ACRE75 and ACRE180) with validated roles in resistance through transient and stable overexpression.
• Study links chitosan priming to concrete physiological responses like callose deposition and jasmonic acid accumulation.
