Priming resistance of tomato to Botrytis cinerea infection by root drench treatment with beta-aminobutyric acid.. Priming resistance of tomato to Botrytis cinerea infection by root drench treatment with beta-aminobutyric acid.

Induced resistance responses of plants to biotic stress can be enhanced by prior treatment by chemical priming agents such as beta-aminobutyric acid (BABA). Defence-related genes are typically not expressed following priming, but show faster and/or stronger induced expression following infection. Here we test the transcriptome responses of control and BABA-primed plants to infection with the fungal pathogen Botrytis cinerea. Overall design: Tomato leaves from control and primed plants were either mock inoculated or inolculated with Botrytis spores. Leaves were harvested immediately (time zero) and at 6, 9 and 12 hours following inoculation.
