Expression levels of Botrytis cinerea- and other stress-regulated genes in response to B. cinerea treatment. Relative expression levels obtained by qRT-PCR for selected top 15 common up- and down-regulated genes across all stresses in response to B. cinerea infection at 18 hpi (Table 2). Gene expression in Arabidopsis wild-type plants inoculated with B. cinerea at 18 hpi were compared to non-inoculated samples (0 hpi) and normalized to the expression of the control gene, Arabidopsis Actin2 (AtActin2). Error bars for qRT-PCR values are standard errors (n = 3). hpi, hours post inoculation.
