Resistance to Botrytis cinerea conferred by altered HG is suppressed by exogenous ABA. Rosette leaves of five-week-old WT, PG, qua2, and tsd2-1 plants were treated with 0.01% MeOH (white bars) or 100μm ABA (grey bars) and, after 24h, inoculated with a B. cinerea spore suspension. Lesion area was measured 2days after inoculation (n > 10 lesions for each genotype). Bars indicate average lesion area ± SE. Different letters indicate statistically significant differences, according to two-way ANOVA followed by Tukey’s significance test (p < 0.05). This experiment was repeated three times with similar results.
