Arabidopsis displays clock‐modulated susceptibility to Botrytis cinerea. Detached leaves from 4‐week‐old plants were inoculated with B. cinerea spores at CT24 (subjective dawn, white bars) or CT42 (subjective night, grey bars) under LL conditions, and lesion size measured at 72 hpi. Data shown are mean values ± standard error of the mean (SEM) from six (Col‐0 and elf3‐1) or three (Ws‐2 and cca1 lhy) independent experiments. Twenty leaves were inoculated per genotype/time of inoculation combination in each experiment. anova revealed a significant effect of both host genotype (P < 0.001) and time of inoculation (P < 0.001) on lesion size. ^a–cMean lesion sizes with different letters are significantly different (P < 0.01) as determined by Fisher LSD post‐hoc analysis.
