  • AtCLH1 RNAi silenced, AtCLH1 overexpression, and vector control plants were inoculated with E. carotovora in normal light (200 to 250 μmol m−2 s−1 photons) or low light (50 μmol m−2 s−1 photons). In another experiment, plants were inoculated with E. carotovora in darkness and transferred to high light (900 μmol m−2 s−1 photons) 14 h after this. Percentage ± sd of leaves completely macerated after 3 d was calculated from three independent experiments with 10 to 30 individual leaves. Different letters (in bold) indicate significant differences (P< 0.05) calculated with one-way ANOVA followed by Tukey HSD test. n.t., Not tested.
