COP1 increases the lesions inflicted by B. cinerea under SD, whereas LD reduces COP1 nuclear abundance. A, Nuclear abundance of YFP-COP1 at the end of the first photoperiod under LD and in SD controls. Data are means ± se of eight to nine plant replicates and representative images (arrows point to nuclei with detectable YFP-COP1). Bars = 20 μm. B, Resistance to B. cinerea in cop1 mutants and the COP1 overexpressor (COP1-OX) under SD and LD represented by relative lesion size. Data are means ± se of 13 plant replicates. Different letters indicate significant differences (P < 0.05) determined using Student’s t test (A) or Bonferroni posthoc tests (B). WT, Wild type.
