Cell death in sscd1 is accompanied by the up-regulation of JA-inducible genes and the accumulation of jasmonic acid. (a–c) Relative expression level of JA -inducible genes VSP2 (a), PDF1.2 (b), THI2.1 (c) in wild-type (WT) and sscd1 seedlings that were grown under LD for 3 weeks, and then transferred to SD for 0, 1, 2 and 3 days. (d) The content of jasmonic acid in wild-type (WT) and sscd1 seedlings that were grown under LD for 3 weeks, and then transferred to SD for 0, 2 and 3 days. LD, long day; SD, short day. The expression of genes was analyzed by RT-qPCR, relative expression level was normalized to those of ACTIN2 and the control (in wild type) was set to 1. Mean ± SE from three biological replicates. Asterisk * and ** represent the significance of differences (two-tailed Student’s t-test) at the levels of P < 0.05 and P < 0.01, respectively.
