SA, EDS1, and PAD4 are required for the expression of SRGs in the var2-9 mutant. Five-day-old wild-type (WT), var2-9, var2-9 cpNahG (v2/N), var2-9 eds1 (v2/e1), and var2-9 pad4 (v2/p4) seedlings grown under CL (40 μmol m−2 s−1 at 22°C ± 2°C) were collected to analyze the transcript levels of SRGs using RT-qPCR. Values are means ± sd of three independent biological samples. PP2A was used as an internal control. Lowercase letters indicate statistically significant differences between mean values (P < 0.05, one-way ANOVA with posthoc Tukey’s HSD test).
