Table I. Regulation of drought/high-light stress tolerance and YS by LSD1, EDS1, and PAD4.
After stress, all plants were rewatered and cultivated in ambient laboratory conditions for an additional 3 weeks until the seeds were harvested. The results are representative of two independent experiments (n = 10–15 ± se). Asterisks indicate a significant difference compared with Ws-0 at the level *P < 0.05 by Tukey’s multiple comparison test.
