Salt stress tolerance of SlbZIP1-RNAi plants. Representative phenotypes of WT and transgenic tomato plants at 0 d (a), 8 d (b) and 16 d (c) after salt stress. 8-week-old plants were irrigated with 200 mL 400 mM NaCl every 72 h from the bottom of the pots. Representative plants are shown. d Survival rate of the plants shown after 16 d of salt stress and 5 d of recovery. Bars represent the mean of three biological replicates of 20 plants each. e-i Comparisons of ABA content (e), chlorophyll content (f), MDA content (g), CAT activity (h), and Pro content (i) between WT and transgenic plants at 0, 8 and 16 d after salt stress. Bars represent the mean of three biological replicates ± SE. Asterisks indicate statistical significance (*0.01 < P < 0.05, **P < 0.01) between WT and transgenic plants, respectively
