Fig 7. The relative expression levels of biotic and abiotic stress-related genes of WT and SlDEAD31-overexpressing plants under normal and salt stress conditions.

8-week-old plants were irrigated with water containing 400 mm NaCl (200 mL) from the bottoms of the pots, then root samples were harvested after 24 and 48 h. Seedlings harvested before the salt stress were used as controls. Bars represent mean relative expression values ± SE (n = 3). Asterisks indicate a significant difference (P<0.05) between WT and transgenic plants.
