Drought stress treatment on the growth of the transgenic CrPIP1;5 overexpression lines (OX 1#, OX 5#, and OX 10#) and wild-type (WT) plants under natural growth conditions in vermiculite. a Leaf phenotypes of the transgenic line and WT plants under drought treatment. b The survival rates of the OX lines and WT plants. Bars show mean values ± SD of n = 3–4 biological replicates. The significance level was defined as * (P < 0.05) and ** (P < 0.01)
