Phenotype and drought tolerance of wild type (WT) and transgenic lines (#4 and #19). (A-B) Representative photographs of potted plants of WT, #4 and #19 that have been exposed to water stress for 7 d (A) and 21 d (B). (C-D) Electrolyte leakage (C) and total chlorophyll content (D) of WT, #4 and #19 after 7 d of water stress. * and ** indicate that values of the two transgenic lines were significantly different from those of WT at P < 0.05 and P < 0.01, respectively.
