Statistical analysis of plant height and chlorophyll and carotenoid contents in transgenic and WT Arabidopsis. The transgenic and wild-type Arabidopsis grown in MS agar plates for 14 days: 200 mM Nacl and 500 mM mannitol were added to MS medium in drought treatment and salt treatment groups, respectively. (A,B) Length of rosette leaf (A) and maximum length of root system (B) in transgenic lines and wild-type. Different letters above the columns indicate significant differences (p ≤ 0.05, n = 20). (C,D) Chlorophyll (C) and carotenoid (D) contents in transgenic lines and wild-type Arabidopsis. Different letters above the columns indicate significant differences (p ≤ 0.05, n = 3).
