Changes in the concentrations of Na+ and K+ and salinity-related gene expression in apple leaves under salinity stress. a. The concentration of Na+. b. The concentration of K+. c. Ratio of Na+ to K+. dn. The relative expression of MdSOS1, MdSOS2, MdSOS3, MdNHX1, MdNHX2, MdNHX4, MdNHX6, MdAKT1, MdAKT2/3, MdKAT1, and MdKEA2 in apple leaves. Three-month-old seedlings of transgenic and WT plants were irrigated with 200 mM NaCl for 12 days, and the leaves were used for physiological analyses. Different letters indicate significant differences between treatments, according to and Tukey’s multiple range tests (P<0.05)
