SmAKT1 is involved in response to salt stress in yeast and Arabidopsis under salt condition. a Expression of SmAKT1 and AKT1in yeast mutant strain R5421. Yeast cells were plated on AP medium containing various concentrations of Na⁺ (100, 200 and 300 mM) with different K⁺ concentrations (1, 5 and 10 mM). b Phenotype comparison of the four Arabidopsis lines after 200 mM NaCl treatment for 0 and 7 days. c Real-time quantitative PCR analysis of the expression pattern of SOS1, HKT1 and NHX in the four Arabidopsis lines treated without (control) or with 200 mM NaCl for 12 h and 7 days. Bars represent means ± SD of three biological replicates. Columns with different letters indicate significant differences at P < 0.05 (Duncan’s test)
