Overexpression of ThST5 significantly improves salt tolerance in cotton. A Seed germination of wild type control (CK) and ST5 overexpression line (ST5-OE) under water or 250 mmol·L⁻¹ NaCl for two weeks. Photographs were taken at the 8th day after sowing. Bar = 4 cm. B Germination rate of transgenic seeds and CK in water or 250 mmol·L⁻¹ salt treatment. Values are mean ± SD (standard deviation) of three biological replicates. Different letters represent significant difference (P < 0.05) as calculated by Duncan’s multiple range tests
