Effect of PP2C-37b, PP2C-77a, ABI5-5b, SAPK3, and HPt3a overexpression on the abiotic stress resistance of apple calli. (a) Apple calli transfected with an empty vector (1), PP2C-37b-overexpression calli (2), PP2C-77a-overexpression calli (3), ABI5-5b-overexpression calli (4), SAPK3-overexpression calli (5), and HPt3a-overexpression calli (6) were grown under 16 °C with 40% PEG8000 and 100 mM NaCl simultaneously. (b) Measurement of calli weight. Transfected apple calli were weighed before treatment (0 d) and after 12 d of treatment. (c) Relative intensity of NBT staining for transfected apple calli after treatment. (d) Relative intensity of DAB staining for transfected apple calli after treatment. Samples with different letters are significantly different P < 0.05.
