Pro-35S:AtPAP15 overexpressor and T-DNA knockout mutants have altered salt, osmotic stress, and ABA sensitivities. Seeds were germinated and grown on MS plates as controls, MS plates with 150 mm sorbitol, MS plates with 150 mm NaCl, and MS plates with 1 μm ABA. Compared to the wild type, Pro-35S:AtPAP15 had increased tolerance to salt stress and osmotic stress and decreased ABA sensitivity, whereas the T-DNA knockout mutant S004877 was less tolerant to these conditions. Bars represent mean (n = 4).
