PP2AB′1 regulates ABA responses in leaves and seeds. A, The number of lateral roots formed in pp2aB′1-1 is similar to that in the wild type (WT) in response to ABA treatment. Values are means ± sd from three biological replicates (n = 30). B, The germination of pp2aB′1 mutant seeds is hypersensitive to ABA. Values are means ± sd from three biological replicates. Asterisks indicate significant differences in comparison with the wild type (Student’s t test; P ≤ 0.01; n = 300). C, The fresh weight of detached leaves was used to measure relative water loss over time. pp2aB′1-1 shows slower water loss than the wild type. Values are means ± sd from three biological replicates.
