Stomatal movement phenotype of WT, ipmdh1/ipmdh1 and ipmdh1/ipmdh1 ipmdh2/IPMDH2 ipmdh3/ipmdh3 mutants in response to 50 μM ABA. (a) Hyposensitivity of stomatal closure in ipmdh mutants. (b) Hyposensitivity of stomatal opening in ipmdh mutants. Mutant1 and mutant2 represent ipmdh1/ipmdh1 and ipmdh1/ipmdh1 ipmdh2/IPMDH2 ipmdh3/ipmdh3 genotypes, respectively. Each experiment was repeated four times with 105 ± 5 stomata measured for each sample. Each data point represents average stomatal aperture ± standard error. Asterisks indicate that the data point was significantly different between genotypes under the same treatment at the same time point (Student’s t test, p < 0.01).
