Response of GAPC and PLDδ Mutants to ABA and Water Deficits.
(A) Changes in stomatal aperture after ABA (25 μM) or H2O2 (100 μM) treatment. Values are means ± se (n = 50). Different letters mark significant differences from each other (ANOVA, P < 0.05). WT, the wild type.
(B) Stomatal conductance, cumulative water transpiration, photosynthesis, and dry weight. Asterisks mark significant difference from the wild type under the same growth condition. Values are means ± se (n = 16).
