Figure 6.

Constitutive expression of NPX1 and potassium deprivation increased the biosynthesis of ABA. A, ABA concentrations in leaves of wild-type (WT), NPX1-ox, and npx1-1 plants grown on agar plates. Data represent means of three biological replicates each containing multiple plants. B, Comparison of ABA concentrations in leaves or roots of plants grown under full nutrient conditions (+NPK) or K+ deficiency (−K) for 6 or 30 h. Data represent means of six biological replicates. Asterisks indicate significant differences as compared with other means in each subfigure (* P < 0.05, ** P < 0.01, by Student's t test).
