Fig. 5From: Abscisic acid mediated proline biosynthesis and antioxidant ability in roots of two different rice genotypes under hypoxic stressEffects of exogenous ABA and ABA inhibitor on the relative expression of genes related to proline metabolism in the Nip cultivar. P5CS1 (a), P5CS2 (b), OAT (c), and ProDH (d). DW represents dry weight. Data are the mean ± SE of three independent experiments. Different letters indicate significant differences at P < 0.05 using the least significant difference (LSD) testBack to article page
