Free radical-scavenging ability and level of soluble proline in the wild type (WT) and JA biosynthesis mutants. (A) DPPH free radical-scavenging activity of standard butylated hydroxyanisole (BHA) and methanolic extract of WT and JA biosynthesis mutants under salinity stress of 100mM NaCl for 3 d. (B) IC50 values were calculated from (A) depending on regression analysis. (C) Soluble proline in the WT, cpm2, and hebiba under salt stress. Proline was not detectable in control samples of the same genotypes. Values represent the mean of at least three independent experiments ±SE. Results for the WT, cpm2, and hebiba are indicated by white, grey, and striped bars, respectively. The dotted symbols in (A) and (B) represent the measurement for BHA. Significant differences amongst different treatments or genotypes are indicated by different letters, according to Tukey’s Honestly Significant Difference (HSD) test (P<0.05).
