SlHyPRP1-RNAi (Ri) transgenic plants have improved oxidative stress tolerance. (A) Accumulation of H₂O₂ in the WT and transgenic lines (Ri-3) under dehydration measured by histochemical staining with DAB. The leaves of WT and Ri-3 before detached (upper panel) and after detached for 3 h (lower panel). (B) Water loss rate of the transgenic and WT plants expressed as a percentage of the initial fresh weight (n = 15). (C) Comparison of the growth of T₂ transgenic tomato plants post-treatment of oxidative stress to the non-stress control. (D) The transcript levels of super oxygen dehydrogenases (SOD), catalase (CAT), and methionine sulfoxide reductase (MSR B) were quantitatively analyzed in WT and SlHyPRP1-RNAi transgenic lines. Error bars indicate ± SE of means (n = 3).
