Expression of rd29A::AtDREB1A/CBF3 in tomato alleviates drought-induced oxidative stress by regulating key enzymatic and non-enzymatic antioxidants

Transgenic tomato lines (cv. Kashi Vishesh) over-expressing AtDREB1A/CBF3 driven by stress-inducible rd29A promoter showed significantly higher activities of key antioxidant enzymes when exposed to water-deficit for 7, 14, and 21 days. Transgenic tomato plants exposed to water-deficit recorded lower levels of hydrogen peroxide and superoxide anion formation compared to the non-transgenic plants, suggesting alleviation of reactive oxygen species...
