Involvement of cytosolic ascorbate peroxidase and Cu/Zn-superoxide dismutase for improved tolerance against drought stress.
In order to understand the role of cytosolic antioxidant enzymes in drought stress protection, transgenic tobacco (Nicotiana tabacum cv. Xanthi) plants overexpressing cytosolic Cu/Zn-superoxide dismutase (cytsod) (EC 1.15.1.1) or ascorbate peroxidase (cytapx) (EC 1.11.1.1) alone, or in combination, were produced and tested for tolerance against mild water stress. The results showed that the sim...
متن کاملStudies on Salt Tolerance of Transgenic Sweetpotato which harbors two Genes Expressing CuZn Superoxide Dismutase and Ascorbate Peroxidase with the Stress-inducible SWPA2 Promoter
In this study, some physiological indexes of leaves in transgenic sweetpotato (Ipomoea batatas L. cv. Yulmi), which harbors two genes CuZn superoxide dismutase (CuZnSOD) and ascorbate peroxidase (APX) genes, with the stress-inducible SWPA2 promoter were evaluated under different concentrations of NaCl treatment. The results showed that physiological indexes were no remarkable differences withou...
متن کاملOverexpression of Superoxide Dismutase Protects Plants from Oxidative Stress' lnduction of Ascorbate Peroxidase in Superoxide Dismutase-Overexpressing Plants
Photosynthesis of leaf discs from transgenic tobacco plants (Nicotiana tabacum) that express a chimeric gene that encodes chloroplast-localized Cu/Zn superoxide dismutase (SOD+) was protected from oxidative stress caused by exposure to high light intensity and low temperature. Under the same conditions, leaf discs of plants that did not express the pea SOD isoform (SOD-) had substantially lower...

متن کاملA Novel Thylakoid Ascorbate Peroxidase from Jatrophacurcas Enhances Salt Tolerance in Transgenic Tobacco
Ascorbate peroxidase (APX) plays an important role in the metabolism of hydrogen peroxide in higher plants. In the present study, a novel APX gene (JctAPX) was cloned from Jatropha curcas L. The deduced amino acid sequence was similar to that of APX of some other plant species. JctAPX has a chloroplast transit peptide and was localized to the chloroplasts by analysis with a JctAPX-green fluores...
