title: Paraquat tolerance of transgenic Nicotiana tabacum with enhanced activities of glutathione reductase and superoxide dismutase.
abstract: Transgenic tobacco with enhanced cytosolic activities of glutathione reductase and superoxide dismutase were generated by cross-fertilization. Leaves of the hybrids exhibited further increased tolerance to a O2-.-generating herbicide paraquat than those of their parents. This result indicates the efficiency of manipulating more than one gene in improving resistance of plants to photooxidative stress.
