关 键 词：Glutathione reductase oxidative stress transformed tobacco 

摘      要：To investigate the possible mechanisms of glutathione reductase(GR) in protecting against oxidative stress,we obtained transgenic tobacco(Nicotiana tabacum) plants with 30-70%decreased GR activity by using a gene encoding tobacco chloroplastic GR for the RNAi *** investigated the responses of wild type and transgenic plants to
