中文摘要：

运用松树根特异性启动子PmPgPR10驱动把CMO／BADH双价基因转入水稻，对转基因植株根和叶的CMO酶、BADH酶活性及其它生理生化指标进行了测定，结果表明：CMO／BADH双价基因能在根部特异性表达．文章还对转基因提高植株耐盐性的机理进行了探讨。

英文摘要：

Root-specific expression of CMO/BADH driven by root-specific promoter PmPgPR10 was confirmed by detecting the enzyme activities of CMO and BADH in transgenic rice, which proved the root-specific promoter worked expectedly in transgenic rice. Other physiological and biochemical indexes and the salt-tolerance mechanism in transgenic plant were discussed as well.
