摘　　要：Na+/H+Antiporter基因与植物耐盐性密切相关,其编码产物Na+/H+逆向转运蛋白通过Na+外排和Na+区隔化来维持植物细胞内较低的Na+水平,降低Na+的毒害,从而对植物的耐盐性起重要作用。<Abstrcat>There is close correlation between Na^+/H^+ Antiporter gene and the salt tolerance of plants. Na^+/H^+ Antiporter protein maintains lower Na^+ level through extruding Na^+ from the cells and compartmentalizing Na^+ into the vacuole, and decreases Na^+ detrimental effect, and thus plays an important role in the salt tolerance of plants.

关 键 词：渗透胁迫 调节基因 Na^+/H^+ Antiporter基因 植物耐盐性
