摘　　要：在各种环境胁迫中,盐胁迫是造成作物减产的严重环境因素之一。主要从耐盐的生理机制和一些下游调节过程入手,包括:离子区隔化、渗透调节、激素调节、去毒化作用、光合途径的改变等,讨论了植物耐盐工程的新进展;同时还讨论了分子水平育种的影响因子。Soil salinity,one of the major abiotic stresses reducing agricultural productivity,affects large terrestrial areas of the world. In this paper we will discuss the mechanisms of salt tolerance in some detail,focusing on the recent experimentation with transgenic plants that has led to increased salinity tolerance,with emphasis on the areas of ionic compartmentation, osmoregulation,antioxidants,plant hormones and converted photosynthesis pathway. Meanwhile prospects for the salt tolerant molecular breeding are provided.
