| Abstract: | 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. |
