转基因耐盐水稻研究进展

Research Progress on the Development of Transgenic Rice for Salt Tolerance

摘要: 胁迫是水稻生长发育的主要逆境之一，影响水稻产量和品质，因而提高水稻的耐盐能力是水稻育种工作急需解决的关键问题。本文对水稻耐盐分子机理、耐盐相关新基因的定位和克隆，以及耐盐转基因水稻培育等几方面的研究进行了综述，并对该领域的前景进行了展望和讨论，以期为水稻抗盐转基因改良提供参考。

Abstract: Salinity is one of the main factors which affect the growth and development of rice. Therefore, improving the capacity of rice salt-tolerance is urgently needed for its breeding. In this review, the mechanism of salt-tolerance in rice, cloning of salt-tolerance related genes and transformation of these genes into rice were reviewed. The prosperity of transgenic rice with salt resistance was predicted and potential problems existing in this field were discussed, as to support totally comprehension and advice for researchers in this field. It will provide some valuable information for the efficient development of transgenic rice tolerant to salt.
