【摘要】 本文从作物耐离子胁迫、耐渗透胁迫和细胞编程性死亡调节三个方面概述了作物耐盐的生理生化机制 ;介绍了目前利用分子生物学技术克隆与植物耐盐相关的基因 ,并根据作物的耐盐机理 ,对这些与耐盐相关的基因进行了分类 ;总结分析了转耐盐基因植物的研究现状及其转基因植物的耐盐性状况 ,并提出了利用转基因技术 ,改良植物耐盐性的方法和对策。更多还原

【Abstract】 The physiological and biochemical mechanisms of crop salt tolerance are reviewed from three aspects including resistance to iron stress,osmotic stress and programmed cell death.The main cloned halotolerance genes today by molecular biology technology are discussed.And these genes are sorted according to the mechanism of crop salt tolerance.The conditions of research and salt tolerance about trans-halotolerance gene plants are concluded and analogied.The method to improve crop salt tolerance by transgenetic technology is proposed.更多还原
