摘要
从盐生植物里分离相关抗盐碱功能基因,是研究植物抗盐碱机理和选育耐盐碱植物新品种的关键。碱茅不仅是一种优良的牧草,还是一种宝贵的盐生种质资源,为相关研究提供了丰富的耐盐碱基因。从碱茅中分离克隆这些基因,并分析其结构、功能及表达特性,不仅有助于培育耐盐碱转基因作物,而且可以为我国盐碱草地的改良和治理提供理论依据。因此,笔者综述了近年来碱茅耐盐碱基因的研究进展。
Cloning functional salt-alkali tolerance genes of halophytes plant is the key for understanding the molecular mechanism of plant salt-alkali tolerance,and breeding new salt-alkali tolerant plants.Alkaligrass(Puccinellia),as a excellent pasture and valuable halophytes germplasm,provides us with a wealth of salt-alkali tolerance genes.By cloning the salt-alkali stress-induced genes of Alkaligrass,and analyzing their structure,function and expression,we not only possibly breed new salt-alkali tolerance GM plants,but also provie theory support for the improvement of saline soil.So,the present paper summarizes the advancement in the research on salt-alkali tolerance genes.
