水稻耐盐转基因研究进展

Advances in Transformation of Salt Tolerance Gene in Rice

土壤盐渍化正吞噬着人类赖以生存的有限的土地资源,已经成为严重制约农业生产的另一个全球性问题。提高作物的耐盐能力是植物育种工作急需解决的关键问题。随着现代分子生物技术的飞速发展,人们寄希望于基因工程培育耐盐品种。科研工作者已经鉴定和克隆出一批耐盐碱相关的基因,这些基因的利用已成为培育耐盐水稻品种的主要途径之一。通过耐盐相关基因转化,已经获得了一些耐盐性提高的转基因水稻。本文就植物耐盐机理、耐盐相关基因的克隆及转耐盐基因水稻等几个方面进行了综述,并对该领域的前景进行了展望。

Soil salinization swallowing the limited farm land of mankind＇s has become another global serious constraint for agricultural production.Improving the capacity of crop salt-tolerance is urgently needed for plant breeding.With development of modern molecular biology technology,genetic engineering was expected for breeding the salt-tolerant plant.Scientific workers have cloned a number of salt-tolerance related genes which have been used for rice breeding.Salt-tolerance of the transgenic rice has been improved to some extent.In this paper,the mechanism of salt-tolerance in plant,salt-tolerance related gene cloning and transformation of the genes into rice were reviewed.The prospect of the research area was also illustrated.
