摘要
土壤盐碱化是目前全球最严重的环境问题之一,包括人口膨胀在内的各方面因素使人类不断开发和利用大面积的土地,逐渐生成新的次生盐渍化,加速了土壤盐碱化的进程。通过农业生物技术培育耐盐植物品种或开发利用有经济价值的盐生植物资源以改良土壤已成为研究热点。文中综述了植物耐(抗)盐碱逆境胁迫的相关基因和外源基因遗传转化的方法,并对现今生物耐(抗)盐碱逆境胁迫的基因转化研究进行了展望。
The soil salinafion is a significant abiotic stress for agricultural production and ecolcgical environment. The study on tolerance to salt soil by transforming genes from other organisms into some kinds of plants to reform and apply salt soft has become a significantly hot point. In this paper, some generally-used genetic transfonnlng methods and some principal genes related to tolerance to salt were summarized. And projects were put forward on base of current studies on the transforming genes.
