土地盐渍化是一个全球性的资源与生态问题,严重制约当地经济和社会的发展。随着分子生物学的迅速发展,基因工程为林木耐盐碱新品种培育提供了一条新的途径,一批林木耐盐碱相关基因相继被克隆、功能得到定位,并通过遗传转化获得了一些林木耐盐碱转基因株系。文中综述了近10年与林木耐盐碱相关的渗透调节保护基因、功能蛋白基因、调节蛋白基因、抗氧化酶基因等的克隆及其工程应用2方面的研究进展,并对该领域的未来研究重点进行了探讨,以期为相关研究提供参考。
Land salinization is a global resource and ecological problem that severely restricts the development of local economy and society. With the rapid development of molecular biology, genetic engineering has provided a new way to cultivate new salt-tolerant forest trees. A number of salt-alkali-related genes of forest trees have been cloned and their functions have been located. Some trees have been obtained through genetic transformation Salt-tolerant transgenic lines. In this paper, the progress of the cloning of osmotic regulatory genes, functional protein genes, regulatory protein genes and antioxidant enzyme genes related to salinity and alkalinity of forest trees and their engineering applications in recent 10 years are reviewed. The future research in this field Focusing on the discussion, with a view to provide a reference for the relevant research.
