摘要
系统地讨论了甜菜碱在提高植物抗盐性中的作用机理及其国内外研究进展,并对甜菜碱生物合成过程中关键酶及其遗传工程的研究进展进行了综述.提出在进一步弄清甜菜碱提高植物抗盐性作用机理的基础上,应在重要作物中开展甜菜碱合成相关基因的导入,以期获得耐盐植物新品种.
The paper systematically discusses the mechanism for glycinebetaine to improve plant salt resistance and its research advances in genetic engineering at home and abroad as well as summarizing the research progresses about the key enzymes and their genetic engineering in glycinebetaine biosynthesis. It suggests that on the basis of further understanding the mechanism for glycinebetaine to improve plant salt resistance,the transformation of the genes relating to glycinebetaine biosynthesis should be carried out in major crops so that new plant varieties resistant to salt can be obtained.
