甜菜碱与植物抗旱/盐性研究进展

Research progress on relationships betaine and drought/salt resistance of plants

系统地讨论了甜菜碱在植物体内的代谢特性与甜菜碱合成酶基因工程、甜菜碱生理功能与植物抗旱/盐生理的关系以及外源甜菜碱调控植物抗旱/盐性研究进展,最终实现通过施用外源甜菜碱和利用基因工程技术将合成甜菜碱的代谢途径引入植物,以抵抗由于干旱/盐胁迫对植物造成的伤害,为其农业利用开辟新途径。

Research progress was discuss systemically on metabolism characteristics of inner betaine in plant and gene engineering of synthetical enzyme,relations between physiological function of inner betaine and drought resistance/salt resistance and physiological mechanism of exogenous betaine in increasing drought resistance/salt resistance of plants.By applying exogenous betaine and introducing metabolism approach to plants by gene engineering technique,the damage was counteracted because of adversity menace to open a new path to use it in agriculture.
