脱水诱导基因RD特性及功能

Research of dehydration-inducible gene RD in characterization and function

脱水诱导基因(Responsive to Dehydration,RD)是一类能够调节植物脱水的基因,对植物脱水胁迫具有一定耐受性,有些成员还对低温、高盐等非生物胁迫具有不同程度的响应。RD成员分属于不同家族,在结构和功能方面存在差异。归纳不同RD的结构组成、蛋白保守基序、调控机理以及应对生物以及非生物胁迫时的功能,以及RD基因启动子区域中不同的顺式作用元件在基因应对非生物胁迫时发挥的作用,可为今后对RD基因的研究提供相关参考。

Responsive to dehydration(RD)is a class of genes that regulates dehydration in plants.They are functionally tolerant to plant dehydration,some of which are responsive to abiotic stresses such as low temperature and high salinity.However,they belong to different families,respectively,and have discrepancy in the structure and function.In this paper,the structural composition,conserved motif,regulatory mechanism,and the function in response to biotic and abiotic stress were summarized in different RDs,as well as the different cis-acting elements in the promoter region played a role in response to abiotic stress so as to provide relevant basis for future researches on RD.
