植物甲酸脱氢酶基因的表达调控及其生理功能研究进展

甲酸脱氢酶（FDH）是植物中普遍存在的一种含量丰富的酶。甲酸脱氢酶也是一种NAD依赖的酶，它催化甲酸氧化成二氧化碳的可逆反应。植物FDH是植物一碳代谢的一部分，它在植物响应各种环境胁迫、低氧或缺氧过程中发挥着重要的作用，因此在农学生产上具有很大的应用潜力。最近植物来源的FDH基因克隆和表达调控及其生理学功能等各方面的研究都取得很多重要的进展。综述了近年来植物来源的FDH基因克隆和表达调控及其生理学功能方面的研究进展。

Research Progresses on Gene Regulation and Physiological Role of Plant Formate Dehydrogenase

Formate dehydrogenase (FDH) is an abundant enzyme which is present widely in plants. FDH is also an NAD+-dependent enzyme which catalyzes the reversible oxidation of formate to carbon dioxide. As a component of one-carbon metabolism in plants, the enzyme played an important role in response to various environmental stresses and low oxygen or hypoxia in plants，and has great potential for application in agricultural production. Recently, considerable progresses have been made for plant FDH in gene cloning, gene regulation and physiological functions. The recent progresses on gene cloning, gene expression regulation, physiological roles of plant FDH were reviewed.
