摘　　要：甲酸脱氢酶(Formate dehydrogenase,FDH)广泛存在于各类生物体内,归属D-2-羟基酸脱氢酶超家族,主要依赖烟酰胺腺嘌呤二核苷酸(Nicotinamide adenine dinucleotide,NAD+)或氧化型烟酰胺腺嘌呤二核苷酸磷酸(Nicotinamide adenine dinucleotide phosphate,NADP+)作为辅因子,催化甲酸氧化生成CO_(2)和水.FDH在不同研究中被发现具有多种重要的生物学功能,如在植物中FDH参与一碳化合物代谢过程,并且在响应环境胁迫(包括低氧或缺氧等)条件下发挥重要作用.对FDH及其编码基因的功能和在植物逆境胁迫响应中的作用等方面的研究结果进行总结概述,为深入研究植物FDH提供理论基础.Formate dehydrogenase(FDH)widely spreads in different organisms,belongs to the D-2-hydroxy acid dehydrogenase superfamily,catalyzes the oxidation of formic acid to produce CO_(2) and water,when mainly relying on nicotinamide adenine dinucleotide(NAD+)or nicotinamide adenine dinucleotide phosphate(NADP+)as cofactors.FDH has been found to have several important biological functions in different studies,for example,in plants,FDH is involved in one-carbon compound metabolism and plays an important role in response to environmental stresses,including hypoxia or anoxia,and other conditions.The research results on the functions of FDHs and their encoding genes,and their roles in plant stress responses were summarized,to provide a theoretical basis for the in-depth study of plant FDH.
