摘　　要：苹果酸脱氢酶(malate dehydrogenase,MDH)广泛存在于生物体中,具有高度的保守性,在各种生物代谢途径中起着重要作用。苹果酸脱氢酶是三羧酸循环过程中的关键酶,在植物中,苹果酸脱氢酶还参与CO_(2)同化中的丙酮酸羧化途径、细胞质内的氧化还原调节等过程,并参与种子萌发、植物抗逆相应等过程,长期以来都是人们研究的热点。本研究对苹果酸脱氢酶在植物中的研究进展进行概括总结,主要包括苹果酸脱氢酶基因的结构分类、生化功能机制、参与的植物生理过程以及在植物抵抗逆境过程中的作用等方面,本研究对植物苹果酸脱氢酶的进一步深入研究提供理论依据。Malate dehydrogenase(MDH)is a kind of enzyme widely presented in organisms,which is highly conserved and plays important roles in various biological metabolic pathways.MDH is a key enzyme in tricarboxylic acid cycle,also participates in pyruvate carboxylation pathway of CO_(2) assimilation,cytoplastic redox regulation,seed germination,plant stress resistance resp onses,and other processes in plants,which has been a research hotspot for a long time.This study summarizes the research progresses of plant malate dehydrogenases,mainly including the structural classification,biochemical function mechanisms,functions in plant physiological processes,and roles in plant stresses responses,this study provide theoretical basis for the further researches of plant malate dehydrogenases.
