【摘要】 肉桂醇脱氢酶(cinnamyl alcohol dehydrogenase,CAD)作为植物次生代谢特别是木质素合成的关键酶,与植物生长发育和抵御病原菌入侵关系密切,研究CAD基因表达调控及其与组织木质化的关系具有重要的植物生理学意义.该文综述了植物CAD的蛋白特征、酶学性质、基因分布和分类、基因结构和表达调控以及CAD表达与木质素合成的关系,为研究CAD在植物生长发育和抗病中的作用提供理论指导.更多还原

【Abstract】 As a critical enzyme in secondary metabolism of plants,especially in the important reaction of the biosynthesis of lignin,cinnamyl alcohol dehydrogenase(CAD) has the close relationship with plant development and resistance pathogen invasion.It has the significant biological meaning to research the CAD gene expression and regulation and related lignification.The molecular structure,enzymatic characters,gene distribution and classification,gene structure and expression regulation of CAD,and the relationships lignification in plants were reviewed,in order to provide a theoretical guidance for the study of CAD in plant development and disease resistant.更多还原
