摘　　要：次生壁是植物细胞停止伸长和生长之后在初生细胞壁内侧继续积累形成的细胞壁,其主要成分是纤维素、半纤维素以及木质素。次生壁是植物光合作用产物储存的主要形式之一,为人类社会提供大量的纤维和生物能源。植物次生壁的合成是一个复杂的生物学过程,包括次生壁各相关组分的生物合成、定向分泌以及装配等。本研究从次生壁的三大组分(纤维素,半纤维素,木质素)的合成及相关酶调控的角度,阐述了植物次生壁的生物合成途径,展望了其研究前景及亟需解决的问题,对“定制次生壁”培育出满足不同人类需要的植物具有重要的指导意义。The plant secondary cell wall,which is synthesized after the cell elongation and expansion inside of the primary cell wall,is mainly composed of cellulose,hemicellulose and lignin.Second cell wall comprises the mainly component of the photosynthetic products,providing a large amount of fiber and bioenergy for human.The production of secondary cell wall contains many complex biological processes,including the biosynthesis,targeted secretion,and assembly of related components of the secondary cell wall.This review aims at clarifying the synthesis of cellulose,hemicellulose,lignin and regulation of related enzymes.And this review summarizes research prospects and the problems that need to be solved urgently,meanwhile it has important guiding significance for"customized secondary wall"to cultivate plants that meet different human needs.
