摘　要：

植物细胞壁是植物细胞的特征性结构。植物体中, 所有细胞都会形成初生壁的结构, 而一些特定组织的细胞会在初生细胞壁内侧进一步加厚形成次生壁, 为这些细胞实现正常生理功能和高等植物发育提供必需的结构。本文分别从转录水平调控、激素调控、加厚模式调控及人工调控等方面介绍目前对于次生细胞壁加厚调控的研究进展。

Abstract:

The plant cell wall is unique characteristic of plant cells. In plants, all cells have primary cell wall while some cells in certain tissues form thickened secondary cell walls which are essential for higher plant development. This review summarizes recent studies of the regulation of secondary cell wall thickening including transcriptional regulation, hormonal regulation, regulation of wall-thicken patterns and engineering of secondary cell walls.

Key words: secondary cell wall; transcriptional regulation; lignin; cellulose
