本文综述了细胞壁木质化和木质素局部化学的超微结构方面。木质化是由位于细胞角落和中层的未知因素（起始位点）引发的单木质素的酶介导聚合反应引起的。木质化导致碳水化合物基质内的孔按照从壁的外部区域朝向管腔的顺序填充。木质素的数量和化学特性在细胞壁上随着反应木的存在而变化。和细胞类型之间的关系。(C)2001爱思唯尔科技有限公司版权所有。
This review discuses the ultrastructural aspects of cell wall lignification and lignin topochemistry. Lignification results from the enzyme mediated polymerization of monolignols initiated by unknown factors (initiation sites) located at the corners of cells and in the middle lamella. Lignification results in the filling of pores within the carbohydrate matrix following a sequence from the outer regions of the wall towards the lumen. The amount and chemical characteristics of lignin vary across the cell wall, with the presence of reaction wood. and among cell types. (C) 2001 Elsevier Science Ltd. All rights reserved.
