摘要:

半纤维素多糖木葡聚糖(XyG)存在于大多数植物的初生细胞壁中, 对细胞壁的结构组织和生长发育具有重要的调控作用。XyG在植物进化中存在结构的多样性。该文概述了参与XyG合成的糖基转移酶的最新研究进展, XyG合成需要多种糖基转移酶参与, 这些酶类很可能以蛋白酶复合体的形式存在并发挥作用, XyG的结构和组成的改变对植物的生长发育也产生影响。

Abstract:

The hemicellulosic polysaccharide xyloglucan (XyG), found in the primary cell walls of most plants, plays important roles in structural organization of plant cell walls and regulation of growth and development. Recent research in structural characterization of XyGs from different plant species revealed the diversification of XyG during plant evolution. This paper reviews progress in studies of glycosyltransferase genes involved in XyG biosynthesis. Most of the XyG-specific glycosyltransferases have been identified, and some of them appear to form a complex for involvement in XyG biosynthesis. We discuss how changes in XyG structure affect plant growth and development.
