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.

Key words: xyloglucan (XyG), glycosyltransferase, cell wall, biosynthesis
