General Information

General Information Comment Organism
physiological function the primary cell wall of flowering plants consists of cellulose fibrils tethered by hemicelluloses (principally xyloglucans) and embedded in an amorphous matrix of pectins and glycoproteins. Plant cell expansion is mainly regulated by cell wall extensibility and results from selective loosening and rearrangement of the load-bearing cellulose/xyloglucan network, at least in flowering plants with type I cell walls where xyloglucan is a predominant hemicellulose. Xyloglucan endotransglucosylase/hydrolases (XTHs), a class of cell wall-modifying proteins, also have the capacity to loosen cell walls. Most XTHs cut and rejoin xyloglucan by xyloglucan endotransglucosylase, EC 2.4.1.207, action, whereas some XTHs hydrolyse xyloglucan by xyloglucan hydrolase, XEH EC 3.2.1.151, action Populus tremula x Populus tremuloides
