Plant wall polysaccharide, which is mainly composed of cellulose, hemicellulose and pectin, determines the shape of the cells. During cell enlargement, wall loosening occurs by cleavage of xyloglucan tethers of cross-linkage between cellulose microfibrils and, hydrogen-bonds,in which endo-1,4-b-glucanase, xyloglucan endotransglycosylase/hydrolase and expansin could be involved. To realize the mechanism of wall loosening induced by these apoplastic proteins, we analyzed property of the proteins heterologously expressed in Nicotiana Benthamiana using a virus vector. I present the expression, characteristic and localization of the proteins.
