Cleaves and religates xyloglucan polymers, an essential constituent of the primary cell wall, and thereby participates in cell wall construction of growing tissues (By similarity).CATALYTIC ACTIVITY:Breaks a beta-(1->4) bond in the backbone of a xyloglucan and transfers the xyloglucanyl segment on to O-4 of the non-reducing terminal glucose residue of an acceptor, which can be a xyloglucan or an oligosaccharide of xyloglucan.TISSUE SPECIFICITY:Root specific.INDUCTION:By brassinolide. Strongly down-regulated by abscisic acid.PTM:Contains at least one intrachain disulfide bond essential for its enzymatic activity (By similarity).SIMILARITY:Belongs to the glycosyl hydrolase 16 family. XTH group 1 subfamily.WEB RESOURCE:Name=XTH-World; URL=""http://labs.plantbio.cornell.edu/XTH/""; "
