Function
function
Catalyzes xyloglucan endohydrolysis (XEH) and/or endotransglycosylation (XET). Cleaves and religates xyloglucan polymers, an essential constituent of the primary cell wall, and thereby participates in cell wall construction of growing tissues.
Miscellaneous
Knockdown mutants have shorter roots, decreased cell wall xyloglucan content and increased aluminum resistance.
