GT47A — Asparagus officinalis

Summary

A4U43_C09F15820 (symbol GT47A, preferred name AoIRX10) on asparagus chromosome 9 encodes a glycosyltransferase family 47 IRX10 protein with an exostosin domain, possessing glucuronoxylan glucuronosyltransferase and transglycosidase activities. The gene is associated with glucuronoxylan and xylan anabolism, glycoprotein anabolism, secondary cell wall biogenesis, and cell wall organization, and its product localizes to the Golgi membrane. It has been linked to xylan biosynthesis. Studies of related genes in other species connect the family to xylan synthesis, though this is not established for the asparagus gene itself.
