XT1 — Asparagus officinalis

Summary

A4U43_C01F33070, designated XT1 or AoXT1 in asparagus (Asparagus officinalis) on chromosome 1, encodes a glycosyltransferase 61 catalytic domain-containing protein with glycoprotein 2-β-D-xylosyltransferase, xylosyltransferase, alpha-mannosidase, UDP-xylosyltransferase, and protein binding activities. The gene is associated with protein N-linked glycosylation, posttranslational protein membrane targeting and translocation, xylan anabolism, hyperosmotic salinity response, and shoot development. Its product localizes to the Golgi cis, medial, and trans cisternae, Golgi membrane, trans-Golgi network, endosome, and extracellular space. Associations with root mass density and root morphology traits have been noted. Related genes in other species link the family to beta1,2-xylosyltransferase activity.
