SEN4 — Asparagus officinalis

Summary

A4U43_C05F35050, designated SEN4 (synonyms AoXTH12, AoXTH1, AoXTH2, AoXTH3, AoXTH5, XTR7, XTR6, XTR9, XTH19, XTH18, XTH17, XTH16) on asparagus chromosome 5, encodes a xyloglucan:xyloglucosyl transferase (EC 2.4.1.207) of the GH16/XTH family. This enzyme possesses endoxyloglucan transferase and O-glucosyl hydrolase activities, and binds polysaccharides. The gene is associated with xyloglucan catabolism and metabolism, cell wall assembly, biogenesis, organization, and secondary cell wall biogenesis, as well as lignin anabolism. It is linked to responses to salt, abscisic acid, and gibberellin stimulus, signal transduction, fruit ripening, and chlorophyll content. The encoded protein localizes to the apoplast, plant-type cell wall, and cytoplasm. Studies of related genes in other species connect the family to cell wall remodeling.
