XTH — Brachypodium distachyon

Summary

BdXTH24 (BRADI_1G01150V3) on chromosome 1 of Brachypodium distachyon encodes a xyloglucan endotransglucosylase/hydrolase (XTH) with endoxyloglucan transferase and O-glucosyl hydrolase activities, belonging to the GH16 family and containing a ConA-like domain. The gene is associated with cell wall biogenesis and organization, xyloglucan and sucrose metabolism, secondary cell wall formation, phenylpropanoid biosynthesis, fruit ripening, homeostasis, and root development. Its product localizes to the apoplast, plant-type cell wall, and cytoplasm. Associations with lignin content and root length have been noted. Related genes in other species link the family to xyloglucan remodeling and cell wall dynamics.
