XTR2 — Brachypodium distachyon

Summary

BdXTR2 (BRADI_1G68590V3) on chromosome 1 of Brachypodium distachyon encodes a xyloglucan endotransglucosylase/hydrolase (XTH) family protein with endoxyloglucan transferase activity (EC 2.4.1.207). The product is associated with cell wall assembly, biogenesis and organization, as well as xyloglucan and sucrose metabolism, secondary cell wall biogenesis, phenylpropanoid anabolism, and homeostasis. It has been linked to phloem or xylem histogenesis, filament development, fruit development and ripening, and root development. The protein localizes to the apoplast, plant-type cell wall, extracellular region, and cytoplasm. Associations with lignin content, root length, tracheary element development, reduced stamen elongation with impaired self-pollination, and lower internode development have been noted. Studies of related genes in other species connect the family to leaf vein development, stamen filament growth, and self-pollination.
