XTR2 — Brachypodium distachyon

Summary

BdXTR2 (BRADI_3G21337V3) on chromosome 3 of Brachypodium distachyon encodes a xyloglucan endotransglucosylase/hydrolase (XTH family, GH16 domain) with endoxyloglucan transferase activity (EC 2.4.1.207). The product localises to the apoplast, plant-type cell wall and cytoplasm. It is associated with cell wall assembly, biogenesis and organisation, xyloglucan metabolism, secondary cell wall biogenesis, phenylpropanoid anabolism, sucrose metabolism, and homeostasis. The gene has been linked to root development, filament development, phloem or xylem histogenesis, fruit development and ripening, and tracheary element development. Associations with reduced stamen elongation, impaired self-pollination, lower internode development, lignin content, and root length have also been recorded. Studies of related genes in other species connect the family to leaf vein development, stomatal resistance, stamen filament growth, and self-pollination.
