BGAL1 — Brachypodium distachyon

Summary

BdBGAL1 (BGAL1) on chromosome 1 of Brachypodium distachyon encodes a protein with a glycoside hydrolase 35 catalytic domain and a lectin galactose-binding domain, and is annotated with beta-galactosidase activity, sugar binding, and transmembrane receptor protein serine/threonine kinase activity. The gene is associated with galactose breakdown, plant-type cell wall modification, phloem transport, leaf vascular tissue pattern formation, auxin signaling, and brassinosteroid-mediated signaling. It has been linked to leaf vein morphology, stem rust, trichome development, cell wall extension, xyloglucan structure, premature senescence with leaf cell death, abnormal leaf venation with reduced vein number, and vascular development. The protein localizes to the vacuole, apoplast, cell wall, extracellular region, plasmalemma, and nucleus. Related genes in other species are linked to cell wall polysaccharide modification and cell elongation.
