G2 — Brachypodium distachyon

Summary

BdG2 (BRADI_2G15720V3) on chromosome 2 of Brachypodium distachyon encodes a protein with domains including ACP_syn_III_C, 3-ktacl-CoA_syn, FAE1_typ3_polyketide_synth, and Thiolase-like, and is annotated with enzyme activities including acetoacetyl-CoA reductase, trans-2-enoyl-CoA reductase, ketoreductase, 3-hydroxyacyl-CoA dehydratase, acyltransferase, and protein kinase activities, as well as EC 2.3.1.199. It is associated with very-long-chain fatty acid and polyketide anabolism, wax and suberin biosynthesis, cuticle development, sphingolipid metabolism, pollen tube development, trichome branching and papilla formation, response to UV-A and cold, and regulation of cell division. The gene is linked to traits including drought tolerance, salt tolerance, disease tolerance, manganese sensitivity, osmotic response sensitivity, abscisic acid sensitivity, high temperature stress response, oxidative stress response, flowering time, leaf vein morphology, root thickness and mass density, seed coat color, plant male sterility, and chloroplast development. Studies of related genes in other species connect the family to very-long-chain fatty acid biosynthesis, cuticular wax production, pollen fertility, root hair elongation, and grain weight.
