G2 — Brachypodium distachyon

Summary

BdG2 (BRADI_3G56970V3) on Brachypodium distachyon chromosome 3 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 trihydroxybenzophenone synthase, tetrahydroxybenzophenone synthase, acetoacetyl-CoA reductase, trans-2-enoyl-CoA reductase (NADPH), ketoreductase, 3-hydroxyacyl-CoA dehydratase, naringenin-chalcone synthase, acyltransferase and other activities. The gene is associated with very-long-chain fatty acid and wax biosynthesis, suberin and cutin development, fatty acid elongation, polyketide and sphingolipid metabolism, and responses to UV, cold and osmotic stress. It has been linked to traits including drought and salt tolerance, manganese sensitivity, leaf vein morphology, male sterility, seed coat color, flowering time, root thickness and mass, cell elongation, chloroplast development, and high temperature stress response. Localisation evidence places the product at the endoplasmic reticulum membrane, fatty acid elongase complex, cell wall, chloroplast membranes, mitochondria and cytosol. Studies of related genes in other species connect the family to cuticular wax deposition, pollen fertility, root hair elongation and grain weight.
