G2 — Brachypodium distachyon

Summary

Brachypodium distachyon gene BdG2 (BRADI_3G07730V3) encodes a protein with domains including ACP_syn_III_C, 3-ktacl-CoA_syn, FAE1_typ3_polyketide_synth, and Thiolase-like, and has annotated molecular functions including acetoacetyl-CoA reductase activity, trans-2-enoyl-CoA reductase (NADPH) activity, 3-hydroxyacyl-CoA dehydratase activity, and others. It is associated with very-long-chain fatty acid biosynthesis and elongation, wax and suberin biosynthesis, cuticle development, sphingolipid metabolism, and responses to UV, cold, and osmotic stress. The gene has been linked to traits including drought and salt tolerance, manganese sensitivity, leaf vein morphology, male sterility, seed coat color, flowering time, root morphology, and disease tolerance. It localizes to the endoplasmic reticulum, fatty acid elongase complex, cell wall, chloroplast membranes, and mitochondria. Studies of related genes in other species connect the family to cuticular wax deposition, pollen fertility, root suberin biosynthesis, and grain weight.
