G2 — Brachypodium distachyon

Summary

Brachypodium distachyon gene BdG2 (BRADI_2G16050V3) 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 acetoacetyl-CoA reductase, trans-2-enoyl-CoA reductase, ketoreductase, 3-hydroxyacyl-CoA dehydratase, and ELOVL activities. It is associated with very-long-chain fatty acid anabolism and metabolism, fatty acid elongation, wax anabolism, suberin biosynthesis, cutin-based cuticle development, sphingolipid metabolism, and response to UV and cold. The gene is linked to traits including drought tolerance, salt tolerance, manganese sensitivity, osmotic response sensitivity, abscisic acid sensitivity, high temperature stress response, oxidative stress response, disease tolerance, flowering time, leaf vein morphology, seed coat color, root morphology, plant male sterility, and chloroplast development. It localizes to the fatty acid elongase complex, ER membrane, cell wall, chloroplast membranes, and mitochondria. Studies of related genes in other species connect the family to cuticular wax production, pollen fertility, root suberin biosynthesis, and very-long-chain fatty acid synthesis.
