G2 — Brachypodium distachyon

Summary

Brachypodium distachyon gene BdG2 (BRADI_3G26827V3) 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 other enzyme activities. It is associated with very-long-chain fatty acid anabolism and metabolism, wax anabolism, suberin biosynthesis, cutin-based cuticle development, sphingolipid metabolism, and fatty acid elongation. The gene has been linked to traits including drought tolerance, salt tolerance, oxidative stress response, high temperature stress response, abscisic acid sensitivity, flowering time, disease tolerance, manganese sensitivity, osmotic response sensitivity, leaf vein morphology, plant male sterility, seed coat color, root mass density, root thickness, chloroplast development, cell elongation, and plant growth and development. Localization evidence places the product at the ER membrane, fatty acid elongase complex, cell wall, chloroplast outer membrane, and mitochondria. Studies of related genes in other species connect the family to cuticular wax production, very-long-chain fatty acid synthesis, pollen fertility, and root hair elongation.
