G2 — Brachypodium distachyon

Summary

Brachypodium distachyon gene BdG2 (BRADI_4G14937V3) 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, and 3-hydroxyacyl-CoA dehydratase activities. It is associated with very-long-chain fatty acid elongation and metabolism, wax and suberin biosynthesis, cuticle development, sphingolipid metabolism, and responses to UV and cold. The gene has been linked to traits including drought and salt tolerance, disease tolerance, flowering time, root morphology, leaf vein morphology, seed coat color, male sterility, and plant growth and development. 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 production, pollen fertility, and very-long-chain fatty acid synthesis.
