G2 — Brachypodium distachyon

Summary

BdG2 (BRADI_3G20850V3) in Brachypodium distachyon encodes a 3-ketoacyl-CoA synthase (EC 2.3.1.199) belonging to the FAE1-type polyketide synthase family, with a thiolase-like domain. This membrane-associated enzyme is linked to fatty acid anabolism, signal transduction, and root development, including lateral root formation. The gene is also associated with responses to UV-A, UV-B, and general UV radiation. Annotated associations connect BdG2 to seed coat color. Studies of related genes in other species further link the family to very-long-chain fatty acid elongation and cuticular wax biosynthesis, though these roles are not yet established in Brachypodium.
