G2 — Brachypodium distachyon

Summary

Brachypodium distachyon gene BdG2 (BRADI_1G44840V3) on chromosome 1 encodes a protein with acyltransferase activity, including naringenin-chalcone synthase, trihydroxybenzophenone synthase, tetrahydroxybenzophenone synthase, and biphenyl synthase activities, and belongs to the FAE1-type polyketide synthase family. The gene is associated with polyketide, flavonoid, and fatty acid biosynthesis, malonyl-CoA and benzoyl-CoA metabolism, responses to UV, UV-A, and UV-B radiation, lateral root and root development, and signal transduction. Its product localizes to the membrane. BdG2 is also linked to seed coat color. Studies of related genes in other species connect the family to similar biosynthetic pathways.
