G2 — Sorghum bicolor

Summary

SORBI_3004G086800, designated SbG2 on sorghum chromosome 4, encodes a 3-ketoacyl-CoA synthase (EC 2.3.1.199) with tetraketide alpha-pyrone synthase and elongase activity, belonging to the FAE1-type polyketide synthase family. The gene is associated with wax and fatty acid anabolism, polyketide anabolism, anthocyanin anabolism, pigmentation, pollen wall assembly, UV protection, nitrogen fixation, and nitric oxide storage. Its product localizes to membranes. Studies of related genes in other species link the family to additional polyketide functions.
