FAE1 — Camelina sativa

Summary

CsFAE1 (CSA10G007610) on Camelina sativa chromosome 10 encodes a 3-ketoacyl-CoA synthase of the FAE1-type polyketide synthase family, with biphenyl synthase and naringenin-chalcone synthase activities (EC 2.3.1.199). The protein localises to the endoplasmic reticulum and membrane. It is associated with fatty acid elongation, very-long-chain fatty acid metabolism, lipogenesis, polyketide and flavonoid anabolism, and seed development. The gene is linked to seed weight, seed oil content and composition, eicosenoic acid content, very-long-chain omega-7 fatty acid content, and trichome development. Related genes in other species are linked to erucic acid content, seed very-long-chain fatty acid accumulation, and wax ester accumulation. Distant sequence similarity links the family to grain yield, seed size, plant height, drought tolerance, and water use efficiency.
