KCS2 — Camelina sativa

Summary

CsKCS2 (CSA02023S010) encodes a 3-ketoacyl-CoA synthase, a member of the FAE1-type polyketide synthase family with acetoacetyl-CoA reductase, trans-2-enoyl-CoA reductase (NADPH), ketoreductase, and 3-hydroxyacyl-CoA dehydratase activities (EC 2.3.1.199). The gene is associated with very-long-chain fatty acid metabolism and biosynthesis, wax and suberin biosynthesis, cutin-based cuticle development, and sphingolipid metabolism. It is linked to trichome papilla formation and branching, polar cell growth, pollen development, osmotic and wounding responses, and regulation of cell division. Associations with agronomic traits include drought and salt tolerance, root morphology and thickness, leaf composition, plant male sterility, and high temperature stress response. The protein localizes to the endoplasmic reticulum membrane and the fatty acid elongase complex. Studies of related genes in other species link the family to cuticular wax formation, pollen fertility, root hair elongation, and epidermal cell specificity.
