KCS2 — Camelina sativa

Summary

CsKCS2 (CSA17G007360) on Camelina sativa chromosome 17 encodes a 3-ketoacyl-CoA synthase, a member of the FAE1-type polyketide synthase family with acetoacetyl-CoA reductase, trans-2-enoyl-CoA reductase, ketoreductase, 3-hydroxyacyl-CoA dehydratase, and protein tyrosine phosphatase activities. It is associated with very-long-chain fatty acid metabolism and biosynthesis, wax and suberin biosynthesis, cuticle development, sphingolipid metabolism, trichome papilla formation and branching, pollen development, polar cell growth, osmotic and wounding responses, and regulation of cell division and developmental growth. The gene is linked to drought and salt tolerance, high temperature stress response, root morphology and thickness, leaf composition, embryo development, plant male sterility, and cell elongation traits. It localizes to the endoplasmic reticulum membrane, fatty acid elongase complex, mitochondria, nucleus, and cytosol. Studies of related genes in other species connect the family to cuticular wax formation, pollen fertility, root hair elongation, and cell division.
