KCS2 — Camelina sativa

Summary

CsKCS2 (CSA17G007350) on Camelina sativa chromosome 17 encodes a 3-ketoacyl-CoA synthase, a component of the fatty acid elongase complex with acetoacetyl-CoA reductase, trans-2-enoyl-CoA reductase (NADPH), ketoreductase, 3-hydroxyacyl-CoA dehydratase and protein tyrosine phosphatase activities. The gene is associated with very-long-chain fatty acid metabolism, wax and suberin biosynthesis, cuticle development, sphingolipid metabolism, trichome papilla formation and branching, polar cell growth, pollen development, osmotic and wounding responses, and regulation of cell division. It localises to the endoplasmic reticulum membrane, mitochondria, cytosol and nucleus. Associations include drought and salt tolerance, root morphology and thickness, plant male sterility, embryo development, leaf composition, high temperature stress response, and cell elongation traits. Studies of related genes in other species link the family to cuticular wax formation, pollen fertility, root hair elongation and cell division.
