KCS2 — Camelina sativa

Summary

CsKCS2 (CSA14G005370) on Camelina sativa chromosome 14 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. The gene is associated with very-long-chain fatty acid metabolism and anabolism, wax anabolism, suberin biosynthesis, cutin-based 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 and fatty acid elongase complex. CsKCS2 is associated with drought and salt tolerance, high temperature stress response, root morphology and thickness, leaf composition, plant male sterility, embryo development, cell cycle and elongation traits, and cuticular wax biosynthesis with glossy stem and reduced root growth phenotypes.
