KCR1 — Camelina sativa

Summary

CsKCR1 (CSA07G033170) on Camelina sativa chromosome 7 encodes a protein belonging to the short-chain dehydrogenase/reductase (SDR) family, with acetoacetyl-CoA reductase, trans-2-enoyl-CoA reductase (NADPH), ketoreductase, 3-hydroxyacyl-CoA dehydratase, and protein tyrosine phosphatase activities. It is associated with very-long-chain fatty acid metabolism and anabolism, wax and suberin biosynthesis, cuticle development, sphingolipid metabolism, trichome branching and papilla formation, embryonic pattern specification, cell polarization, lateral root development, and osmotic and cytokinin responses. The gene is linked to traits including plant male sterility, drought and salt tolerance, root morphology and thickness, leaf composition, high temperature stress response, and cell elongation. It localizes to the endoplasmic reticulum, fatty acid elongase complex, cell wall, chloroplast thylakoid membrane, mitochondria, cytosol, and nucleus. Studies of related genes in other species connect the family to VLCFA biosynthesis, embryo development, pollen fertility, cuticular wax formation, and root hair elongation.
