PEP — Daucus carota subsp. sativus

Summary

DCAR_014186 (DcPEP, also known as DcPAS2 or DcPAS2A) on carrot chromosome 4 encodes a protein with very-long-chain 3-hydroxyacyl-CoA dehydratase activity, acetoacetyl-CoA reductase activity, trans-2-enoyl-CoA reductase (NADPH) activity, and protein tyrosine phosphatase activity, placing it in the Tyr_Pase-like_PTPLA domain family. The gene is associated with very-long-chain fatty acid metabolism, sphingolipid metabolism, suberin biosynthesis, cutin-based cuticle development, and fatty acid elongation. It has been linked to plant male sterility, drought tolerance, high temperature stress response, salt tolerance, root morphology traits including root mass density and thickness, trichome morphology, leaf composition, shoot apical meristem and embryo development, cell cycle and cell elongation traits, and auxin transport. Studies of related genes in other species link the family to cell cycle control, microtubule dynamics, cuticular wax formation, root hair elongation, and nematode resistance.
