PEP — Brassica napus

Summary

BnPEP (DARMORV10_A03P04570.1) on chromosome A03 of oilseed rape encodes a protein with very-long-chain 3-hydroxyacyl-CoA dehydratase activity, a key component of the fatty acid elongase complex. It is associated with very-long-chain fatty acid metabolism and anabolism, as well as wax, cutin, suberin, and sphingolipid biosynthesis. The gene has been linked to cell polarization, embryonic pattern specification, symmetric cell division, guard mother cell division, and regulation of the cell cycle G1/S phase transition. Agronomically, BnPEP is associated with drought and salt tolerance, high temperature stress response, plant male sterility, trichome morphology, root mass density and thickness, leaf composition, and shoot apical meristem development. Studies of related genes in other species link the family to cuticular wax formation, pollen fertility, root hair elongation, and cell cycle control.
