PEP — Brassica napus

Summary

BnPEP (DARMORV10_C03P05130.1) on chromosome C03 of oilseed rape encodes a protein with very-long-chain 3-hydroxyacyl-CoA dehydratase activity, a component of the fatty acid elongase complex. It is associated with very-long-chain fatty acid metabolism, sphingolipid anabolism, wax and suberin biosynthesis, and cuticle development. The gene is linked to cell polarization, embryonic pattern specification, symmetric cell division, and regulation of the cell cycle G1/S phase transition. Traits connected to BnPEP include drought tolerance, salt tolerance, high temperature stress response, plant male sterility, root mass density, root thickness, trichome morphology, leaf composition, and shoot apical meristem development. Studies of related genes in other species link the family to cuticular wax formation, pollen fertility, cell cycle control, and root hair elongation.
