PEP — Brassica napus

Summary

BnPEP (DARMORV10_C09P66790.1) on chromosome C09 encodes a protein with very-long-chain 3-hydroxyacyl-CoA dehydratase activity, belonging to the Tyr_Pase-like_PTPLA family. The gene is associated with very-long-chain fatty acid metabolism and anabolism, fatty acid elongation, sphingolipid metabolism, and cutin-based cuticle development. It is linked to wax and suberin biosynthesis, cell polarization, embryonic pattern specification, symmetric cell division, and regulation of meiotic nuclear division. Associations include plant male sterility, drought and salt tolerance, high temperature stress response, root morphology and thickness, trichome morphology, leaf composition, shoot apical meristem development, and cell cycle and cell elongation traits. The encoded product localizes to the fatty acid elongase complex, ER membrane, cell wall, and stress granule. Studies of related genes in other species link the family to cuticular wax formation, pollen fertility, root hair elongation, and cell cycle control.
