PEP — Pisum sativum

Summary

PsPEP (PSAT4G119600) on garden pea chromosome 4LG4 encodes a protein with very-long-chain 3-hydroxyacyl-CoA dehydratase activity and additional annotated enzyme functions including trans-2-enoyl-CoA reductase, acetoacetyl-CoA reductase, and protein tyrosine phosphatase activities. The product belongs to the Tyr_Pase-like_PTPLA domain family. PsPEP is associated with very-long-chain fatty acid metabolism and biosynthesis, sphingolipid metabolism, embryonic pattern specification, and cell polarization. It localises to the ER membrane, fatty acid elongase complex, and cell wall. The gene has been connected to plant male sterility, drought tolerance, salt tolerance, photosynthetic rate, chlorophyll content, root morphology traits, trichome morphology, and high temperature stress response. Studies of related genes in other species link the family to cuticular wax formation, pollen fertility, root hair elongation, and cell cycle control.
