PEP — Solanum tuberosum

Summary

StPEP (PGSC0003DMG400016135) on potato chromosome 11 encodes a protein with very-long-chain 3-hydroxyacyl-CoA dehydratase activity (EC 4.2.1.134) and belongs to the Tyr_Pase-like_PTPLA family. The gene is associated with very-long-chain fatty acid metabolism, fatty acid elongation, sphingolipid metabolism, and cutin-based cuticle development. It has been linked to traits including drought tolerance, salt tolerance, high temperature stress response, plant male sterility, root mass density, root thickness, trichome morphology, stomatal opening, leaf composition, and shoot apical meristem development. Localization evidence connects the product to the fatty acid elongase complex, ER membrane, cell wall, and chloroplast thylakoid membrane. Studies of related genes in other species link the family to cuticular wax formation, pollen fertility, root hair elongation, cell cycle control, and nematode resistance.
