PEP — Solanum tuberosum

Summary

PGSC0003DMG400023576 (StPEP, also known as StPAS2 or StPAS2A) on potato chromosome 4 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 domain 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 the fatty acid elongase complex, ER membrane, and cell wall. Associations include plant male sterility, drought tolerance, high temperature stress response, salt tolerance, root morphology traits (root mass density, root thickness), trichome morphology, stomatal opening, leaf composition, and shoot apical meristem development. Studies of related genes in other species connect the family to cuticular wax formation, root growth, cell cycle control, and pollen fertility.
