PEP — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.3HG0329680 (HvPEP) encodes a very-long-chain 3-hydroxyacyl-CoA dehydratase (EC 4.2.1.134) and is a member of the Tyr_Pase-like_PTPLA family. The gene is associated with very-long-chain fatty acid and sphingolipid anabolism, suberin biosynthesis, cutin-based cuticle development, and fatty acid elongation. It is linked to cell polarization, differential growth, guard mother cell division, and regulation of cell cycle G1/S phase transition. HvPEP is associated with traits including drought tolerance, salt tolerance, high temperature stress response, respiration rate, photosynthetic rate, quantum yield, root mass density, root thickness, trichome morphology, plant male sterility, and meristem and embryo development. The protein localises to the ER membrane, fatty acid elongase complex, cell wall, chloroplast thylakoid membrane, and stress granules. Studies of related genes in other species link the family to cuticular wax production, very-long-chain fatty acid synthesis, cell cycle control, and nematode resistance.
