PEP — Zea mays
Summary
ZM00001EB124340 (PEP, ZmPEP) on maize chromosome 3 encodes a very-long-chain 3-hydroxyacyl-CoA dehydratase (EC 4.2.1.134) and is a member of the Tyr_Pase-like_PTPLA domain family. The gene is associated with fatty acid elongation, C4 photosynthesis, bundle sheath cell differentiation, and sphingolipid metabolism. It has been linked to numerous agronomic traits including carbon isotope discrimination, water use efficiency, net photosynthetic rate, chlorophyll content, drought tolerance, salt tolerance, root mass density, root thickness, plant male sterility, and high temperature stress response. Localization evidence connects the product to the ER membrane, fatty acid elongase complex, chloroplast thylakoid membrane, and cell wall. Studies of related genes in other species link the family to very-long-chain fatty acid synthesis, cuticular wax production, cell cycle control, and nematode resistance.
