PEP — Sorghum bicolor

Summary

SORBI_3003G071400, designated SbPEP (also known as SbPAS2), encodes a very-long-chain 3-hydroxyacyl-CoA dehydratase (EC 4.2.1.134) belonging to the Tyr_Pase-like_PTPLA family. The gene is associated with very-long-chain fatty acid and sphingolipid metabolism, suberin and cutin development, and cell polarization. SbPEP has been linked to grain weight, photosynthetic and respiration rates, drought and salt tolerance, root morphology, and heterosis. It is associated with trichome branching, guard mother cell division, and embryonic pattern specification. The encoded protein localizes to the ER membrane, fatty acid elongase complex, and stress granules. Studies of related genes in other species link the family to cuticular wax production, cell cycle control, and nematode resistance.
