GPPS — Camelina sativa

Summary

CsGPPS (CSA06G037100) on Camelina sativa chromosome 6 encodes a prenyltransferase with geranyltranstransferase, dimethylallyltransferase, farnesyltranstransferase, and all-trans-nonaprenyl-diphosphate synthase (geranyl-diphosphate specific) activities, belonging to the polyprenyl synthetase family. The gene is associated with terpenoid and isoprenoid metabolism, including the biosynthesis of geranyl diphosphate, farnesyl diphosphate, geranylgeranyl diphosphate, carotenoids, plastoquinone, and ubiquinone. It is linked to responses to herbivores, insects, jasmonic acid, and salicylate, as well as embryo development ending in seed dormancy. The encoded protein localizes to the plastid, chloroplast stroma, and mitochondria, and is part of the polyprenyl diphosphate synthase complex. Studies of related genes in other species link the family to starch and sugar content.
