LSU — Capsicum annuum

Summary

CaLSU (T459_06288) on pepper chromosome 2 encodes a prenyl diphosphate synthase with all-trans-nonaprenyl-diphosphate synthase (geranyl-diphosphate specific), FGPP synthase, geranyltranstransferase, dimethylallyltransferase, farnesyltranstransferase and prenyltransferase activities. The gene is associated with geranylgeranyl diphosphate, geranyl diphosphate, farnesyl diphosphate, plastoquinone, ubiquinone, isoprenoid, carotenoid and terpenoid anabolism, as well as isoprenoid and carotenoid metabolism. It has been connected to fruit development, fruit color, photosynthetic rate, and responses to herbivores, insects, salicylate and jasmonic acid. The product localises to the plastid, chloroplast thylakoid membrane, chloroplast stroma, etioplast, endoplasmic reticulum and mitochondria, and is part of a polyprenyl diphosphate synthase complex. Studies of related genes in other species link the family to geranylgeranyl pyrophosphate biosynthesis and low light tolerance.
