LSU — Capsicum annuum

Summary

CaLSU (T459_08056) on pepper chromosome 3 encodes a geranylgeranyl pyrophosphate synthase, chloroplastic, a prenyltransferase that catalyses the synthesis of geranylgeranyl diphosphate, farnesyl diphosphate and geranyl diphosphate. The gene is associated with isoprenoid, carotenoid, terpenoid and plastoquinone biosynthesis, as well as fruit development, responses to herbivores, insects, jasmonic acid and salicylate. It has been linked to fruit colour and photosynthetic rate. The encoded protein localises to the plastid, chloroplast stroma, etioplast, endoplasmic reticulum, mitochondria and cytoplasm. Studies of related genes in other species link the family to geranylgeranyl pyrophosphate and isoprenoid biosynthesis, and to low light tolerance.
