LSU — Capsicum annuum

Summary

CaLSU, the pepper (Capsicum annuum) gene on chromosome 4, encodes a protein with an isoprenoid synthase domain superfamily and possesses geranyltranstransferase, dimethylallyltransferase, and farnesyltranstransferase activities. It is associated with the biosynthesis of geranylgeranyl diphosphate, geranyl diphosphate, farnesyl diphosphate, and isoprenoid, carotenoid, and terpenoid metabolism. The gene is linked to fruit development, fruit color, photosynthetic rate, and responses to herbivores, insects, salicylic acid, and jasmonic acid. Its product localizes to plastids, chloroplast stroma, etioplasts, the endoplasmic reticulum, and mitochondria. Related genes in other species link the family to carotenoid biosynthesis and low light tolerance.
