LSU — Capsicum annuum

Summary

CaLSU (T459_06286) 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, 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 etioplast, chloroplast thylakoid membrane, chloroplast stroma, plastid, endoplasmic reticulum, mitochondria and cytoplasm. Related genes in other species link the family to geranylgeranyl pyrophosphate biosynthesis and low light tolerance.
