IDS3 — Brassica oleracea var. botrytis

Summary

BoIDS3, located on chromosome 9 of cauliflower (Brassica oleracea var. botrytis), encodes a prenyl diphosphate synthase with geranyltranstransferase, farnesyltranstransferase, dimethylallyltransferase, and all-trans-nonaprenyl-diphosphate synthase (geranyl-diphosphate specific) activities. The gene is associated with the biosynthesis of geranylgeranyl diphosphate, geranyl diphosphate, farnesyl diphosphate, and other isoprenoids, as well as with plastoquinone, ubiquinone, carotenoid, and terpenoid anabolism. It has been linked to responses to herbivores, insects, salicylic acid, and jasmonic acid. The encoded protein localizes to the chloroplast thylakoid membrane, chloroplast stroma, plastid, endoplasmic reticulum, and mitochondria, and is part of a polyprenyl diphosphate synthase complex. Related genes in other species connect the family to similar isoprenoid biosynthesis pathways.
