IDS4 — Brassica oleracea var. botrytis

Summary

BoIDS4, located on chromosome 4 of cauliflower (Brassica oleracea var. botrytis), encodes a prenyl diphosphate synthase with geranyltranstransferase, farnesyltranstransferase, and dimethylallyltransferase activities, functioning as an all-trans-nonaprenyl-diphosphate synthase. This gene is associated with the biosynthesis of geranylgeranyl diphosphate, farnesyl diphosphate, and geranyl diphosphate, as well as isoprenoid, terpenoid, carotenoid, plastoquinone, and ubiquinone anabolism. It has been linked to responses to herbivores, insects, jasmonic acid, and salicylate, and to photosynthetic rate. The encoded protein localizes to the plastid, chloroplast stroma and thylakoid membrane, endoplasmic reticulum, and mitochondria. Studies of related genes in other species connect the family to leaf shape, meristem identity, and photochemical quenching.
