CPT — Beta vulgaris subsp. vulgaris
Summary
BvCPT (BVRB_7G172230) on sugar beet chromosome 7 encodes a prenyltransferase with IPPS, zFPS, dimethylallylcistransferase, rubber cis-polyprenylcistransferase, and dehydrodolichyl diphosphate synthase activities, belonging to the UPP_synth-like family. The gene is associated with polyprenol and dolichyl monophosphate anabolism, plastid membrane organization, and response to cold. Its product localizes to the chloroplast stroma, endoplasmic reticulum, and mitochondria. BvCPT is associated with root yield and sugar content, as well as reduced long-chain polyisoprenoids and medium-chain-length polyprenol biosynthesis. Studies of related genes in other species link the family to dolichol accumulation, photosynthetic efficiency, polyprenol synthesis, and cold stress response, while tomato relatives connect it to chloroplast membrane dynamics, photosynthesis, and diterpenoid biosynthesis.
