CPT — Beta vulgaris subsp. vulgaris

Summary

BvCPT (BVRB_5G102550) on sugar beet chromosome 5 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 chloroplast stroma, ER, mitochondria, and cytosol. BvCPT is linked to 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 connect the family to dolichol accumulation, photosynthetic efficiency, polyprenol and dolichol biosynthesis, cold stress response, and chloroplast membrane dynamics, as well as diterpenoid biosynthesis and photosynthesis.
