CPT — Lactuca sativa

Summary

LsCPT, encoded by the gene LSAT_V11C300141970 on chromosome 3 of garden lettuce (Lactuca sativa), is a prenyltransferase with IPPS, zFPS, dimethylallylcistransferase, rubber cis-polyprenylcistransferase, and dehydrodolichyl diphosphate synthase activities. It belongs to the UPP_synth-like family and binds magnesium. The gene is associated with polyprenol and dolichyl monophosphate anabolism, plastid membrane organization, virus-induced PTGS, and response to cold. Its product localizes to the chloroplast stroma, endoplasmic reticulum, and mitochondria. LsCPT is linked to reduced long-chain polyisoprenoids and medium-chain-length polyprenol biosynthesis. Studies of related genes in other species connect the family to photosynthetic efficiency, chloroplast membrane dynamics, cold stress response, and traits including plant height, leaf shape, sugar content, and root yield.
