CPT — Lactuca sativa
Summary
LsCPT, encoded by gene LSAT_V11C900491900 on chromosome 9 of garden lettuce (Lactuca sativa), is a prenyltransferase with IPPS, zFPS, 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, response to cold, and virus-induced post-transcriptional gene silencing. 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, root yield, lycopene content, sugar content, and stomatal resistance.
