CPT — Lactuca sativa

Summary

LsCPT, encoded by the gene LSAT_V11C500284520 on chromosome 5 of garden lettuce (Lactuca sativa), is a prenyltransferase with IPPS, zFPS, dimethylallylcistransferase, rubber cis-polyprenylcistransferase, and dehydrodolichyl diphosphate synthase activities, belonging to the UPP_synth-like family. It is associated with polyprenol and dolichyl monophosphate anabolism, plastid membrane organization, virus-induced PTGS, and response to cold. The protein localizes to the chloroplast stroma, ER, mitochondria, and cytosol. LsCPT is linked to reduced long-chain polyisoprenoids and medium-chain-length polyprenol biosynthesis. Related genes in other species are associated with photosynthetic efficiency, chloroplast membrane dynamics, cold stress response, and polyisoprenoid synthesis, as well as traits such as plant height, chlorophyll content, and root yield.
