CPT — Lactuca sativa
Summary
LsCPT, encoded by the gene LSAT_V11C500284510 on chromosome 5 of garden lettuce (Lactuca sativa), is a prenyltransferase with isopentenyl diphosphate synthase (IPPS), ZFPS, and rubber cis-polyprenylcistransferase activities. It is associated with polyprenol and dolichyl monophosphate biosynthesis, plastid membrane organization, virus-induced post-transcriptional gene silencing, and response to cold. The protein localizes to the chloroplast stroma, endoplasmic reticulum, mitochondria, and cytosol. This gene is associated with reduced long-chain polyisoprenoids. Studies of related genes in other species link the family to photosynthetic efficiency, chloroplast membrane dynamics, cold stress response, and traits including plant height, leaf shape, chlorophyll content, and root yield.
