Abstract
Provided is a method for producing a polyisoprenoid, which makes it possible to synthesize in vitro a polyisoprenoid having an unprecedented structure, such as a 100% cis-polyisoprenoid or a polyisoprenoid containing an allylic diphosphate derivative as an initiating terminal. Also provided is a method for producing a polyisoprenoid in vitro, which employs a gene coding for a neryl diphosphate synthase and rubber particles bound to a protein encoded by the gene, or a method for producing a polyisoprenoid, which includes introducing into a plant a vector in which a gene coding for a neryl diphosphate synthase is linked to a promoter having a promoter activity that drives laticifer-specific gene expression to express a protein encoded by the gene specifically in laticifers.
