The unique inducible system of protein secretion by the carnivorous pitcher plantSarracenia purpurea may be an ideal system for recombinant protein farming. S. purpurea is relatively uncommon and difficult to grow in vitro, so it has not been explored as a potential source of recombinant proteins. However, it naturally secretes large amounts of proteins into a liquid found in the leaf pitchers, so it may be an ideal way to collect recombinant proteins in leaf pitchers. Here, the advantages of transgenic S. purpurea systems over traditional transgenic plant systems for the production of recombinant pharmaceutical proteins are explored, and the steps necessary to produce such a system are discussed.
