Transporters of secondary metabolites.
The membrane transport of plant secondary metabolites is a newly developing research area. Recent progress in genome and expressed sequence tag (EST) databases has revealed that many transporters and channels exist in plant genome. Studies of the genetic sequences that encode these proteins, and of phenotypes caused by the mutation of these sequences, have been used to characterize the membrane transport of plant secondary metabolites. Such studies have clarified that membrane transport is fairly specific and highly regulated for each secondary metabolite. Not only genes that are involved in the biosynthesis of secondary metabolites but also genes that are involved in their transport will be important for systematic metabolic engineering aimed at increasing the productivity of valuable secondary metabolites in planta.
