Genomic and ploidy manipulation for enhanced production of phyto-pharmaceuticals

Polyploidization is often accompanied by increased cell size and conspicuous changes in secondary metabolism. Where vegetative plant organs are the source of secondary metabolites, as is the case with most medicinal plants, ploidy manipulations such as direct chromosome doubling or allopolyploidization provide a rapid means to realize enhanced production of phyto-pharmaceuticals. Supported with prospective examples, this article illustrates the potential of genomic and ploidy manipulation to enhance the resourcing of pharmaceuticals of plant origin and suggests some appropriate strategies for optimum utilization.
