[Systems biology applications to explore secondary metabolites in medicinal plants].
Secondary metabolites are produced during the growth and development of plants along with the adaptation of outer environment, as a rule they are the main active ingredients in medicinal plants and ensure the quality of crude drugs. Since biogenesis is quite complex, the production and accumulation of secondary metabolites are influenced by various biotic and abiotic factors either from gene or environments, the complexity may affect quality control of crude drugs and utilization of the active ingredients. The thought and approach adopted in systems biology is a powerful tool to explore biology fully, along with the development of modern molecular biology and information biology, omics integration like genomics, transcriptomics, proteomics, and metabolomics will bring new opportunities for the study of secondary metabolites of medicinal plant. It has great significance to apply this holistic and systematic method in researches on biosynthetic pathway, signal transduction, ecological environment and metabolic engineering of the formation of the secondary metabolites of medicinal plants, and in building secondary metabolite biosynthesis gene expression and regulation system model, in order to explain the origin of the active ingredients of medicinal plants, formation mechanism of the Chinese herbs, metabolic engineering effecting active ingredients of medicinal plants, and the rational exploitation and utilization of resources of medicinal plants systematically.
