Molecular genetics research of medicinal plants

: With the development of various biotechnology,the research on molecular genetics of medicinal plants has gradually deepened. In this paper,the research system of molecular genetics of medicinal plants was proposed for the first time,which was elaborated from the aspects of genetic resources,genome,gene function and research methods. The application fields of medicinal plant mainly contain species identification,molecular breeding and biosynthesis. The research directions of molecular genetics of medicinal plants in genetic resources,model platform,synthetic biology and molecular breeding were put forward,which include 1 000 genome projects of medicinal plants,model species and mutant libraries,gene original libraries of heterologous synthetic systems,construction gene original library and specific chassis cells in heterologous synthesis system of active ingredient,breeding of new varieties of medicinal plants with high active ingredient and high resistance based on molecular markers andtransgenes.
