Application progress of molecular markers in research in plants of Swertia L / 中草药

Swertia L. plants distributed widely in China, and favored with its outstanding medicinal value by the researchers. Molecular marker technology has been developing rapidly in recent years, as a kind of effective modern method. It was used widely in various fields of medicinal plants. The application status of the molecular markers including RAPD, SSR, ISSR and DNA barcoding on somatic hybridization, genetic diversity study, germplasm resources identification and phylogenetic analysis of Swertia L. were systematically reviewed in this paper for the first time, to provide reference for studies on Swertia L. and plants in other genus.
