Abstract:The genus Polygonatum represents a wide geographical distribution, abundant resources, complex taxa and a long cultivation history, and they are considered to be important with the medicinal, economic, ornamental and cultural value. By taking advantage of the improvement of molecular biology, a variety of DNA-based molecular techniques have been developed valuable to the research in related fields of the genus Polygonatum. In this paper, we review the current status and progress of the genus Polygonatum using DNA-based technologies (such as molecular marker and DNA barcode), and propose future prospects in order to provide references for efficient protection and utilization of plant resources.
