Objective:
Elucidate the medicinal licorice species circumscription in order to develop licorice resources in China and select new cultivars.
Method:
PCR amplification, DNA sequencing and cladistic analysis.
Result:
Acquire the ITS sequences and phylogenetic tree of 8 licorice species.
Conclusion:
According to results Glycyrrhiza eurycarpa and G. glabra var. glandulosa should be combined into G. and G. glabra respectively and G. egladulosa is an independent species.
