Abstract

In Vietnam, lingzhi is mainly used for medicinal purposes with a high market value leading to the increasing production in recent years. However, the identification and classification of this fungus are inaccurate due mainly to morphological characteristics. In this study, the ITS-based DNA barcode was used to analyze the genetic composition of 10 commercial lingzhi genotypes collected from different regions across the country. The results show that there exists genetic diversity of 10 lingzhi samples. Based on Kimura 2-parameter model, the genetic distances among studied accessions range from 0.000 to 0.047. Seven of ten accessions were reclassified as G. lingzhi and three accessions were identified as G. lucidum. In addition, 19 nucleotide sites differed among fungal samples were also reported. There is a high potential of using ITS-based DNA barcode for the identification and classification as well as providing information on the genetic relationship between lingzhi varieties.
