Geographic and genetic diversity of edible Tylopilus griseipurpureus in Vietnam’s Acacia hybrid plantations
Main Article Content
Abstract
An edible Tylopilus species has long been recorded in the Acacia plantation forests in Vietnam and is widely traded in local markets. In this study, mushroom specimens associated with Acacia plantations were collected from different geographical regions across Vietnam for analysis. Morphological examinations and phylogenetic analyses based on internal transcribed spacer (ITS) and nuclear large ribosomal subunit (nrLSU) sequence data confirmed that these specimens belong to Tylopilus griseipurpureus. The genetic diversity among 19 T. griseipurpureus specimens from across Vietnam was further investigated using inter-simple sequence repeat (ISSR) markers.
