Molecular Taxonomy of Ganoderma cupreum from Southern India Inferred from ITS rDNA Sequences Analysis

摘要

Ganoderma is a cosmopolitan wood-rot basidiomycete that has been extensively studied for its pathogencity and medicinal properties. Identification of Ganoderma based on macro-microscopic features led to large number of synonyms which resulted in 250 taxonomic names. A Ganoderma species collected from Courtallam, Tamil Nadu was identified as G. cupreum . Phylogenetic analysis inferred from internal transcribed spacer rDNA region resolved the Indian isolate MYC1 as Ganoderma cupreum which clustered with Australian and Asian " cupreum " clade with 85% bootstrap support BS and shared 99% and 98% nucleotide similarity with Malaysian and Australian ' cupreum ' respectively. This study represents the first molecular evidence of G. cupreum from Asian origin.
