Phylogenetic analysis of widely cultivated Ganoderma in China based on the mitochondrial V4-V6 region of SSU rDNA.
Ganoderma mushroom is one of the most prescribed traditional medicines and has been used for centuries, particularly in China, Japan, Korea, and other Asian countries. In this study, different strains of Ganoderma spp and the genetic relationships of the closely related strains were identified and investigated based on the V4-V6 region of mitochondrial small subunit ribosomal DNA of the Ganoderma species. The sizes of the mitochondrial ribosomal DNA regions from different Ganoderma species showed 2 types of sequences, 2.0 or 0.5 kb. A phylogenetic tree was constructed, which revealed a high level of genetic diversity in Ganoderma species. Ganoderma lucidum G05 and G. eupense G09 strains were clustered into a G. resinaceum group. Ganoderma spp G29 and G22 strains were clustered into a G. lucidum group. However, Ganoderma spp G19, G20, and G21 strains were clustered into a single group, the G. lucidum AF214475, G. sinense, G. strum G17, G. strum G36, and G. sinense G10 strains contained an intron and were clustered into other groups.
