Phylogenetic analysis of Pleurotus species

Phylogenetic analysis of Pleurotus species We performed phylogenetic analysis for ten Pleurotus species, based on internal transcribed spacer (ITS) sequences of rDNA. A phylogenetic tree was constructed on the basis of 31 oyster fungi strains of different origin and 10 reference sequences from GenBank. Our analysis demonstrates that the tested Pleurotus species are of monophyletic origin. We evaluated the evolutionary distances between these species. Classic genetic analysis of sexual compatibility based on monokaryon mon-mon crosses showed no reproductive barriers within the P. cornucopiae-P. euosmus species complex. Thus, despite the divergence (subclustering) between commercial strains and natural isolates of P. ostreatus revealed by phylogenetic analysis, there is no reproductive isolation between these groups. A common allele of the matB locus was identified for the commercial strains Sommer and L/4, supporting the common origin of these strains. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

We performed phylogenetic analysis for ten Pleurotus species, based on internal transcribed spacer (ITS) sequences of rDNA. A phylogenetic tree was constructed on the basis of 31 oyster fungi strains of different origin and 10 reference sequences from GenBank. Our analysis demonstrates that the tested Pleurotus species are of monophyletic origin. We evaluated the evolutionary distances between these species. Classic genetic analysis of sexual compatibility based on monokaryon mon-mon crosses showed no reproductive barriers within the P. cornucopiae-P. euosmus species complex. Thus, despite the divergence (subclustering) between commercial strains and natural isolates of P. ostreatus revealed by phylogenetic analysis, there is no reproductive isolation between these groups. A common allele of the matB locus was identified for the commercial strains Sommer and L/4, supporting the common origin of these strains.
