phylogeny and molecular taxonomy of the bacillus subtilis species complex and description of bacillus subtilis subsp. inaquosorum subsp. nov. | the bacillus subtilis species complex is a tight assemblage of closely related species. for many years, it has been recognized that these species cannot be differentiated on the basis of phenotypic characteristics. recently, it has been shown that phylogenetic analysis of the 16s rrna gene also fails to differentiate species within the complex due to the highly conserved nature of the gene, yet dna-dna hybridization values fall well below 70 % for the same species comparisons. as a complementary ... | 2009 | 19622642 |
