| systematic relationships and cospeciation of bacterial endosymbionts and their carpenter ant host species: proposal of the new taxon candidatus blochmannia gen. nov. | the systematic relationships of intracellular bacteria of 13 camponotus species (carpenter ants) from america and europe were compared to those of their hosts. phylogenetic trees of the bacteria and the ants were based on 16s rdna (rrs) gene sequences and mitochondrial cytochrome oxidase subunit i (coi) gene sequences, respectively. the bacterial endosymbionts of camponotus spp. form a distinct lineage in the y-subclass of the proteobacteria. the taxa most closely related to these bacteria are e ... | 2000 | 11034499 |
