Phylogenetic analysis of vertically transmitted psyllid endosymbionts (Candidatus Carsonella ruddii) based on atpAGD and rpoC:: Comparisons with 16S-23S rDNA-derived phylogeny

Psyllids are insects that harbor endosymbionts (Candidatuus Carsonella ruddii) within specialized cells found in the insect's body cavity. Previous phylogenetic analyses based on endosymbiont 16S-23S ribosomal DNA and a host gene were concordant (M.L. Thao, et al., Appl. Env. Microbiol. 66:2898, 2000), Additional analyses with atpAGD and rpoBC gave similar frees showing the agreement expected from organisms that evolve through vertical transmission with no gene exchange.
