Phylogenetic Analysis of Vertically Transmitted Psyllid Endosymbionts (Candidatus Carsonella ruddii) Based on atpAGD and rpoC: Comparisons with 16S–23S rDNA-Derived Phylogeny
- 252 Downloads
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 trees showing the agreement expected from organisms that evolve through vertical transmission with no gene exchange.
