Phylogenetic position of the Wolbachia identified from Bemisia afer and B. tabaci putative species based on bacterial groEL gene sequences (491 sites). Wolbachia strains are characterized by the names of their host species. The tree was constructed using a GTR + G substitution model for Bayesian analysis. Bayesian posterior probabilities are shown on the branches. The sequence obtained in this study is shown in bold. The bar indicates a branch length of 0.1 substitutions/site. The names and sequence GenBank accession numbers are listed in Table 1 and Table A4.
