Fig. 4From: Remnants of horizontal transfers of Wolbachia genes in a Wolbachia-free woodwaspMaximum likelihood tree. It was constructed with the protein sequence of ORF13 compared to similar protein sequences from arthropod and bacterial species. The branch indicated in red represents the position of ORF13 among other sequences. The two Wolbachia strains are named after their hosts as follows: wAna, Drosophila ananassae; wPol, Atemnus politusBack to article page
