A tree detailing the relationships within the Alphaproteobacteria, focusing on the Rhodospirillales order. The alignment consisted of 9766 amino acids across 80 genes from 96 taxa and the phylogenetic tree was calculated under the LG substitution matrix using 100 bootstraps and 50 inferences to pick the best tree. All nodes had 100 % bootstrap support with the exception of the node marked with the orange dot. DPRB are bolded and in green. The scale bar indicates the branch length that correspond to 0.1 amino acid substitutions per site
