Fig. 1: maximum likelihood tree based on 66 concatenated orthologous genes. In the right side, the tRNA isotype organisation (using the single-letter amino acid code) of the tRNA gene clusters from each genome is related to the tree branches. The gaps (- symbol) may not represent the actual distance between two adjacent tRNA genes, but the distance from the reference tRNA gene cluster. The green circles in the branches indicate bootstrap values ≥ 70.
