Radial Bayesian phylogenetic tree depicting the inferred genetic relationship among fusion gene sequences for 180 APMV-1 isolates originating from samples collected from wild birds in North America. Posterior probability values for major clades are shown. Dendrograms for each major clade with complete tip labels and classification of individual sequences by taxonomic order of host and North American region of sample origin are provided as Figs. 4, 5, 6 and 7
