FMDV phylogenies. Five phylogenies were estimated from the five recombination-free alignments (A: P1; B: Lpro; C: P2; D: 3A–C; and E: 3D) under the maximum likelihood framework. The numbers on nodes are bootstrap clade support values, shown for various distinct clades. Serotype (S) and geographical (G) information were mapped onto the trees (see Keys). Scale bars are in the units of nucleotide substitutions per site. The map (licence CC BY-SA 4.0) was created with mapchart.net.
