Recombination breakpoints distribution throughout ORF sequences of Southeast Asia endemic Foot-and-mouth disease virus (FMDV) lineages. Based on the recombination points found, nine recombination-free regions (r1–9) were found within the FMDV genomes analyzed. The y-axis represents the number of recombination breakpoints detected within a 300 nt sliding window. The x-axis represents the nt position across the genome (reference for nt position: sequence O/JPN/2000-AB079061).
