Average incidences of synonymous, and non-synonymous and indel mutations in the codons of the coat protein (CP) gene of watermelon mosaic virus isolates subgroups: (A) EM1 isolates, (B) EM2 isolates, (C) EM5 isolates. The X-axis represents the position of the codon while the Y-axis represents the average cumulative number of synonymous, non-synonymous mutations estimated at specific codon positions in the CP gene. No indel was present in the CP of any WMV isolates in the three subgroups.
