Fig. 1
Representation of pvron4 encoding DNA sequence and sliding window for ω rate. ron4 ω values (dN/dS) within P. vivax are shown in green throughout. Likewise, ω divergence rates (KN/KS) between the species infecting primates and P. vivax are shown in blue (for the species evolutionarily closest to P. vivax) and red (most distant). A representation of the ron4 gene is given below the sliding window indicating signal peptide (blue), the repeat region (black) and the putative esterase/lipase domain (purple). The P. vivax SNP positions are shown as discontinue lines, their numbering is based on Additional file 2 alignment. The sites under purifying selection within species are represented by light green lines and dark green between species while positively selected sites between species are shown by red lines
