Patterns of nucleotide diversity and natural selection on Pvs48/45. a Schematic diagram of Pvs45/48 gene showing positions of 12 SNPs (black bars) identified in the Chinese isolates. Symbols above bars represent SNPs observed in each population. The singletons have been highlighted in red. b Sliding window analysis of average pairwise nucleotide diversity (π). c dn/ds calculated using 200 P. vivax isolates. A window size of 100 bp and a step size of 25 bp were used for the window plot analysis
