Natural selection and recombination event of PvMSP-142. (A) Sliding window plot of nucleotide diversity per site (π) comparing the level of genetic diversity at PvMSP-142. The π values were calculated using DnaSP with a window length of 100 bp and step size of 25 bp. (B) The linkage disequilibrium (LD) plot showing non-random association between nucleotide variants in the 149 Korean P. vivax isolates at different polymorphic sites. The R2 values were plotted against nucleotide distance using a two-tailed Fisher’s exact test for significance.
