Sliding window plots of a Tajima’s D values, b Fu and Li’s D* values, c Fu and Li’s F* values, and d dN-dS values of the Pfs25 gene of Plasmodium falciparum. The X axis shows the midpoint of the contiguous windows of 25 bp with a step size of 3 bp for the portions of the genes sequenced (nucleotide positions of each gene are given as those in the allele of the reference genome strain 3D7 [45]). Significant D* and F* values, representing the windows with significant departures from zero, were detected at the same nucleotide positions 409 to 436, respectively. The red lines indicate P values of < 0.05. Bar shows regions corresponding to signal peptides (S), four EGF-like domains (D1 to D4), and transmembrane domain (A) in Pfs25
