Fig. 3From: Genetic polymorphism of the extracellular region in surface associated interspersed 1.1 gene of Plasmodium falciparum field isolates from ThailandSliding window plot of nucleotide diversity (Pi) and amino acid polymorphism of SURFIN1.1 extracellular region in P. falciparum Thai isolates. Nucleotide diversity is plotted with a window length of 90 bp and step size of 3 bp (A) and the number of the amino acid residues at each amino acid position is plotted (B). A total of 31 sequences from Thai isolates were used. Nucleotide and amino acid positions are after the 3D7 line sequencesBack to article page
