The lineage-specific genetic varieties in non-structural and structural proteins of the CHIKV strains. Alignments of the amino acid sequences were performed to determine the consensus sequence. The consensus sequences from each genotype/lineage were aligned to screen the lineage-specific varieties. The amino acid positions with a difference of more than 1% were selected and the sites unrelated to lineages were removed. The lineage-specific genetic varieties in non-structural and structural proteins of the CHIKV strains are shown in panel a and b, respectively, with 72 and 107 mutational sites. The amino acid varieties in sites are represented by squares in different colors. The amino acid positions in each viral protein are listed by corresponding numbers. The undescribed mutational sites are marked in red squares and those previously described are marked in grey squares. CHIKV, chikungunya virus; WA, West African; A.re/CI, Asian reemerge/Caribbean Islands; A.old, Asian old; EA/SA, East/South African; CA, Central African; IOL, Indian Ocean lineage
