Genotype I phylogenetic tree constructed using the method of Neighbor-joining with 1000 bootstrap replications. Sequences of each genotype II, III and IV were used as outgroup. Branch lengths are proportional to percentage divergence. Tamura Nei (TrN+I+G) nucleotide substitution model was used with a proportion of invariable sites (I) of 0.5420 and gamma distribution (G) of 2.6122. The lineage and sub-lineages are marked. Amino acids changes are indicated on the tree. Bootstrap support values are shown for key nodes only.
