Genotype specific amino acid substitution in the deduced Fusion protein sequences.

*Genotype specific residue positions already reported (Yu et al., 2001).
aResidues at the indicated positions in classical genotype IV strains – Italian (EU293914) and Herts'33 (Ay741404).
bResidues at the indicated positions only in both the Indian and the classical genotype IV strains.
cResidues at the indicated positions found in genotype IV strains from India - NDV-2K3 (FJ986192) and NDV2 (GU187941) and not in the classical genotype IV virus.
• Eventhough the genotype XI strains groups in the same clade along with genotype IV there were several residues positions that were unique.
• Substitutions L69M and D82E reported for evolution of the genotype II (bold faced).
• The residue substitutions (V to A, A to V & D to N respectively) at positions 11, 402 & 479 respectively in Indian genotype IV strains are also observed in genotype II strains.
• Substitution V121I reported for the evolution of VIIb (bold italic).
