Green and blue values indicate pairwise per cent amino acid sequence identities of fusion and haemagglutinin-neuraminidase proteins of APMV serotypes,
respectively. The F and HN gene sequences used were taken from the genome sequences of respective APMV prototype strains; GenBank accession numbers cited
in the Fig. 3.8. The amino acid per cent identity was calculated using ClustalW alignment of protein sequences in MegAlign program of Lasergene software. Per cent
identity values from 50.0 and above are underlined.
c
Black values indicate pairwise evolutionary divergence estimates based on the complete coding sequences of fusion gene of avian paramyxovirus serotypes. The
number of base substitutions per site between sequences are shown. Standard error estimate(s) ranged from 0.026 to 0.068. All ambiguous positions were removed for
each sequence pair. Evolutionary analyses were conducted using the Kimura 2-parameter model (Kimura, 1980) in MEGA7 (Kumar et al., 2016).
