Phylogenetic tree of nucleotide sequences of the partial fusion gene fragment of Egyptian isolates (marked with a solid black circle) and the references strains from GenBank using neighbor-joining methods of Mega6 software.
Figure 4
Detailed phylogenetic tree of NDV genotype VII using partial nucleotide sequences of the NDV-F gene. Sequences obtained in this study are marked with solid black circles. The phylogenetic tree was computed in the MEGA 6 software using neighbor-joining method with 1000 bootstrap replicates using Kimura-2 parameter and nucleotide substitution model.
