Phylogenetic tree based on the nucleotide sequences of the fusion gene (A) (nt 1–1662) and hemagglutinin-neuraminidase gene (B) (nt 1–1713 or 1731) of NDV.

Abstract

<p>The phylogenetic tree was constructed by the Neighbor-Joining method with 1000 bootstrap replicates (bootstrap values are shown on the tree).</p
