Figure 1

Phylogenetic tree of the 26 NDV field isolates based on the full coding region of the HN gene. Reference sequences representing recognized genotypes were denoted with their taxon names underlined. The tree was generated using the neighbor-joining method implemented in program MEGA 4.0. The Class I NDV strain DE-R49/99 was served as an outgroup. The scale indicates the branch length based on the number of nucleotide substitutions per site and the numbers at nodes indicate bootstrap values calculated by resampling of 1000 replicates.
