Phylogenetic tree creased on the basis of the full-length HN gene of NDV isolates and reference strains. The accession numbers of the sequences derived in this study and those derived from GenBank were shown in Table 1. The tree was constructed using MEGA 4 neighbor-joining method with 1000 replicates of bootstrap. Genotype, sub-genotype and recently Chinese isolates are indicated on the right. ▲: Shaanxi NDV isolates
