2.4 │ Sequence Analysis
Sequence alignments were assembled with other ALV-J referential sequences retrieved from the National Center for Biotechnology Information database (Table 1). Phylogenetic analysis was based on the neighbor-joining method with 1000 bootstrap replicates by MEGA ver. 5.1 (Tamura et al., 2007). The GenBank accession numbers of the strains used in this study are listed in Table 1.
