Figure 2From: Entire genome sequence analysis of genotype IX Newcastle disease viruses reveals their early-genotype phylogenetic position and recent-genotype genome sizePhylogenetic tree of NDV strains. Tree construction was done using the Neighbor Joining method with the maximum composite likelihood substitution model for partial F gene (nt 47-420) by program MEGA version 4 (Tamura, Dudley, Nei, and Kumar 2007). Divisions and genotypes are indicated by roman numerals. Sequences obtained from the current study are underlined.Back to article page
