Figure 4From: Different linkages in the long and short regions of the genomes of duck enteritis virus Clone-03 and VAC StrainsEvolutionary relationship of US1, US2, US3 and US4 proteins in DEV S regions within the subfamily Alphaherpesvirinae. The phylogenetic tree was generated using the MEGALIGN (DNAStar) program. Sequence distances indicated by the scale were calculated using the Gonnet 250 matrix in LASERGENE.Back to article page
