From: Genetic characterization of a Marek’s disease virus strain isolated in Japan
Phylogenetic trees based on alignment of the UL36 genes from Kgs-c1 and MDV strains. The tree was generated using the minimum evolutionary algorithm with a bootstrap analysis of 1000 replicates. The UL36 genes from MDV strains used in the analysis described in Fig. 1 were compared. The UL36 genes used in this analysis were mainly classified into two clusters, North America and Eurasia. Numbers indicate bootstrap percentages (1000 replicates). The scale indicates divergence time
