Figure 6. Phylogenetic analysis of all nucleotide sequences obtained from various countries, including China, Korea, Vietnam, India, Australia, and the United Kingdom.

Numbers on the nodes indicate clade credibility values. Previously reported sequence names are presented in the following format: strains-GenBank accession numbers. The tree reveals two clusters, the AC and AM genotypes. The bar represents a genetic distance of 0.01. CSBV is marked with a red box, the blue square represents that the AC genotype SBVs strains mainly were isolated from A. mellifera.
