Basic information and characterization of 28 HIV-1 B/B′ clones
Hollow circles (○) represent B strains from China; solid circles (●) represent B′ strains from China; hollow squares (□) represent reference B strains from Thailand; solid squares (■) represent reference B strains from Europe and America; hollow triangles (△) represent reference B strains from China; solid triangles (▲) represent subtype 01_AE_CN strains from China; hollow diamonds (◊) represent reference 08BC strains from China; and solid diamonds (♦) represent reference 07BC strains from China. The numbers on the nodes are bootstrap values, which indicate branch support on the phylogenetic tree. Only bootstrap values >80% are shown
