Detection and infection proportion of BbCV2 virus in B. bassiana strains, and analysis of genetic diversity from different collection sites. A dsRNA mycovirus detection of B. bassiana strains. Left: dsRNA extraction of all tested fungal strains; (+) = dsRNA from strains without DNase I and S1 nuclease treatment; (−) = dsRNA from strains with DNase I and S1 nuclease treatment. Right: detection of BbCV2 infection in B. bassiana strains by RT-PCR; (+) = original virus-infected B. bassiana strain of BbOFZK152 as positive control; (−) = original virus-free B. bassiana strain of BbOFDH-bar as negative control. B Proportion of BbCV2 infection in B. bassiana strains from different collection sites. C Nucleotide phylogenetic tree of virus BbCV2 collected from different regions and 32 mycoviruses
