Common multiple dsRNAs are present in populations of the fungus Discula destructiva originating from widely separated geographic locations.
DsRNAs were detected in 85/108 isolates of Discula destructiva, the cause of dogwood anthracnose, collected in South Carolina, Idaho, and Alabama. The eastern isolates contained a greater diversity of dsRNA than did Idaho isolates, but most isolates, irrespective of state of origin, contained two small bands (ca. 1.5-2.5 kb) with sequence homology indicated by Northern hybridization. Differences in the banding patterns suggest that genetic diversity of dsRNA in D. destructiva is generated rapidly and that D. destructiva can be simultaneously infected by multiple dsRNA viruses.
