The transmission rates of each dsRNA were different, and monosporic isolates harbouring different combinations of the original set of six dsRNAs were obtained. A 5196 bp dsRNA element was sequenced and represents the genome of Tolypocladium cylindrosporum virus 1 (TcV1), a new member of the genus Victorivirus in the Totiviridae family. This virus was transmitted to 81.4% of the conidia; in contrast, four dsRNAs of 3.1-3.7 kbp were transmitted only to 4.7% of the monosporic isolates obtained from the infected parental strain. These four dsRNAs did not show segregation during transmission, one of them was sequenced and encoded an RdRp, suggesting that the four molecules might represent the whole genome of a multipartite chrysovirus. A third possible virus with a genome of approximately 4.2 kbp was transmitted to 79.1% of the monosporic isolates produced by the infected strain. Ribavirin was used to cure T. cylindrosporum from viruses, and TcV1 was sensitive to this drug. All monosporic cultures derived from the infected strain treated with 80 and 100 μM concentrations of the drug were free of TcV1. This research was financed by project AGL2008-01159, granted by the Spanish Ministry of Education and Science.
