Abstract

Some isolates of Epichloë festucae are asymptomatically infected by Epichloë festucae virus 1 (EfV1), a member of the family Totiviridae. This virus has a genome composed by a 5109 bp molecule of double stranded RNA (dsRNA). In addition, a 3 kbp dsRNA molecule which could be the genome of another virus (EfV2) was frequently found in isolates of the fungal endophyte. In a survey of two populations of E. festucae it was found that 73% of the isolates were infected by one or both viruses. Although both viruses are very efficiently transmitted to conidia, a barrier to virus transmission occurs during ascospore formation. Keywords: Epichloë festucae, virus, dsRNA, Totivirus
