Abstract
Abstract
A novel double-strand RNA(dsRNA) mycovirus, named “Colletotrichum fioriniae alternavirus1(CfAV1)”, was isolated from the strain CX7 of Colletotrichum fioriniae, the causal agent of Walnut anthracnose. The complete genome of CfAV1 is composed of three dsRNA segments, dsRNA1(3528nt), dsRNA2(2485nt), and dsRNA3(2481nt). RNA-dependent RNA polymerase (RdRp) is encoded by dsRNA1, and dsRNA2 and dsRNA3, respectively, encode two hypothetical proteins. Based on multiple sequence alignments and phylogenetic analysis, CfAV1 was identified as a new member of the proposed family Alternaviridae. This is the first report of an alternavirus that infects phytopathogenic fungus C. fioriniae.
