Résumé
The genus Alternaria comprises many important fungal pathogens that infect a wide variety of organisms. In this report, we present the discovery of a new double-stranded RNA (dsRNA) mycovirus called Alternaria botybirnavirus 2 (ABRV2) from a phytopathogenic strain, XC21-21C, of Alternaria sp. isolated from diseased tobacco leaves in China. The ABRV2 genome consists of two dsRNA components, namely dsRNA1 and dsRNA2, with lengths of 6,162 and 5,865 base pairs (bp), respectively. Each of these genomic dsRNAs is monocistronic, encoding hypothetical proteins of 201.6 kDa (P1) and 2193.3 kDa (P2). ABRV2 P1 and P2 share 50.54% and 63.13% amino acid sequence identity with the corresponding proteins encoded by dsRNA1 of Alternaria botybirnavirus 1 (ABRV1). Analysis of its genome organization and phylogenetic analysis revealed that ABRV2 is a new member of the genus Botybirnavirus.
