مستخلص: In the present work, we report a novel mycovirus that infects Alternaria alternata. The mycovirus has isometric particles of approximately 30nm and the genome consists of two molecules of dsRNA, dsRNA1 with 1833bp, encoding a putative RNA-dependent RNA polymerase (RdRp) and dsRNA2, with 1680bp in length, encoding the putative capsid protein (CP). RdRp analysis revealed low amino acid identity with RdRps with species in the genus Gammapartitivirus, and the alignment of the RdRp revealed all the six conserved motifs present in members of Partitiviridae. The putative coat protein (CP) analysis revealed similarity with the putative CP of Botryosphaeria dothidea partitivirus 1 (BdPV1), a divergent partitivirus. We propose that Alternaria alternata partitivirus 1 (AtPV1) is a novel species and comprises a distinct lineage related to genus Gammapartitivirus in the family Partitiviridae, apparently on the threshold of radiation of a new genus, together with BdPV1. Vertical transmission tests showed that AtPV1 was transmitted to 100% conidial progeny and standard curing was unable to eliminate it from the host, characterizing it as a persistent virus. The absence of a virus-free isogenic lineage prevented us from accessing the details of the interaction between AtPV1 and A. alternata. Therefore, it remains unclear whether the morphological plasticity observed or the inability of the A. alternata isolate AVi1 to cause disease in plants is associated with AtPV1 infection.
