    Abstract:
    Mal de Río Cuarto virus (MRCV) is a newly described species of the genus Fijivirus, family Reoviridae. The nucleotide sequence of four MRCV genome segments was determined. MRCV S1, S2, S3 and S6 were predicted to encode proteins of 168.4, 134.4, 141.7 and 90 kDa, respectively. MRCV S1 encodes a basic protein that contains conserved RNA-dependent RNA polymerase motifs, and is homologous to Rice black streaked dwarf virus (RBSDV), Fiji disease virus (FDV) and Nilaparvata lugens reovirus (NLRV) polymerases as well as to corresponding proteins of members of other genera of the Reoviridae. MRCV S2 codes for a protein with intermediate homology to the ones coded by RBSDV S4 and FDV S3 'B' spike, which is presumably the B-spike protein. MRCV S3 most probably encodes the major core protein and is highly homologous to corresponding proteins of RBSDV S2 and FDV S3. MRCV S6-encoded protein has low homology to the proteins of unknown function coded by RBSDV S6 and FDV S6. The identity levels between all analyzed MRCV coded proteins and their RBSDV counterparts varied between 84.5 and 44.8%. The analysis of the reported sequences allowed a phylogenetic comparison of MRCV with other reovirus and supported its taxonomic status within the genus.
