Sequence analysis of genome segments S4 and S8 of Mal de Río cuarto virus (MRCV): evidence that the virus should be a separate Fijivirus species
This is the first sequence-based characterization of Mal de Río Cuarto virus (MRCV), currently classified as a variant of Maize rough dwarf virus (MRDV) and exclusively found in South America. We sequenced and analyzed genome segments S4 and S8. MRCV S4 coded for a putative 131.67 kDa protein while...

| description | This is the first sequence-based characterization of Mal de Río Cuarto virus (MRCV), currently classified as a variant of Maize rough dwarf virus (MRDV) and exclusively found in South America. We sequenced and analyzed genome segments S4 and S8. MRCV S4 coded for a putative 131.67 kDa protein while MRCV S8 coded for a putative 68.26 kDa protein containing an ATP/GTP-binding motif. The 5' and 3' ends of MRCV segments, were 5'AAGUUUUU3' and 5'CAGCUnnnGUC3', respectively. Prediction of secondary structure of both segments coding strands showed that terminal regions were able to form structures that are proposed to be replication and packaging signals. MRCV S4 showed identity to members of Fijivirus as well as to two other genera of the Reoviridae family. MRCV S8 revealed identity with Rice black streaked dwarf virus (RBSDV) S8, MRDV S7, Oat sterile dwarf virus (OSDV) S9 and Nilaparvata lugens reovirus (NLRV) S7. While MRDV and RBSDV segments are highly homologous between each other, MRCV identity levels with them was considerably lower. We discussed the evolutionary relationships of MRCV to other Reoviridae, and based on phylogenetic analysis we proposed that although MRCV is related to MRDV, it could be regarded as a new species of the Fijivirus genus. |
