Sequence and phylogenetic analysis of the S1 genome segment of turkey-origin reoviruses

Based on previous reports characterizing the turkey-origin avian reovirus (TRV) σB (σ2) major outer capsid protein gene, the TRVs may represent a new group within the fusogenic orthoreoviruses. However, no sequence data from other TRV genes or genome segments has been reported. The σC protein encoded by the avian reovirus S1 genome segment is the cell attachment protein and a major antigenic determinant for avian reovirus. The chicken reovirus...
