Complete nucleotide sequences of the large RNA genome segments of Main Drain and Northway viruses (family Peribunyaviridae).

The large RNA genome segments of Main Drain virus (MDV) and Northway virus (NORV) were fully sequenced and shown to consist of 6860 and 6875 nucleotides, respectively. Sequence alignments revealed that the large RNA segment of MDV is most closely related to the corresponding region of NORV, with 76.8% nucleotide sequence identity, and the large RNA segment of NORV is most closely related to the corresponding region of Maguari virus, with 79.1% identity.
