Phylogenetic relationships between RSNV genomic sequences. Maximum-likelihood (ML) phylogenetic trees were reconstructed with the sequences of the segments RNA1 and RNA2 of 16 RSNV isolates and without the recombinant regions. The trees were reconstructed using the PHYML-3.1 algorithm implemented in SEAVIEW v4.7 [39] under the best-fitted nucleotide substitution model (TN93+G) with gap treatment by pairwise deletion and with 100 bootstrap replications. The sequences clustering in the African and south African lineages are indicted in green and brown, respectively.
