Maximum likelihood phylogeny of MeSV and NeV samples. The phylogenetic inference of MeSV was based on a concatenated amino acid alignment of the conserved regions of the 3CLpro, RdRp and helicase domains (a). The phylogenetic inference of NeV was based on a concatenated amino acid alignment of the conserved regions of the methyltransferase, helicase and RdRp domains (b). The virus species identified in this study are marked with a red star. The bootstrap values represent 1000 replicates. The trees are drawn to scale, with branch lengths measured in the number of substitutions per site. MeSV, Mesoniviridae; NeV, taxon Negevirus
