Phylogenetic relationship of the M segment polyprotein of the Mapputta Group viruses and other selected orthobunyaviruses.

<p>Relationship was inferred by Bayesian analysis of the protein sequence alignment. A WAG model of aa substitution with gamma+invariant site heterogeneity was used. Numbers represent Bayesian posterior probabilities (Maximum Likelihood Bootstrap values). Tomato spotted wilt virus (TSWV) has been included as an out-group. Tree is drawn to scale measured in substitutions/site as indicated by the scale bar.
