The RdRp domains of putative mitoviruses identified in R. solani DC17 and recognized members of the genus mitovirus [8] were aligned using MEGA 6.06 and the sequence alignment algorithm MUSCLE [47]. Conserved motifs A-F were marked according to Bruenn 2003, Černý et al. 2014, Koonin et al. 1993, Boehr et al. 2014 and Xu et al. 2003 [32, 36, 44–46]. CpMV-1, Cryphonectria parasitica mitovirus (NP_660174.1); OMV-3a, Ophiostoma mitovirus 3a (CAJ32468.1); OMV-4, Ophiostoma mitovirus 4 (NP_660179.1); OMV-5, Ophiostoma mitovirus 5 (NP_660180.1); OMV-6, Ophiostoma mitovirus 6 (NP_660181.1), RsMV-9, Rhizoctonia solani mitovirus 9 DC17 (KX349058); RsMV-16, Rhizoctonia solani mitovirus 16 (KX349057); RsMV-17, Rhizoctonia solani mitovirus 17 (KX349059); RsMV-18, Rhizoctonia solani mitovirus 18 (KX349060); RsMV-19, Rhizoctonia solani mitovirus 19 (KX349056); RsMV-20, Rhizoctonia solani mitovirus 20 (KX291005). Shading indicates level of conservation and the consensus sequence is displayed.
