Figure 1 Genomic organization of Saccharomyces 20S RNA narnavirus (ScNV-20S) and Saccharomyces 23S RNA narnavirus (ScNV-23S) and the proteins encoded on them (p91 and p104, respectively). Sequence motifs (A to D) conserved in RdRp are boxed and shaded. Motifs 1, 2 and 3 are present only in p91 and p104.
Figure 2 Phylogenetic tree based on aa sequences of motifs A to E (Hong et al. 1998) of the putative RdRp proteins of members of the family Narnaviridae, other families of RNA viruses of fungi and related viruses in other host taxa, and the family Leviviridae of RNA bacteriophages. Sequence alignments and the neighbor-joining tree were made using the Clustal X program. Bootstrap numbers (1000 replicates) are shown on the nodes. Abbreviations and sequence acquisition numbers are: AbVL1, Agaricus bisporus virus L1 X94361; AhV, Atkinsonella hypoxylon virus L39126; BaYMV, Barley yellow mosaic virus D01091; BcV3, Beet cryptic virus 3 S63913; CHV1, Cryphonectria hypovirus 1 M57938; CMV1, Cryphonectria mitovirus 1 L31849; FusoV1, Fusarium solani virus 1 D55668; GlV, Giardia lamblia virus L13218; GMVS1, Gremmeniella mitovirus S1 AF534641; Hv145SV, Helminthosporium victoriae 145S virus AF297176; Hv190SV, Helminthosporium victoriae 190S virus U41345; LRV1, Leishmania RNA virus 1-1 M92355; MBV, Mushroom bacilliform virus U07551; MS2, Enterobacteria phage MS2 GB-PH:MS2CG; OMV3a, Ophiostoma mitovirus 3a AJ004930; OMV4, Ophiostoma mitovirus 4 AJ132754; OMV5, Ophiostoma mitovirus 5 AJ132755; OMV6, Ophiostoma mitovirus 6 AJ132756; PcV, Penicillium chrysogenum virus AF296439; PLRV, Potato leafroll virus X14600; Qbeta, Enterobacteria phage Qβ AY099114; RVM2, Rhizoctonia virus M2 U51331; ScV-L-A, Saccharomyces cerevisiae virus L-A J04692; ScV-L-BC, Saccharomyces cerevisiae virus L-BC U01060; ScNV-20S, Saccharomyces 20S RNA narnavirus M63893; ScNV-23S, Saccharomyces 23S RNA narnavirus M86595; TEV, Tobacco etch virus M15239; TvV, Trichomonas vaginalis virus U08999; UmVH1, Ustilago maydis virus H1 U01059.
