Phylogenetic analysis of BevuMV1 sequences. RNA sequences were used, trimmed to shared termini as described in Materials and methods. Multiple sequence alignment was performed with MAFFT, followed by maximum-likelihood phylogenetic analysis with IQ-TREE. Results are displayed as a midpoint-rooted rectangular phylogram (scale bar, mean substitutions per nt position). Some branch tip labels indicate two or more BevuMV1 strains that have identical sequences (FB, fodder beet; SB, sugar beet; SC, Swiss chard; TB, table beet; WB, wild sea beet). Branch support values (shown in %) were calculated by ultrafast bootstrap method; branches with <50% support have been collapsed to the preceding node. BevuMV1 strains from sugar beet, table beet, or Swiss chard cultivars with Owen CMS mitochondria are labeled in red and orange; see text for further explanations. Apparent subclades of BevuMV1 strains are labeled at right (subclade I, viruses from B. vulgaris subsp. maritima; subclades IIa and IIb, viruses from B. vulgaris subsp. vulgaris).
