Two new umbravirus-like associated RNAs (ulaRNAs) were found, respectively, in maize
and Johnsongrass samples from Ecuador. The complete sequences consist of 3,053 and
3,025 nucleotides, respectively, and contain four open reading frames (ORFs). Their
genome sequences were 58% identical to each other and 28 to 60% identical to the most
closely related viruses. Phylogenetic analysis using full genome sequences and amino acid
sequence of the RNA-dependent-RNA polymerase (RdRp) placed both sequences in a …

Two new umbravirus-like associated RNAs (ulaRNAs) were found, respectively, in maize
and Johnsongrass samples from Ecuador. The complete sequences consist of 3,053 and
3,025 nucleotides, respectively, organized in four open reading frames (ORFs). Genome
comparisons showed 58% identity between each other, whereas identities to the closest
related viruses ranged from 28 to 60%. Phylogenetic inferences using the full genome, or
the amino acid sequence of the RNA-dependent-RNA-polymerase (RdRp) placed both …
