(a) Genome organization of CawYV-RNA1 and -RNA2. Each of RNAs 1 and 2 contain a single large open reading frame (in blue). The predicted putative peptides are shown in green, separated by the predicted cleavage site (H/S) (red). The RNA1 polyprotein contains X1 protein, protease cofactor (Pro-cof/X2), helicase (Hel), viral protein genome-linked (VPg), protease (Pro) and RNA-dependent RNA polymerase (RdRP). RNA2 encodes for a polyprotein with hypothetical protein (HP), movement protein (MP) and capsid protein (CP). The conserved nepovirus sequences (domains and motifs) are shown in violet. The protease-polymerase (Pro-Pol) region of CawYV-RNA1 starts with the serine (S) of the protease motif and ends with the (GDD) motif of the polymerase (shown in gold). (b) Maximum-likelihood (ML) phylogenetic trees showing the relationships between CawYV and members of the genus Nepovirus based on aa alignments of the Pro-Pol region and (c) the capsid protein (CP) region. Numbers on branches indicate the bootstrap percentages (1000 replicates, ≥50% are shown). Tomato torrado virus (genus Torradovirus, family Secoviridae) is an outgroup
