Genome architecture and phylogenetic position of Diplodia seriata splipalmivirus 1 (DsSpV1). (A) Schematic representation of the DsSpV1genome. The DsSpV1 genome has three segments encoding for split RdRP (P1 and P2) and a hypothetical protein (P3). While the RNA1 and RNA2 sequences were completely determined, the third segment, RNA3, has yet to be fully determined. (B, C) RdRP-based phylogenetic analysis of DsSpV1 and other splipalmiviruses (proposed family “Splipalmiviridae”) and narna, and narna-like viruses. The best fit model (LG+G+I+F for P1 and VT+G+F for P2) was selected as a substitution model for evaluating the phylogenetic relationships. The tree was rooted at mid-point, and classical narnaviruses formed an out-group (B, Figure 7 ).
