Figure 5. — Phylogenetic analysis of deltaviruses. (a) Heat map of pairwise amino acid sequence identities between deltaviruses. (b) The phylogenetic tree was inferred by the maximum likelihood method using an amino acid sequence alignment of representative deltaviruses. Known phenotypes (RNA-editing and expression of the large isoform of DAg protein) and helper virus(es) of each virus are shown on the right. Note that the SDeV phenotypes are shown in gray letters, because there is insufficient information, evidence, or both for the RNA-editing and L-DAg expression. The deltaviruses identified in this study are indicated by the blue circles. Bootstrap values >70 are shown. SDeV: snake deltavirus, RDeV: rodent deltavirus.
