Newly sequenced HBV-A genomes in this study. Midpoint rooted phylogenetic tree representing the diversity of the novel HBV-A sequences from this study. The sequences from our study are shown as enlarged tips on the phylogeny. Branches leading to taxa with a known subgenotype are colored by their subgenotype. Out of a total of forty-seven new genomes, we introduce twenty-nine genomes that cluster most closely with subgenotype 1. Additionally, we introduce one genome that falls within subgenotype 2, nine new genomes that lie within the diversity of subgenotype 3, two genomes that cluster with subgenotype 5, and six genomes that cluster most closely with subgenotype 6. Branches leading to ancient genomes have been pruned to preserve scale.
