From: Metagenomic analysis uncovers novel hepadnaviruses and nackednaviruses

Novel avian hepadnaviruses. (A) Newly discovered avian hepadnaviruses. The scale bar represents substitutions per site. (B) Genomic profiles of representative novel avian hepadnaviruses. (C) Avian eHBVs. The schematic diagram illustrates the avian eHBVs, such as Blackbird-agel788-i, with flanking host genome sequences omitted. The ‘i’ indicates integration, and ‘*’ denotes a stop codon. Most eHBVs exhibit intact HBs genes and partially complete HBp genes. (D) Evolutionary relationships inferred from the HBp RT domain sequences of novel avian eHBVs. The tree was generated with MEGA12 using the Maximum Likelihood method with the Jones-Taylor-Thornton (JTT) model. Bootstrap support values are based on 1,000 replicates. Scale bar represents substitutions per site.
