The first full-length endogenous hepadnaviruses: identification and analysis.

ABSTRACT: In silico screening of metazoan genome data identified multiple endogenous hepadnaviral elements in the budgerigar (Melopsittacus undulatus) genome, most notably two elements comprising about 1.3 × and 1.0 × the full-length genome. Phylogenetic and molecular dating analyses show that endogenous budgerigar hepatitis B viruses (eBHBV) share an ancestor with extant avihepadnaviruses and infiltrated the budgerigar genome millions of years ago. Identification of full-length genomes with preserved key features like ε signals could enable resurrection of ancient BHBV.
