Endogenous Viral Elements in Animal Genomes

Genetic structures and phylogenetic relationships of EVEs related to flaviviruses and hepadnaviruses.

(a) Genetic structures of non-overlapping flavivirus EVEs in the Aedes aegyptii genome. (b) Phylogenetic relationship of consensus flavivirus EVE sequences (spanning most of the region shown in (a) with exogenous and endogenous flaviruses. (c) Genetic structures of non-overlapping rtDNA (hepadnavirus) EVEs shown relative to the genus type species. Numbers to the left indicate the T. guttata chromosome on which the EVE is present. (d) Phylogenetic relationships of consensus zebrafinch EVEs and representative exogenous viruses. Avihepadnavirus genus is rooted on Woodchuck HBV (Orthohepadnavirus). All ML phylogenetic trees were inferred from amino acid alignments using the best-fitting model of evolution. Support for trees was evaluated using 1,000 nonparametric bootstrap replicates. Abbreviations: KRV = Kamiti River virus, HBV = hepatitis B virus, dHBV = duck hepatitis B virus.
