Ursprung und Diversität von Baculoviren
Zusammenfassung der Projektergebnisse
The obtained results of the project can be considered as a milestone in the elucidation of the early evolution of baculoviruses and related so-called "non-occluded" baculoviruses or nudiviruses. For the phylogeny and evolution of baculoviruses the following main conclusions can be drawn form the project: • Different insect-specific dsDNA viruses, such as Heliothis zea virus -1 ( = HzNV-1), Gryllus bimaculatus NV and Oryctes rhinoceros NV shared a common ancestor and should be considered as members of the same genus or family of viruses, which need to be established by the International Committee on Taxonomy of Viruses (ICTV). • Therefore a new genus name (= Nudiviruses) comprising these three viruses is proposed to the scientific community. • Nudiviruses are phylogenetically related to baculoviruses. These viruses share a set of 15- 17 core genes, including structural genes and nucleotide metabolism, such as the DNA ploymerase and the subunits of the RNA polymerase. • viruses from different lineages (Baculoviruses and Nudiviruses, but eventually also including Nimaviruses and Salivary gland hypertrophy viruses) may form a super-group of phylogenetically related viruses sharing a common ancestor. • The proposed phylogeny of the baculoviruses and nudiviruses does not mirror the phylogeny of the insect hosts. Hence, the phylogenetic incongruence of viruses and their insect hosts suggests that host ecology rather than host phylogeny was the main driving force of nudivirus and baculovirus evolution.
