Tom Hill (postdoc) recently published a paper characterizing the genome of the Drosophila innubila Nudivirus (DiNV). These viruses are large (155kb), double-stranded, circular DNA viruses that appear to infect several members of the Drosophila genus. Tom found preliminary evidence that a few key genes are evolving adaptively in the virus. You can read the paper in Infection, Genetics and Evolution by clicking here.
