Cartoon of idealized genome map of a filovirus showing known mammalian NIRVs and their two major clades. Shown are three gene regions of filovirus genomes that are known to have mammalian NIRVs. Red and blue colored boxes indicate phylogenetic clades. The bat cartoon indicates the gene region in Myotis that appears to have an open reading frame maintained.
