Why multipartite viruses infect plants rather than animals
(PHYSorg.com Physics)

Neither living nor non-living, viruses are generally strange. Among viruses, multipartite viruses are among the most peculiar-their genome is not packed into many particles rather than one. Multipartite viruses primarily infect plants rather than animals. A recent paper by researchers from Tokyo Institute of Technology (Tokyo Tech) uses mathematical and computational models to explain this observation.
