Chrysoviruses (Chrysoviridae) - General Features and Chrysovirus-Related Viruses

Abstract The family Chrysoviridae encompasses viruses with isometric particles, 35–40 nm in diameter, and multipartite double-stranded RNA genomes. The family was recently reorganized to accommodate two genera, Alphachrysovirus and Betachrysovirus, which infect fungi and are also associated with plants and insects. Chrysoviruses are transmitted intracellularly; both vertically from parent to offspring and horizontally from one isolate to another, and may cause hypovirulence in their fungal hosts.
