ICTV Virus Taxonomy Profile: Nanoviridae

 ICTV Virus Taxonomy Profile: Nanoviridae相片
Nanoviridae is a family of plant viruses (nanovirids) whose members have small isometric virions and multipartite, circular, single-stranded (css) DNA genomes. Each of the six (genus Babuvirus) or eight (genus Nanovirus) genomic DNAs is 0.9–1.1 kb and is separately encapsidated. Many isolates are associated with satellite-like cssDNAs (alphasatellites) of 1.0–1.1 kb. Hosts are eudicots, predominantly legumes (genus Nanovirus), and monocotyledons, predominantly in the order Zingiberales (genus Babuvirus). Nanovirids require a virus-encoded helper factor for transmission by aphids in a circulative, non-propagative manner. This is a summary of the ICTV Report on the family Nanoviridae, which is available at ictv. global/ report/ Nanoviridae (Dr. Hsin Hung Yeh currently serves as a member in the Nanoviridae Study Group, International Committee on Taxonomy of Viruses).
