Bromoviridae is a family of plant viruses with tripartite, positive-sense RNA genomes of about 8 kb in total. Genomic RNAs are packaged in separate virions that may also contain sub-genomic, defective or satellite RNAs. Virions are variable in morphology (spherical or bacilliform) and may be transmitted between hosts mechanically, via pollen, or non-persistently by insect vectors. Members of the family are responsible for major disease epidemics in fruit, vegetable and fodder crops such as tomatoes, cucurbits, bananas, fruit trees, common beans and alfalfa. Since the adoption of metagenomic high-throughput sequencing methodologies, there has been a notable increase in the number of species in the genus Ilarvirus. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Bromoviridae, which is available at ictv.global/report/bromoviridae.
