Badnavirus (genus)
This genus contains "bacilliform DNA" plant viruses similar to the Commelina yellow mottle virus (ComYMV) which as been assigned to the species Badnavirus maculacommelinae. The symptoms consist mainly of chlorotic and necrotic leaf streaking, deformations and stunting. However, these are often only mild to moderately severe. The viruses infect various plants but the host range of an individual virus is often limited.
Transmission has been mainly reported during the vegetative propagation of plants and some species are seed transmitted. Leafsucking insects are also involved in transmission and these include mealybugs, whiteflies, aphids and leafhoppers. The genus includes economically important viruses like the Banana streak viruses or the Cacao swollen shoot disease.
The particles are small, non-enveloped and bacilliform (typically 30 x 130 nm). The genome is a circular, double stranded DNA, often with 3 open reading frames and 7200-7600 nucleotides.
For a review see Bhat et al. (2016).
Currently, the following species have been entered into the system:
