Bamboo mosaic virus before that. The natural host of this virus is bamboo. It is known to infect at least 12 different species in 7 different genera. In host range studies it has been shown to cause local lesions on "Chenopodium amaraticolor" and "Gomphrena globosa" and a systemic infection in barley ("Hordeum vulgare"), another member of the grass family, "Poaceae" or "Gramineae". Symptoms in bamboo include chlorotic mottling/mosaic patterns on the leaves which run parallel with the veins (Typical symptoms on leaves), necrotic streaking on the shoots and stem abortion. However, not all susceptible plants show recognizable symptoms. Bamboo mosaic virus "Bamboo mosaic
Waikavirus cell. Replication follows the positive stranded RNA virus replication model. Positive stranded RNA virus transcription is the method of transcription. The virus exits the host cell by tubule-guided viral movement. Plants, poaceae, cyperaceae, and gramineae serve as the natural host. The virus is transmitted via a vector (insects). Transmission routes are vector and mechanical. Waikavirus Waikavirus is a genus of viruses in the order Picornavirales, in the family Secoviridae. Plants, poaceae, cyperaceae, and gramineae serve as natural hosts. There are currently three species in this genus including the type species Rice tungro spherical virus. Diseases associated with this genus include:
