Medical vocabulary what does tungrovirus mean
Tungrovirus is a genus of viruses, in the family Caulimoviridae. Monocots and family Poaceae serve as natural hosts. There is currently only one species in this genus: the type species Rice tungro bacilliform virus. Diseases associated with this genus include: stunting, yellow to orange leaf discoloration with fewer tillers.

Taxonomy
Group: ssRNA-RT
Structure
Viruses in Tungrovirus are non-enveloped, with icosahedral and bacilliform geometries, and T=3 symmetry. Genomes are circular.
Life Cycle
Viral replication is nuclear/cytoplasmic. Replication follows the dsDNA(RT) replication model. The method of transcription is dsDNA(RT) transcription. Translation takes place by leaky scanning, and ribosomal shunting. The virus exits the host cell by nuclear pore export, and tubule-guided viral movement. Monocots and family poaceae serve as the natural host. The virus is transmitted via vectors such as aphids and leafhoppers (e.g. Nephotettix spp.).
