''. Poaceae plants serve as natural hosts. There are three species in this genus.


Taxonomy

The genus contains the following species: * '' Caladenia virus A'' * '' Sugarcane streak mosaic virus'' * '' Triticum mosaic virus''


Structure

Viruses in ''Poacevirus'' are non-enveloped, with flexuous and filamentous geometries. The diameter is around 12-15 nm, with a length of 680-750 nm. Genomes are linear and non-segmented, around 9.7-10.3kb in length.


Life cycle

Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host 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. Poaceae plants serve as the natural host. The virus is transmitted via a vector (wheat curl mite). Transmission routes are vector.
