Brome mosaic virus
Bromus is a widespread genus of perennial herbaceous plants of the Gramineae family. Like other plants, it is also susceptible to viral infections. A brome mosaic viruse is a cause of mosaic disease. It is a small icosahedral virus with a diameter of 28-30 nm. When adsorbed to the surface of a freshly cleaved mica the virus formes a monolayer with an ordered structure with a period of about 30 nm.
