Viruses are the smallest pathogens of multiple diseases of humans, animals and plants. Viruses consists of a DNA or RNA molecule and a capsid shell. Despite the presence of genetic material, the replication of the virus outside living cell is impossible. Barley stripe mosaic virus ( BSMV) is a rod-shaped virus with a spiral capsid that infects forage and cereal plants. Crop losses due to the presence of BSMV are from 20 to 35% according to the different sources. Common symptoms for BSMV are yellow stripes and slow growth. It spreads through infected seed. The article describes the structural organization of the genome of the Barley stripe mosaic virus ( BSMV) and its identification. The structure of BSMV and functions of its proteins were considered. The description of symptoms of BSMV infection of cultivated and cereal plants are presented.
