Tobacco streak virus

Economically important crop hosts include peanuts, sunflower, soybean, cranberry, cotton, chickpea and mung beans.

Symptoms of TSV may include black streaks on stems and leaves, stunted growth, chlorosis, leaf mosaic, lodging, and deformed growing tips, to name a few.

[4] TSV purified from infected plants consists of a ss-RNA genome encapsulated by spheroid particles made up of coat protein subunits.

[4] The coat protein subunits play a key role in the life cycle of the virus.

Once the virus has penetrated into the host cells, it uncoats and releases its viral genomic RNA into the cytoplasm and expressed proteins replicate.

These conditions generally occur in warmer months but are dependent on rainfall and weeds in the field.

The best management practices are to maintain good sanitation, purchase certified seed, control insects that serve as vectors, and provide barrier crops.
