What causes yellow vein mosaic?
This disease is caused by a complex consisting of the monopartite begomovirus Bhendi yellow vein mosaic virus (BYVMV, family: Geminiviridae) and a small satellite DNA beta component. BYVMV can systemically infect bhendi upon agroinoculation but produces only mild leaf curling in this host.

THE TOBACCO MOSAIC VIRUS
Tobacco mosaic virus causes a mottled browning of tobacco leaves, and accordingly is of major economic importance. It also infects other crops, most notably tomatoes. The virus is spread mechanically from infected plants to scratched or damaged leaves of normal plants.
Which plant disease is caused by virus?
|Rank||Virus||Author of virus description|
|1||Tobacco mosaic virus (TMV)||Karen-Beth G. Scholthof|
|2||Tomato spotted wilt virus (TSWV)||Scott Adkins|
|3||Tomato yellow leaf curl virus (TYLCV)||Henryk Czosnek|
|4||Cucumber mosaic virus (CMV)||Peter Palukaitis|
Does mosaic virus live in soil?
Unlike TMV (tobacco mosaic virus), CMV is not seedborne in tomato and does not persist in plant debris in the soil or on workers’ hands or clothing. The occurrence of this virus is erratic and unpredictable; consequently, control of this disease can be difficult.
Can you eat a watermelon with mosaic virus?
