How many plant viruses are there?
Since then, a large number of diverse viruses have been found in plants, animals, fungi, and bacteria. The current estimate of recognized viruses is approaching 4,000, of which about 1,000 are plant viruses. The main reason that we study plant viruses is the negative impact that viral diseases have on crop production.
Can virus live in plants?
Plant viruses are viruses that affect plants. Like all other viruses, plant viruses are obligate intracellular parasites that do not have the molecular machinery to replicate without a host.
How do plants control viral diseases?
Avoid working in the garden during damp conditions (viruses are easily spread when plants are wet). Avoid using tobacco around susceptible plants. Cigarettes and other tobacco products may be infected and can spread the virus. Remove and destroy all infected plants (see Fall Garden Cleanup).
