Just so, how can we control plant viral diseases?
Plant viruses need to be transmitted by an organism-vector (insects, nematodes, zoosporic endoparasites) for their plant-to-plant spread. Hence, viral diseases can be efficiently controlled by limiting the populations of their vectors with the applications of appropriate pesticides.
Likewise, how do you make a plant virus free? So far, various methods have been established for eradication of plant viruses, including shoot tip culture (also called meristem culture) [2, 4, 11, 12, 19, 21, 23], micrografting [12, 21], chemotherapy [12, 17, 21], thermotherapy [2, 11, 19, 22, 23] and shoot tip cryotherapy [24, 25].
Also to know, how are plant viruses transmitted?
Most plant viruses are transmitted by insect vectors that cause damage to the plant and create an entry point for pathogens, or that tap into the phloem to feed. Once inside, viruses use the handful of genes in their tiny genomes to orchestrate the plant cells' machinery, while evading the plant's defenses.
How do plants fight viruses?
In plants and insects, a very effective way to combat a virus is through a process known as gene silencing. This mechanism treats a virus as a gene that is being expressed out of control. Thus, plant cells turn it off by dicing the viral RNA into small pieces.
