Describe how plant viruses are transmitted

WebIn nature plant viruses are mechanically transmitted from diseased to healthy plants by rubbing leaves together, injecting plant extract, by action of animals, etc. Viral particles remain adhered to plant surfaces, epidermis or hairs. During rubbing the cells are broken and viral particles are liberated in the damaged cells. WebDescribe the replication process of plant viruses All viruses depend on cells for reproduction and metabolic processes. By themselves, viruses do not encode for all of the enzymes necessary for viral replication. But within a host cell, a virus can commandeer cellular machinery to produce more viral particles.
