* they don’t have specific mechanism for entering the host plants. The injuries, insect vectors are the means of entry.
* the cell wall and cuticle layers of plant are the basis for the entry of virus.
* the virus diseases of plants are very rare because infection is not strong enough to kill the plant.
* mostly the virus infection can be recognized by mosaic like leaf pattern, in which loss of chlorophyll leads to yellow in color.
