Plant viruses are transmitted in a number of ways, the most important of which is through insect bites, primarily by aphids and plant hoppers. One of the most well-studied viruses, tobacco mosaic virus (TMV), is spread mechanically by abrasion with infected sap. Symptoms of virus infection include colour changes, dwarfing, and tissue distortion.
