What are the various modes of infection and dissemination of plant diseases caused by viruses ? Describe.
Plant viruses, being obligate intracellular parasites, cannot actively penetrate plant tissues on their own due to the rigid cell wall. Therefore, they rely on various external agents for infection. The primary modes of infection include:
Once a plant is infected, the virus needs to disseminate to new hosts and areas. The modes of dissemination largely overlap with the infection methods, but on a broader scale:
Understanding these mechanisms is crucial for developing effective disease management strategies.
