Plants have elaborate and helpful defence mechanisms from viruses. One among the most effective is the existence of so-named resistance (R) genes. Each and every R gene confers resistance to a particular virus by triggering localised parts of cell Dying throughout the contaminated cell, that may typically be noticed While using the unaided eye as massive spots.
