plant disease resistance

Plant disease resistance is the plant's ability to defend itself against harmful organisms like bacteria, fungi, and viruses. It involves recognizing the invading pathogen through specific genes and activating defense responses, such as producing protective chemicals or strengthening cell walls. This natural or bred trait helps plants survive and produce food despite threats from diseases. Some plants have built-in resistance genes, and scientists work to identify and incorporate these into crops to improve their durability and yield without relying solely on pesticides.
