Induced resistance is a plant defense mechanism that enhances a plant's ability to resist pests and diseases after exposure to certain stimuli. This can occur when a plant is attacked by pathogens or insects, prompting it to activate its immune system. The process involves the production of signaling molecules that prepare the plant to respond more effectively to future threats. This phenomenon can also be triggered by beneficial organisms, such as mycorrhizal fungi or bacteria, which help plants recognize potential dangers. Induced resistance is an important aspect of sustainable agriculture, as it reduces the need for chemical pesticides and promotes healthier ecosystems.
