Natural Plant Defenses

Natural plant defenses refer to the innate mechanisms plants use to defend against pests, diseases, and environmental stressors. These defenses can be physical, such as thick leaves or spiny structures, or chemical, such as the production of toxins or repellents. Plants also produce secondary metabolites like alkaloids and terpenes, which act as deterrents to herbivores and pathogens. Additionally, plants can employ mutualistic relationships with beneficial organisms, such as nitrogen-fixing bacteria or predator insects, to enhance their resilience. By selecting and breeding crops with strong natural defenses, farmers can reduce reliance on chemical pesticides and foster more sustainable farming systems.
