Resistance induction involves the activation of latent defense mechanisms existing in plants in response to treatment with biotic or abiotic agents. The plants have an inducible defense system, in order to save energy. Resistance induced in natural conditions will only cost in the presence of the pathogen. During the evolutionary process, plants acquired a sophisticated defensive strategy to “perceive” the attacks of pathogens and insects, translating this perception into an appropriate and adaptive response. The plant's innate immunity is surprisingly based on the complex response that is highly flexible in its ability to recognize and respond to the most diverse invaders. Thus, detailed knowledge of the molecular mechanisms of induced resistance will be important in the development of biological, durable and environmentally friendly actions for crop protection.

抗性诱导涉及响应于生物或非生物试剂的处理而激活植物中存在的潜在防御机制。植物具有诱导型防御系统，以节省能源。在自然条件下诱导的抗药性只会在存在病原体的情况下产生。在进化过程中，植物获得了一种复杂的防御策略，以“感知”病原体和昆虫的攻击，并将这种感知转化为适当的适应性响应。令人惊讶的是，植物的先天免疫力基于复杂的应答，这种应答在识别和应对最多样化的入侵者的能力上具有高度的灵活性。因此，对诱导抗性分子机制的详细了解对于生物学，
