Plants are constantly threatened by herbivore attacks and must devise survival strategies. Some plants sense and respond to elicitors including specific molecules secreted by herbivores and molecules that are innate to plants. Elicitors activate diverse arrays of plant defense mechanisms that confer resistance to the predator. Recent new insights into the cellular pathways by which plants sense elicitors and elicit defense responses against herbivores are opening doors to a myriad of agricultural applications. This review focuses on the machinery of herbivory-sensing and on cellular and systemic/airborne signaling via elicitors, exemplified by the model case of interactions between Arabidopsis hosts and moths of the genus Spodoptera.
植物经常受到草食动物的攻击,必须制定生存策略。一些植物能够感知和响应激发子,包括草食动物分泌的特定分子和植物固有的分子。激发子激活了多种植物防御机制,赋予了植物对捕食者的抗性。最近,人们对植物感知激发子和对草食动物产生防御反应的细胞途径有了新的认识,这为农业的诸多应用开辟了道路。本文重点介绍了草食动物感知机制以及通过激发子进行的细胞和系统/空气信号传递,以拟南芥宿主与夜蛾属飞蛾之间的相互作用为例。
