| 中文摘要:诱导防御反应的产生取决于植物对植食性昆虫相关信号迅速和准确地识别。在植物与植食性昆虫互作过程中，早期信号事件是负责植物识别和触发下游信号转导途径的最早反应，它们发生在植物防御相关基因表达和防御相关代谢物产生之前，对植物的防御过程至关重要。本文将植物与植食性昆虫互作的早期事件，包括植物对植食性昆虫的感知、电信号和Ca2+信号的产生和转导，活性氧的迸发以及促细胞分裂原活化蛋白激酶（MAPK）信号级联途径等研究进展进行了综述，并提出今后的研究重点与方向，促进对植物诱导防御反应调控网络的研究，以期为改进农业害虫的治理提供重要的理论和技术支撑。 |

| Abstract:The production of defense responses in plants depends on the rapid and accurate recognition of the plant to the herbivore-associated signals. Early signaling events are the initial responses in plantherbivore interactions, which are responsible for plant recognition to the signals and triggering downstream signaling transduction pathways. These events occur before the expression of plant defense-related genes and the production of defensive compounds, and play a vital role in plant defense responses. A summarize was reviewed on the latest advances in early signaling events of plants in response to herbivory, mainly including herbivore-associated signal perception, electrical and calcium signaling, reactive oxygen species (ROS) burst and activation of mitogen-activated protein kinase (MAPK) cascades. Furthermore, the research focus and direction in the future were put forward, and the paper would probably promote the study on the signaling network regulating herbivore-induced plant defenses and thereby provide the theoretical and technological support for improving the control of agricultural insect pest. |
