The recognition of insect and pathogen attack requires the plant's ability to perceive chemical cues generated by the attacker. In contrast to the recognition of microbe-associated molecular patterns and effectors, little is known about the molecular recognition of herbivore-associated elicitors (HAEs) and the signaling mechanisms operating in plants after their perception. HAE perception depends strongly on the natural history of both plants and insects and it is therefore expected that many of the responses induced by different HAEs are specific to the species involved in the interaction. The interaction between Nicotiana attenuata and the specialist lepidopteran Manduca sexta presents a relevant biological system to understand HAE perception and signal transduction systems in plants.
昆虫和病原体攻击的识别需要植物能够感知攻击者产生的化学线索。与微生物相关的分子模式和效应子的识别不同，人们对食草动物相关激发子（HAEs）的分子识别以及它们被感知后在植物中起作用的信号机制知之甚少。HAE 的感知强烈依赖于植物和昆虫的自然历史，因此可以预期，不同 HAE 诱导的许多反应都特定于参与相互作用的物种。Nicotiana attenuata 和专性鳞翅目昆虫 Manduca sexta 之间的相互作用为理解植物中 HAE 感知和信号转导系统提供了一个相关的生物学系统。
