Plants perceive the presence of insect eggs deposited on leaves as a cue of imminent herbivore attack. Consequential plant signaling events include the accumulation of salicylic acid and reactive oxygen species, transcriptional reprogramming, and cell death. Interestingly, egg-induced innate immunity shows similarities with immune responses triggered upon recognition of microbial pathogens, and in recent years, it became apparent that egg perception affects plant-microbe interactions. Here, we highlight recent findings on insect egg-induced innate immunity and how egg-mediated signaling impacts plant-microbe interactions. Ecological considerations beg the question: Who benefits from egg perception in these complex interactions?
植物感知到昆虫卵在叶子上的存在，这是即将发生食草动物攻击的信号。随后的植物信号事件包括水杨酸和活性氧的积累、转录重编程和细胞死亡。有趣的是，卵诱导的先天免疫与识别微生物病原体引发的免疫反应相似，近年来，人们明显意识到卵感知会影响植物-微生物相互作用。在这里，我们强调了最近关于昆虫卵诱导的先天免疫的发现，以及卵介导的信号如何影响植物-微生物相互作用。生态考虑因素提出了一个问题：在这些复杂的相互作用中，谁从卵感知中受益？
