In both plants and animals, defense against pathogens relies on a complex surveillance system for signs of danger. Danger signals may originate from the infectious agent or from the host itself. Immunogenic plant host factors can be roughly divided into two categories: molecules which are passively released upon cell damage ('classical' damage-associated molecular patterns, DAMPs), and peptides which are processed and/or secreted upon infection to modulate the immune response (phytocytokines). We highlight the ongoing challenge to understand how plants sense various danger signals and integrate this information to produce an appropriate immune response to diverse challenges.
在植物和动物中，防御病原体依赖于对危险信号的复杂监控系统。危险信号可能来自于感染因子，也可能来自于宿主自身。免疫原性植物宿主因子大致可分为两类：细胞受到损伤时被动释放的分子（“经典”损伤相关分子模式，DAMPs），以及受到感染时被加工和/或分泌以调节免疫反应的肽类（植物细胞因子）。我们强调了目前的挑战，即理解植物如何感知各种危险信号，并整合这些信息，以对各种挑战产生适当的免疫反应。
