Plants are confronted with several biotic stresses such as microbial pathogens and other herbivores. To defend against such attackers, plants possess an array of pattern recognition receptors (PRRs) that sense the danger and consequently initiate a defence programme that prevents further damage and spreading of the pest. Characteristic pathogenic structures, so-called microbe-associated molecular patterns (MAMPs), serve as signals that allow the plant to sense invaders. Additionally, pathogens wound or damage the plant and the resulting release of damage-associated molecular patterns (DAMPs) serves as a warning signal. This review focuses on peptides that serve as triggers or amplifiers of plant defence and thus follow the definition of a MAMP or a DAMP.
植物面临着多种生物胁迫，如微生物病原体和其他食草动物。为了抵御这些攻击者，植物拥有一系列模式识别受体（PRRs），可以感知危险，从而启动防御程序，防止害虫进一步侵害和扩散。特征性的病原结构，即所谓的微生物相关分子模式（MAMPs），作为信号，使植物能够感知入侵者。此外，病原体还会伤害或破坏植物，由此释放的损伤相关分子模式（DAMPs）则作为一种警告信号。本综述重点介绍作为植物防御触发剂或放大器的肽，因此符合 MAMP 或 DAMP 的定义。
