摘要

多胺(PAs)是存在于所有活细胞中的小脂肪胺。在植物中，腐胺、亚精胺、精胺和热精胺被称为普遍存在的pa。它们参与各种生理过程和环境应激反应，包括病原体感染。一些研究表明，PAs及其分解代谢产物，如二胺氧化酶和多胺氧化酶产生的h2o2，与宿主防御机制的激活密切相关。本文简要综述了PAs在植物抗病过程中作用的最新进展。

The Role of Polyamines in Plant Disease Resistance

Polyamines (PAs) are small, aliphatic amines that are found in all living cells. In plants, putrescine, spermidine, spermine, and thermospermine are known as ubiquitous PAs. They are involved in various physiological processes and environmental stress responses, including pathogen infections. Several studies have demonstrated that PAs and their catabolic products, such as H 2 O 2 produced by diamine oxidases and polyamine oxidases, are closely involved in the activation of host defense mechanisms. This minireview briefly summarizes recent advances regarding the function of PAs during disease resistance in plants.
