参与羟基肉桂酸酰胺（HCAA）途径的化合物是植物中一类重要的代谢产物。大量研究表明，多种植物羟基肉桂酰胺在植物与病原体相互作用中发挥着关键作用，例如对香豆酰胍基丁和阿魏酸。本文综述了近年来羟基肉桂酸酰胺（HCAAs）积累与植物抗病性的关系、HCAAs的抗菌活性以及HCAAs参与植物免疫反应（如活性氧、细胞壁反应、植物防御激素和气孔免疫）的机制等方面的研究进展。然而，这些进展也揭示了HCAAs参与植物防御反应的复杂性，还有许多谜团有待揭示。这篇综述概述了迄今为止获得的机制和概念性见解，并强调了未来探索植物化学防御代谢物的领域。
The compounds involved in the hydroxycinnamic acid amide (HCAA) pathway are an important class of metabolites in plants. Extensive studies have reported that a variety of plant hydroxycinnamamides exhibit pivotal roles in plant–pathogen interactions, such as p-coumaroylagmatine and ferulic acid. The aim of this review is to discuss the emerging findings on the functions of hydroxycinnamic acid amides (HCAAs) accumulation associated with plant defenses against plant pathologies, antimicrobial activity of HCAAs, and the mechanism of HCAAs involved in plant immune responses (such as reactive oxygen species (ROS), cell wall response, plant defense hormones, and stomatal immunity). However, these advances have also revealed the complexity of HCAAs participation in plant defense reactions, and many mysteries remain to be revealed. This review provides an overview of the mechanistic and conceptual insights obtained so far and highlights areas for future exploration of phytochemical defense metabolites.
