Plant immobility renders plants constantly susceptible to various abiotic and biotic stresses. Abiotic and biotic stresses are known to produce reactive oxygen species (ROS), which cause comparable cellular secondary reactions (osmotic or oxidative stress), leading to agricultural productivity constraints worldwide. To mitigate the challenges caused by these stresses, plants have evolved a variety of adaptive strategies. Phenolic acids form a key component of these strategies, as they are predominantly known to be secreted by plants in response to abiotic or biotic stresses. Phenolic acids can be divided into different subclasses based on their chemical structures, such as hydroxybenzoic acids and hydroxycinnamic acids. This review analyzes hydroxycinnamic acids and their derivatives as they increase under stressful conditions, so to withstand environmental stresses they regulate physiological processes through acting as signaling molecules that regulate gene expression and biochemical pathways. The mechanism of action used by hydroxycinnamic acid involves minimization of oxidative damage to maintain cellular homeostasis and protect vital cellular components from harm. The purpose of this review is to highlight the potential of hydroxycinnamic acid metabolites/derivatives as potential antioxidants. We review the uses of different secondary metabolites associated with hydroxycinnamic acid and their contributions to plant growth and development.

深入了解羟基肉桂酸及其次生代谢物作为抗氧化剂对环境胁迫下氧化应激和植物生长的影响。

植物的固定性使植物经常受到各种非生物和生物胁迫的影响。众所周知，非生物和生物胁迫会产生活性氧（ROS），从而引起类似的细胞次级反应（渗透或氧化胁迫），导致全球农业生产力受到限制。为了减轻这些压力带来的挑战，植物进化出了多种适应策略。酚酸是这些策略的关键组成部分，因为已知它们主要是由植物响应非生物或生物胁迫而分泌的。酚酸根据其化学结构可分为不同的亚类，例如羟基苯甲酸和羟基肉桂酸。这篇综述分析了羟基肉桂酸及其衍生物在压力条件下增加的情况，因此为了承受环境压力，它们通过充当调节基因表达和生化途径的信号分子来调节生理过程。羟基肉桂酸的作用机制涉及最大限度地减少氧化损伤，以维持细胞稳态并保护重要的细胞成分免受伤害。本综述的目的是强调羟基肉桂酸代谢物/衍生物作为潜在抗氧化剂的潜力。我们回顾了与羟基肉桂酸相关的不同次生代谢物的用途及其对植物生长和发育的贡献。
