Abstract

Reactive oxygen species (ROS) is a collective term for highly reactive oxygen derivatives, including singlet oxygen, hydroxyl radicals, superoxide anions, and hydrogen peroxide. In plants, ROS are produced in apoplasts, chloroplasts, mitochondria, and peroxisomes. Although ROS are toxic when their levels exceed a certain threshold, low-concentration ROS can serve as essential signaling molecules for plant growth and development, as well as plant responses to abiotic and biotic stresses. Various aspects of the role of ROS in plants have been discussed in previous reviews. In this review, we first summarize recent progress in the regulatory mechanisms of apoplastic ROS signaling and then propose its potential roles in plant defense against vascular pathogens to provide new ideas for the prevention and control of vascular diseases.

ROS 信号在植物抵御维管病原体中的作用
活性氧(ROS)是高活性氧衍生物的总称,包括单线态氧、羟自由基、超氧阴离子和过氧化氢。在植物中,ROS 在细胞外质、叶绿体、线粒体和过氧物酶体中产生。虽然当 ROS 水平超过一定阈值时会产生毒性,但低浓度的 ROS 可以作为植物生长和发育以及植物对非生物和生物胁迫做出反应的重要信号分子。以前的综述中讨论了 ROS 在植物中作用的各个方面。在这篇综述中,我们首先总结了凋落物 ROS 信号传导调控机制的最新进展,然后提出了它在植物防御维管束病原体中的潜在作用,为预防和控制维管束疾病提供新思路。
