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.
