Special Issue Information

Dear Colleagues,

Reactive oxygen species (ROS) play pivotal roles as signaling molecules in plants, balancing growth and stress responses. This Special Issue focuses on the intricate interplay between ROS-mediated signaling pathways and the trade-offs plants face between development and defense. By shedding light on how ROS influence key cellular processes, we aim to uncover their dual role as signaling mediators and drivers of oxidative damage.

A central theme is the critical function of the antioxidant defense system in maintaining ROS homeostasis, ensuring proper signaling while mitigating oxidative stress. This issue aims to bring together multidisciplinary perspectives, integrating biochemical, molecular, and evolutionary approaches to explore ROS-driven mechanisms.

We welcome original research and reviews that delve into ROS regulation, the signal transduction networks, crosstalk with phytohormones, and the evolutionary adaptations of plants to modulate ROS dynamics under diverse environmental conditions. Contributions highlighting the impact of ROS on crop resilience and biotechnological applications are also encouraged.

This collection aims to advance our understanding of ROS as central players in plant biology and to inspire innovative strategies for sustainable agriculture.

Reactive oxygen species (ROS), as redox messengers, play an important role in regulating plant growth, sensing biotic and abiotic stresses, and integrating different environmental signals. As the microenvironment of the interaction between root, soil and microorganism, the rhizosphere is the hotspot of ROS production and action. Root exudates are an important medium for communication between roots and the soil environment, and they have a significant regulatory effect on the production of ROS in the rhizosphere. At the same time, the formation of rhizosphere ROS is determined by the coupling of various biotic and abiotic factors, and it is also affected by environmental stresses such as temperature, humidity, and disease. This review summarizes how root exudates affect plant growth and induce plant defense mechanisms by regulating the generation and distribution of ROS. It also discusses the role of ROS in promoting the decomposition of soil organic matter, nutrient cycling, and pollutant degradation and transformation. In-depth study of the regulation mechanism of root exudates on ROS not only helps to reveal the molecular mechanism of plant adaptation to environmental stress but also provides theoretical support and practical guidance for sustainable agricultural development and ecological environment protection.
