Editorial: Interplay between NO Signaling, ROS, and the Antioxidant System in Plants

Over the last decades, reactive oxygen and nitrogen species (ROS and RNS), and particularly nitric oxide (NO), have been linked to a wide variety of physiological processes in plants, ranging from the control of developmental processes to the regulation of plant responses against biotic or abiotic stress. In addition to the regulation of ROS and RNS biosynthesis, the exquisite modulation of their activities is also under the control of a complex network of regulatory enzymes and compounds constituting the antioxidant system. The Research Topic on the Interplay between NO signaling, ROS and the antioxidant system in plants aims to provide an up-to-date view of this increasingly important area through both original articles and detailed reviews.
