About

Over the last decades, nitric oxide (NO) has emerged as an essential player in redox signalling. Reactive oxygen species (ROS) also act as signals throughout all stages of plant life. Because they are potentially harmful for cellular integrity, ROS and NO levels must be tightly controlled, especially by the classical antioxidant system and additional redox-active metabolites and proteins. Recent work provided evidence that NO and ROS influence each other’s biosynthesis and removal. Moreover, novel signalling molecules resulting from the chemical reaction between NO, ROS and plant metabolites have been highlighted, including N2O3, ONOO-, NO2, S-nitrosoglutathione and 8-NO2cGMP. They are involved in diverse plant physiological processes, the best characterized being stomata regulation and stress defense.

Taken together, these new data demonstrate the complex interactions between NO, ROS signalling and the antioxidant system, although complementary investigations are needed to provide a global comprehension of this system.

Therefore this Frontiers in Plant Science Research Topic aims to address the following major issues related to the interplay between NO signalling, ROS and the antioxidant system in plants:

o Common targets and receptors (e.g. NPR1, N-end rule pathway) - how is the specificity of signalling conferred?
o Interaction of NO and ROS signalling with redox-active proteins such as thioredoxins, peroxiredoxins, hemoglobins, etc.
o Identification of new NO- and ROS-derived redox signals
o Detailed description of redox signal cascades and networks
o Regulation of ROS homeostasis by NO and vice versa
o Regulation of antioxidant enzymes by NO
o Interaction with plant hormones o Interaction with H2S
o Physiological processes regulated by NO and ROS
o Stomata regulation, root growth, cellulose biosynthesis
o Plant defence responses o Programmed cell death
o Systemic acquired resistance, systemic wound response, systemic acquired acclimation

We welcome research papers, reviews and opinion papers. All contributions will be subject to the innovative peer review process established by Frontiers in Plant Science.
