Reactive oxygen species (ROS) are highly toxic molecules generated during photosynthesis and aerobic respiration. However, ROS are enzymatically produced in a highly regulated manner spatially and temporally. ROS play key roles in regulating a broad range of physiological processes, such as growth and development, defense responses against biotic and abiotic stresses. The ROS-producing enzyme, Nox/Rbohs, act as key signaling nodes integrating multiple signal transduction pathways in plants. Based on these critical positive and negative roles of ROS in plants, treatment with external ROS and other reactive/intermediate species by various technology including plasma could modulate the growth and quality of crops. Interdisciplinary intimate collaboration between plant physiology and engineering would open the door to developing the next generation of agriculture.
