In plants, radiation hormesis phenomenon occurs as enhanced growth, accelerated development, increased tolerance to stressors, or accumulation of compounds of interest in response to low-dose irradiation. This review summarizes the recent findings regarding radiation hormesis in plants in response to ionising or UV-radiation. While molecular mechanisms of UV-hormesis are clearer and involve sensing of UV-radiation by the specific photoreceptors, the precise molecular events underlying hormetic responses to ionising radiation are yet to be uncovered. Based on the available information, the scheme of possible pathways triggering radiation stimulation response in cells is discussed. It is argued that beneficial responses to low-dose ionising radiation may depend on the optimization of hydrogen peroxide (H2O2) levels and the interplay between the signalling pathways of reactive oxygen species (ROS) and phytohormones.
期刊介绍：
The aims and scope of Current Opinion in Toxicology is to systematically provide the reader with timely and provocative views and opinions of the highest qualified and recognized experts on current advances in selected topics within the field of toxicology. The goal is that Current Opinion in Toxicology will be an invaluable source of information and perspective for researchers, teachers, managers and administrators, policy makers and students. Division of the subject into sections: For this purpose, the scope of Toxicology is divided into six selected high impact themed sections, each of which is reviewed once a year: Mechanistic Toxicology, Metabolic Toxicology, Risk assessment in Toxicology, Genomic Toxicology, Systems Toxicology, Translational Toxicology.
