Aqueous Chlorine Dioxide Treatment to Activate Plant Immunity by Inducing Programmed Cell Death (PCD) and PR (Pathogenesis-related) Genes

Reactive oxygen species (ROS; containing superoxide, hydroxyl, hydrogen peroxide, oxides of nitrogen, and so on) are related to various plant physiological reaction like cell signaling and stress resistance reaction. Our goal is to trigger plant immunity by inducing ROS with chlorine dioxide (ClO2), which known as strong oxidant. Two plants (Arabidopsis (Arabidopsis thaliana) Columbia-0 (Col-0) and Pepper (Capsicum annuum)) were used to identify the relationship between ClO2 treatment and PCD, PR protein and ROS related genes to pathogen.
