Ionizing radiation causes water radiolysis,which generates highly reactive hydroxyl radicals. The overproduction of reactive oxygen species(ROS)in plants cause damage to proteins,lipids,carbohydrates and DNA,which ultimately results in oxidative stress. To protect themselves against these toxic oxygen intermediates,
