Advances in Irradiation Technology for Plant Disease Resistance: A Review

Abstract

Plant diseases pose a significant threat to global food security, leading to substantial yield losses and economic damage. In recent years, irradiation technology has emerged as a promising approach to enhance plant disease resistance. Gamma irradiation, a well-established technique, has been utilized for approximately 60 years to develop new plant varieties with improved resistance to pests and diseases. X-ray is another form of ionizing radiation, has also shown the potential in enhancing plant disease resistance. UV light, including UVB and UVC radiation, has been effective in eliminating microorganisms by damaging their DNA. Electron beam irradiation, a non-ionizing form of radiation, has been investigated for its impact on plant disease resistance. However, the implementation of irradiation technology in agriculture faces challenges such as public perception, regulatory barriers and cost-effectiveness. This review article highlights the advances in irradiation technology for plant disease resistance. It emphasizes the potential of gamma irradiation, X-ray gamma irradiation, UV light, UVB, UVC and electron beam in enhancing plant disease resistance.
