Unraveling the mechanisms of plant disease resistance and immunity is crucial for breeding disease-resistant crops and safeguarding national food security. Photoreceptors, which are central for perceiving environmental signals, not only fine-tune plant growth and development, but also serve as key signaling hubs in plant-pathogen interactions. Studies have demonstrated that photoreceptor interact directly or indirectly with the COP1/SPA complex, HY5, PIFs, and other light-signaling components. By regulating the spatiotemporal expression of resistance-related defense genes and controlling the synthesis and response networks of defense-related hormones, photoreceptors precisely integrate light signals with pattern-triggered immunity (PTI) and effector-triggered immunity (ETI), thereby balancing plant growth and immunity. In recent years, research into the interaction between light signaling and plant immune systems has become a hot topic in the field of plant biology. Elucidating these underlying mechanisms offers new directions for breeding disease-resistant crops. This paper focuses on the molecular mechanisms of plant disease resistance regulated by photoreceptors, particularly the immune activation mechanisms mediated by photoreceptors and their spatiotemporal integration with immune-related hormone signals. Additionally, it delves into the potential application of optogenetic technology in studying this interaction. The aim is to provide new theoretical and technical avenues for future molecular breeding of disease-resistant crops, which will be based on photoreceptor modification and signal transduction pathways.
