Schematic model for the role of MORF genes in plant immunity. The MORF-regulated ROS burst is likely achieved through its effect on the functionality of Photosystem I and II. Upstream transcription factors regulate the expression of MORF genes. MORF genes participate in the RNA editing of chloroplast photosystem genes and subsequently affect the cyclic electron flow activities. Stress such as pathogen infection and UVB irradiation leads to the down-regulation of MORF genes and reduced RNA editing efficiency, thereby impairing CEF, and up-regulating ROS levels, Calcium influx, which enhances the immunity to stress
