Interpretive Summary:

Technical Abstract: New and emerging pathogens constantly threaten the security of important crops globally. A recently characterized pathogen of rice that was first observed in the United States in 2021, Pantoea ananatis, causes leaf lesions, panicle sterility, and reduced yields to susceptible varieties. To date, repeatable methods to characterize and study symptomology and development of the disease caused by P. ananatis in rice plants are unreliable. This lack of repeatable methodology has hindered the identification of resistant cultivars of rice. Here we report a robust method for inoculating plants with P. ananatis and monitoring symptom development in several rice cultivars commonly grown in the United States. The knowledge gained from this method will provide important information for growers to mitigate the economic impact of this emerging pathogen.
