Genetic tests are highly sensitive, and quantitative methods for diagnosing human viral infections, including COVID-19, are also being used to diagnose plant diseases in various agricultural settings. Conventional genetic tests for plant viruses are mostly based on methods that require purification and amplification of viral genomes from plant samples, which generally take several hours in total, making it difficult to use them in rapid detection at point-of-care testing (POCT). In this study, we developed Direct-SATORI, a rapid and robust genetic test that eliminates the purification and amplification processes of viral genomes by extending the recently developed amplification-free digital RNA detection platform called SATORI, allowing the detection of various plant viral genes in a total of less than 15 min with a limit of detection (LoD) of 98 ∼ copies/μL using tomato viruses as an example. In addition, the platform can simultaneously detect eight plant viruses directly from ∼1 mg of tomato leaves with a sensitivity of 96% and a specificity of 99%. Direct-SATORI can be applied to various infections related to RNA viruses, and its practical use is highly anticipated as a versatil
