Development of rapid and highly sensitive detection of Bean common mosaic necrosis virus in leguminous crops using loop-mediated isothermal amplification assay

초록

Bean common mosaic necrosis virus (BCMNV) is a plant pathogenic virus that can infect leguminous crops such as kidney beans, sunn hemp, red beans, and mung beans. BCMNV has not been reported in Korea and is classified as a quarantine plant virus. Currently, the standard diagnostic method for diagnosis of BCMNV is reverse transcription (RT)-nested PCR system. However a more rapid monitoring system is needed to enable the testing of more samples. The use of highly efficient loop-mediated isothermal amplification (LAMP) assay for its detection has not yet been reported, and development of LAMP for detecting BCMNV in this study. In addition, confirmation of LAMP amplification can be achieved using restriction enzyme Mse I (T/TAA). The developed technique could be used for more rapid, specific and sensitive monitoring of BCMNV in leguminous crops than conventional nested RT-PCR.
