Development of the differential detection reverse transcription loop-mediated isothermal amplification method for Barley yellow mosaic virus or Japanese soil-borne wheat mosaic virus from barley.

A differential detection reverse transcription loop-mediated isothermal amplification (DD-RT-LAMP) method was developed to detect either Barley yellow mosaic virus (BaYMV) or Japanese soil-borne wheat mosaic virus (JSBWMV) simultaneously. Both primer sets, which recognized either BaYMV or JSBWMV genomic RNA, amplified DNA more efficiently at 65°C using an isothermal DNA amplification and fluorescence detection device. Furthermore, these primer sets showed unique annealing curves.
