Popis: To accurately determine the spread of any pathogen, including plant viruses, a quick, sensitive, cost-effective, point-of-care diagnostic assay is necessary. Wheat spindle streak mosaic virus (WSSMV) is a Bymovirus, transmitted by the plasmodiophorid Polymyxa graminis Led, which causes yellow mosaic and reduces the grain yield in wheat. Currently, detection protocols for WSSMV use ELISA or more sensitive PCR-based approaches requiring specialized laboratory and personnel. A protocol for reverse transcription loop mediated isothermal amplification (RT-LAMP) has been developed and optimized for the rapid detection of viruses using crude extracts from wheat leaves. The protocol was specific for WSSMV detection, while no reaction was observed with SBCMV or SBWMV, the non-target viruses transmitted by the same vector. The RT-LAMP assay was shown to be as sensitive as the one-step WSSMV specific RT-PCR. The RT-LAMP assay can be performed under field conditions using a portable instrument, and can help the actual spread of WSSMV, an aspect of this virus not yet well understood, to be explored.
