- Turnip yellow mosaic virus (TYMV) is a plant pathogenic virus transmitted mainly through its host Brassica spp. TYMV is originated from Europe. Its infection cases have been reported in Australia, Brazil, Turkey, and Japan. Symptoms similar to those of TYMV infections were also reported in Korea in 2012. In this study, we developed RT-PCR primer pairs that were highly sensitive for detecting TYMV. The developed RT-PCR primer pairs offered about 10–100 times stronger detection sensitivity compared to primer pairs previously used in Korea. As a result, a 491 bp TYMV-specific band was identified. The specific band was confirmed to be TYMV based on sequencing results and phylogenetic analysis. The RT-PCR primer pairs developed in this study can be used to rapidly and precisely diagnose TYMV in agricultural products such as Chinese cabbage and other crops infected by TYMV.
