Occurrence of Three Major Soybean Viruses, Soybean mosaic virus, Soybean yellow mottle mosaic virus and Soybean yellow common mosaic virus Revealed by a Nationwide Survey of Subsistence Farming Soybean Fields

| Summary: | Soybean yellow mottle mosaic virus (SYMMV) and Soybean yellow common mosaic virus (SYCMV) were
recently isolated in Korea, and it has not been reported how two viruses were dispersed in Korea. In 2012, we
performed nationwide survey in subsistence soybean farming. Suspicious virus-infected infected leave were
collected from the field and a total of 682 soybean tissue samples were assayed by RT-PCR using triplex
primers detecting SYMMV, SYCMV, and Soybean mosaic virus (SMV). On hundred two samples showed
SMV positive, and SYMMV and SYCMV were detected in 116 and 17 tissue samples, respectively. No sample
showed double infection of SYMMV and SYCMV, but there were double infection tissues indicating two
viruses positive of SMV plus SYMMV (5 tissue samples) and SMV plus SYCMV (1 tissue sample). Through
this first subsistence soybean farming field survey, we assumed soybean viruses were originated from home
seed production managed by farmer. Thus, in order to prevent possible seed transmission and further
damage caused by virus transmission, virus-free commercial soybean seeds are recommended to be planted. |
