Summary: | In 2015, a nationwide survey was carried out to investigate about occurrence pattern of virus infecting foxtail millet. A total 100 foxtail millet leaf samples showing virus-like and abnormal symptoms were collected in the seven main cultivated regions of Korea. Four viruses were identified using reverse transcription polymerase chain reaction and RNA sequencing. Of the collected 100 foxtail millet samples, 10 were Barley virus G (BVG), 4 were Rice stripe virus (RSV), 1 was Northern cereal mosaic virus (NCMV), and 1 was Sugarcane yellow leaf virus (ScYLV) infection. To our best knowledge, this is the first report of BVG and NCMV infecting foxtail millet in Korea and ScYLV is expected as new Polerovirus species. This research will be useful in breeding for improved disease-resistant foxtail millet cultivars. 2015년, 조 바이러스 발생양상을 구명하기 위하여 전국적인 조사를 실시하였다. 주요재배단지 7개 지역에서 이상 증상과 바이러스 병징을 보이는 식물체 100점을 수집하여, RT-PCR 진단과 RNA sequencing 방법을 이용하여 전체 4종의 바이러스를 동정하였다. 수집한 시료에서는 Barley virus G (BVG)가 10점, Rice stripe virus (RSV)는 4점, Northern cereal mosaic virus (NCMV), Sugarcane yellow leaf virus (ScYLV)가 각각 1점씩 검출되었다. 이들중에서 BVG와 NCMV는 국내 조에서 첫 발생보고이며, ScYLV는 Polerovirus속의 신종으로 예상된다. 본 연구결과는 조 식물체의 무병종자와 저항성 품종개발을 위한 기초연구 자료로 이용 가능할 것으로 생각된다. |
