Description
Summary:In July, 2009, proso millet (Panicum miliaceum), which showing the bacterial brown stripes on leaf sheaths, was collected in Miryang in Korea. Symptoms were systemic brown necrotic stripe lesions on the leaf sheaths and stems, and these symptoms were found in the entire field. The causal agent isolated from symptomatic plants was identified as an Acidovorax avenae subsp. avenae, based on its biochemical and physiological characteristics and also confirmed by the Biolog data and 16S rRNA gene sequence analysis. Also it caused hypersensitive response (HR) when it was inoculated onto the tobacco and tomato. It caused similar symptoms when inoculated onto proso millet. This is the first report of A. avenae subsp. avenae, the causal agent of bacterial brown stripe of the proso millet in Korea. 2009년 7월 밀양지역의 농가포장에서 재배된 기장의 잎에 세균성 줄무늬증상이 발생되었다. 병징은 잎과 줄기전신에서 갈색의 괴저줄무늬를 보였으며, 포장전체에서 확인되었다. 이병된 잎에서 분리된 4계통의 세균들은 배양적, 생리 생화학적 특성, Biolog 검정, 16S rRNA 유전자 염기서열분석에 의하여 Acidovorax avenae subsp. avenae로 동정되었다. 또한 담배, 토마토에 접종하여 과민성반응을 확인하였으며, 기장에 접종하여 동일 병반을 확인할 수 있었다. 이상의 연구결과에 의하여 기장에서 Acidovorax avenae subsp. avenae에 의한 세균성줄무늬병을 국내 처음으로 보고한다.
