摘要
对采自浙江东阳市的玉米细菌性叶斑病标样进行分离和鉴定。结果表明,菌株YB125-2、YB125-3和YB184具有致病性。对这3个菌株进行培养、形态特征鉴别、常规生理生化性状测定、全细胞脂肪酸分析和16S rDNA序列分析的多种鉴定,鉴定为巨大芽孢杆菌Bacillus megaterium。巨大芽孢杆菌能够侵染玉米并引起叶斑病。
Some bacterial strains which isolated from diseased leaves of maize in Dongyang county of Zhejiang province, were identified as causal agent of bacterial leaf spot. Based on cultural and morphological characters, physiological and biochemical properties, whole-cell fatty acid and 16S rDNA sequence analysis, strains, YB125-2, YB125-3 and YB184, were identified as species Bacillus megaterium. Bacillus megaterium could infect maize and causing leaf spot.
