| 摘 要： | 通过对浙江宁海县疑似甘薯茎腐病等检疫性病害的调查,在甘薯病株上分离纯化获得能够引起烟草过敏反应的4株分离物,通过菌落形态观察、革兰氏染色反应、16S rRNA序列分析以及致病性测定等细菌学测定,将这4株菌株都鉴定为西瓜噬酸菌(Acidovorax citrulli,原Acidovorax avenae subsp. citrulli),序列同源性高达99.00%~100.00%。瓜类细菌性果斑病菌为我国的检疫性有害生物,务必引起高度重视,以保障浙江重要经济作物西甜瓜产业的健康发展。 |

| Abstract: | Bacterial stem and root rot of sweet potato is an important quarantine disease. In the current study, four isolates of suspected diseased sweet potato induced a hypersensitive response on tobacco plants. These isolates were then identified into Acidovorax citrulli (formerly Acidovorax avenae subsp. citrulli) based on morphology, Gram's stain reaction, 16S rRNA sequence and pathogenicity analysis. Results here showed that the sequence homology of the novel isolates was as high as 99.00%-100.00% compared with A. citrulli, the bacterial pathogen of bacterial fruit blotch of cucurbits, which was the key quarantine pathogen of China. The current report indicated the importance of disease management for efficient controlling of bacterial fruit blotch of watermelon in Zhejiang Province. |
