Abstract

Pseudomonas syringae Pv. syringae is a causal agent of bacterial blossom blight of kiwifruit in Korea. Eleven strains of the pathogen were isolated from different kiwifruit orchards in Korea and the plasmid profiles were obtained by pulsed-field gel electrophoresis. They could be clustered into six groups according to the number and size of plasmids. The number of plasmids per strain and size of these plasmids ranged from 0 to 4 and from 22 to 160 kb, respectively. Among them, four strains belonging to Group III which harbored two plasmids were resistant to copper sulfate. Southern blot hybridization of the plasmid DNA indicated that the copper resistance determinant was carried on a 48 kb plasmid.

Pseudomonas syringae pv. syringae는 우리나라에서 참다래 꽃썩음병의 원인세균으로 알려져 있다. 본 연구에서는 우리나라의 서로 다른 참다래 과수원에서 분리되어 동정된 11개 균주의 꽃썩음병균이 가지고 있는 플라스미드 양상을 pulsed-field 젤 전기영동으로 조사하였다. 그 결과 전체 균주들은 가지고 있는 플라스미드의 개수와 크기에 따라 6개 그룹으로 나누어 졌다. 플라스미드의 수는 0에서 4개, 크기는 22 kb에서 160 kb로 다양하였다. 이들 중 두 개의 플라스미드를 가지고 있는 그를 III에 속하는 4균주가 Cu에 대한 저항성을 보였다. Southern blot hybridization 결과 Cu 저항성 유전자는 48 kb 크기의 플라스미드에 들어 있었다.
