| 摘 要： | 采用聚合酶链反应（ＰＣＲ）扩增了椰毒假单胞菌代表菌株Ｔ７７０７的部分１６ＳｒＲＮＡ基因片段，将扩增片段克隆到Ｍ１３ｍｐ１９噬菌体，扩增后提取其单链ＤＮＡ，用ＤＮＡ测序仪进行测序。所得结果与已发表的其它已知假单胞菌的相应序列进行比较，计算出各菌之间的差异，并据此进行聚类。结果表明椰毒假单胞菌在系统发育上与Ｂｕｒｋｈｏｌｄｅｒｉａ属的成员关系密切，而与其它假单胞菌种的关系很远。这表明，椰毒假单胞菌应为Ｂｕｒｋｈｏｌｄｅｒｉａ属的一个种。 |

| Abstract: | Based on the study of its phenotypic characterization and DNA-DNA homology with other Pseudomonas ,the partial 16S rRNA of Pseudomonas cocovenenas was amplified by polymerase chain reaction and sequenced in DNA sequenter after the amplified gene segment was cloncd into bacteriophage M13mp19. The result was compared with those of relative bacteria that had been published. The distance was calculated and phylogenetic tree was drawn based on sequence data. With the consideration of its phenotype and the result in the research,we believe that,P. cocovenenans could belong to genus Burkholderia. |
