Plasmid R68.45 was transferred from Pseudomonas aeruginosa PAO25 to the photosynthetic species Rhodopseudomonas gelatinosa and Rhodopseudomonas sphaeroides by selection for resistance to antibiotics. R. sphaeroides strains carrying the plasmid could transfer the plasmid and also chromosomal genes to other strains of R. sphaeroides.
通过选择对抗生素的抗性,将质粒R68.45从铜绿假单胞菌PAO25转移至光合菌种明胶红假单胞菌和球形红假单胞菌。携带该质粒的球形红假单胞菌菌株能够将该质粒以及染色体基因转移至其他球形红假单胞菌菌株。
