Plasmid R68.45 was used to construct R' plasmids carrying a maximum of 4 to 5 map minutes of the Pseudomonas aeruginosa PAO chromosome by interspecific mating, using P. putida PPN as the recipient. These R' plasmids were used to determine the map location of the amiE locus and to identify tentatively a number of P. putida auxotrophic mutations. Some of these R' plasmids could not be maintained in recombination-deficient P. aeruginosa strains.
质粒R68.45被用于通过种间交配构建携带最多4至5个基因图谱分钟的铜绿假单胞菌PAO染色体的R'质粒,以恶臭假单胞菌PPN作为受体。这些R'质粒被用于确定amiE基因座的图谱位置,并初步鉴定一些恶臭假单胞菌营养缺陷型突变。其中一些R'质粒无法在重组缺陷型铜绿假单胞菌菌株中维持。
