Plasmid R68.45 classified into the IncP-1 group which is characterized by a broad host range, was transferred from Pseudomonas aeruginosa PA025 or Escherichia coli into Thiobacillus A2 by conjugation. The R plasmid was stably maintained in Thiobacillus A2 but only neomycin/kanamycin resistance was fully expressed in the new host. Conjugational transfer of R68.45 between different Thiobacillus A2 strains was observed. R plasmid mediated transfer of chromosomal markers has been demonstrated.
分类为IncP-1组的质粒R68.45具有广泛的宿主范围，通过接合作用从铜绿假单胞菌PA025或大肠杆菌转移到嗜硫杆菌A2中。R质粒在嗜硫杆菌A2中稳定维持，但只有新霉素/卡那霉素抗性在新宿主中完全表达。观察到R68.45在不同嗜硫杆菌A2菌株之间的接合转移。已证明R质粒介导的染色体标记转移。
