50 Md conjugative plasmid, designated pM3, has been found in the cells from natural isolates of Pseudomonas sp M. The plasmid determines the resistance to tetracycline and streptomycin and is capable of conjugative transfer between the cells of Pseudomonas and Escherichia coli. The conjugative derivatives of pM3 deleted for 14 Md of molecular mass were isolated after acridine dyes treatment of cells harbouring plasmid pM3. The discovered plasmid was not shown to belong to IncP1 incompatibility group.
在假单胞菌属M天然分离株的细胞中发现了一种50 Md的接合质粒，命名为pM3。该质粒决定了对四环素和链霉素的抗性，并且能够在假单胞菌和大肠杆菌的细胞之间进行接合转移。在用吖啶染料处理携带质粒pM3的细胞后，分离出了缺失14 Md分子量的pM3接合衍生物。已发现该质粒不属于IncP1不相容群。
