这种现象称为质粒的不相容性(incompatibility)。 一般来说,同种质粒衍生物是不相容的,而不同质粒的衍生物则可能是相容性的,也可能是不相容性的。 质粒的不相容性也是与质粒复制起始的控制密切相关的。由于性状相近的质粒通常具有相同或相似的复制调控机制,其阻遏物(抑制物或重复序列)亦相似,在调控时,它们也能...

We found that the clusters “inc” (incompatibility group) and “rep_cluster” (uncharacterized types) were the dominant groups in the gut plasmidome (Fig. 1a) and were significantly phylogenetically different from each other (phylogenetic signal, Pagel’s λ: 0.93; p-value (based on LR test...

These two plasmids are distant from all known IncP families and have not been assigned to any incompatibility group. In the present study we report the complete nucleotide sequence of the self-transmissible TOL plasmid pD2RT of Pseudomonas migulae strain D2RT isolated from Baltic Sea water. ...
Results Discovery of a novel ILE During an investigation of plasmid-encoded copper resist- ance in environmental pseudomonads recovered in a pre- vious study (Pickup, 1989), we attempted to cure native plasmids from these strains by incompatibility using the IncP-9 toluene...
