Pairs of normally incompatible derivatives of R100-1 (one ChlS TetR, the other ChilR TetS) were forced to coexist in a recA host by selection for ChlR TetR cells. After many generations stable derivatives were isolated. The analysis of none independent stabilization experiments showed that in each case TetR was translocated from the plasmid to the chromosome of the host. No evidence for the joint integration of other plasmid genes (those controlling transfer, antibiotic resistance, incompatibility, or origin of transfer replication) was obtained. One of the chromosomal TetR determinants was mapped close to metE.
通过筛选ChlR TetR细胞,使R100 - 1的通常不兼容的衍生物对(一个是ChlS TetR,另一个是ChilR TetS)在recA宿主中共存。经过许多代后,分离出了稳定的衍生物。对多个独立的稳定化实验分析表明,在每种情况下,TetR都从质粒转移到了宿主染色体上。未获得其他质粒基因(那些控制转移、抗生素抗性、不相容性或转移复制起点的基因)联合整合的证据。其中一个染色体TetR决定簇被定位在靠近metE的位置。
