RNA phage production was observed in Escherichia coli hfq mutant strains transformed with plasmids containing genomic cDNA of phages Qbeta or MS2. Qbeta production was reduced 5000-fold in an insertional mutant containing an omega cassette in the middle of hfq, but was unaffected in a mutant with the cassette near the end of hfq. The insertions had no effect on MS2 replication.
在用含有噬菌体Qβ或MS2基因组cDNA的质粒转化的大肠杆菌hfq突变菌株中观察到RNA噬菌体的产生。在hfq中间含有一个ω盒的插入突变体中,Qβ的产生减少了5000倍,但在盒靠近hfq末端的突变体中不受影响。这些插入对MS2复制没有影响。
