Abstract

Lambda bacteriophage adsorbs on the chromosome-less small bodies (minicells) produced by aberrant cell division of Escherichia coli P678-54. The plasmid-less minicells, as well as the minicells harbouring the colicinogenic factor E1, reveal a considerable inhibition of total RNA synthesis after phage adsorption. Both kinds of minicells synthesize RNA hybridizable to lambda DNA, but in the plasmid-harbouring minicells lambda RNA synthesis is much more intensive.

摘要

λ噬菌体吸附在大肠杆菌P678 - 54异常细胞分裂产生的无染色体小体(微型细胞)上。无质粒的微型细胞以及携带产大肠杆菌素因子E1的微型细胞,在噬菌体吸附后均显示出总RNA合成受到显著抑制。这两种微型细胞都能合成可与λDNA杂交的RNA,但在携带质粒的微型细胞中,λRNA的合成更为活跃。
