rRNA transcription rate in Escherichia coli.
نویسندگان
چکیده
The rate of in vivo transcription elongation for Escherichia coli rRNA operons was determined by electron microscopy following addition of rifampin to log-phase cultures. Direct observation of RNA polymerase positions along rRNA operons 30, 40, and 70 s after inhibition of transcription initiation yielded a transcription elongation rate of 42 nucleotides per s.

Detection of Viable But Non-Culturable State of Escherichia coli O157:H7 Using Reverse Transcription PCR
Background and Aims: Many bacteria including Escherichia coli may enter into a viable but non-culturable (VBNC) state under unfavorable stresses, which are unable to be detected by culture-based methods. In this study, the use of Reverse Transcription PCR (RT-PCR) for detection of VBNC state of E. coli O157:H7 was investigated. Materials and Methods: Escherichia. coli O157:H7 was inoculated i...
متن کاملControl of rRNA transcription in Escherichia coli.
The control of rRNA synthesis in response to both extra- and intracellular signals has been a subject of interest to microbial physiologists for nearly four decades, beginning with the observations that Salmonella typhimurium cells grown on rich medium are larger and contain more RNA than those grown on poor medium. This was followed shortly by the discovery of the stringent response in Escheri...
متن کاملDevelopment of 16S rRNA targeted PCR methods for the detection of Escherichia coli in Rainbow trout (Oncorhynchus mykiss)
Objectives: The presence of E.coli in fish intended for human consumption may constitute a potential danger, not only in causing disease, but also because of the possible transfer of antibiotic resistance from aquatic bacteria to those infecting humans. The objective of this study was to develop an improved PCR method based on species – specific 16 S rRNA gene primers (FES,...
متن کاملDetection of yeast ribosomal RNA sequences in E. coli infected with hybrid bacteriophage.
Yeast ribosomal DNA was inserted into Escherichia coli on a bacteriophage vector and the host cell RNA was then extracted and analyzed for the presence of yeast ribosomal RNA sequences. RNA complementary to yeast rDNA was detected by hybridization. The transcription of yeast rDNA was found to be independent of phage RNA synthesis and to occur on the same DNA strand as rRNA transcription in yeas...
متن کاملPhysiological and genetic regulation of rRNA synthesis in Lactococcus.
The macromolecular composition of Lactococcus was regulated by growth rate in the same general way as that of less fastidious bacteria such as Escherichia coli and Salmonella typhimurium. The ratios of RNA:DNA and RNA:protein increased approximately threefold over a 13.5-fold increase in growth rate, whereas the ratio of DNA:protein remained approximately constant. Using reporter genes fused to...
