Overall, these results point to a more complex role than is expected for H-NS in modulating genome accessibility and gene expression of recently acquired genes. Bacterial chromatin organization by H-NS protein unravelled using dual DNA manipulation.
For many decades, genomic studies were based on Sanger sequencing or the dideoxy chain termination method of sequencing DNA, along with microarray and hybridization-based techniques to understand genome function. Sanger sequencing was used to sequence the genomes of many organisms, from bacteria to humans.

Southern blot analysis of genomic Tm DNA allowed to produce a partial gene library, which was used as a template for PCRs with gene- and vector-specific primers to identify the complete DNA sequence. As reported for other csp genes, the 5′ untranslated region of the mRNA was anomalously long; it contained the putative Shine–Dalgarno sequence.
Bacterial genomes are rich in horizontally acquired prophages. racR is an essential gene located in the rac prophage that is resident in many Escherichia coli genomes. Employing a clustered regularly interspaced short palindromic repeat CRISPR-Cas-based gene silencing approach, we show that RacR is a negative regulator of the divergently transcribed and adjacent ydaS-ydaT operon in. Large-scale disruption of gene expression states in a Δhns-stpA mutant. a A volcano plot of fold change log 2 scale in expression levels between the Δhns-stpA double mutant and the wild type on the x-axis, and the P-value log 10 scale for the measured fold change on the y-axis.Red dots show genes that are upregulated in the mutant relative to the wild type and green dots represent. Apr 14, 2011 · Transcriptional initiation is arguably the most important control point for gene expression. It is regulated by a combination of factors, including DNA sequence and its three-dimensional topology, proteins and small molecules. In this chapter, we focus on the trans-acting factors of bacterial regulation.
Dec 01, 2017 · Evolve and resequence experiments have provided us a tool to understand bacterial adaptation to antibiotics. In our previous work, we used short-term evolution to isolate mutants resistant to the ribosome targeting antibiotic kanamycin, and reported that Escherichia coli develops low cost resistance to kanamycin via different point mutations in the translation Elongation Factor-G EF-G. The alarmone pppGpp regulates transcription, translation, replication, virulence, lipid synthesis, antibiotic sensitivity, biofilm formation, and other functions in bacteria.

Oct 01, 2018 · Oxidative stress response in bacteria is mediated through coordination between the regulators of oxidant-remediation systems e.g. OxyR, SoxR and nucleoid condensation e.g. Dps, Fis.However, these genetic factors are either absent or rendered non-functional in the human pathogen Mycobacterium tuberculosis Mtb.Therefore, how Mtb organizes genome architecture and regulates gene expression. Nov 13, 2019 · Phagosomal pH and redox heterogeneity in Mycobacterium tuberculosis Mtb can promote tolerance of the bacterium to antibiotics. Mishra et al. found that the approved antimalarial drug chloroquine inhibited this acidification and resulted in altered redox metabolism and improved susceptibility of Mtb to first-line antituberculosis drugs, particularly isoniazid, in infected macrophages.
