RpoN2- and FliA-regulated fliTX is indispensible for flagellar motility and virulence in Xanthomonas oryzae pv. oryzae

BMC Microbiology, 2017
Background Bacterial blight of rice caused by Xanthomonas oryzae pv. oryzae (Xoo) is one of the most important crop diseases in the world. More insights into the mechanistic regulation of bacterial pathogenesis will help us identify novel molecular ...

MTS1338, A Small Mycobacterium tuberculosis RNA, Regulates Transcriptional Shifts Consistent With Bacterial Adaptation for Entering Into Dormancy and Survival Within Host Macrophages

Frontiers in Cellular and Infection Microbiology, 2019
Small non-coding RNAs play a significant role in bacterial adaptation to changing environmental conditions. We investigated the dynamics of expression of MTS1338, a small non-coding RNA of Mycobacterium tuberculosis, in the mouse model in vivo ...

Novel algorithms reveal streptococcal transcriptomes and clues about undefined genes.

PLoS Computational Biology, 2007
Bacteria-host interactions are dynamic processes, and understanding transcriptional responses that directly or indirectly regulate the expression of genes involved in initial infection stages would illuminate the molecular events that result in host ...

Comparative transcriptome and phenotype analysis revealed the role and mechanism of ompR in the virulence of fish pathogenic Aeromonas hydrophila

MicrobiologyOpen, 2020
Aeromonas hydrophila B11 strain was isolated from diseased Anguilla japonica, which had caused severe gill ulcers in farmed eel, causing huge economic losses. EnvZ‐OmpR is a model two‐component system in the bacteria and is widely used in the research of

Temperature-dependent expression of virulence genes in fish pathogenic bacteria

Frontiers in Microbiology, 2015
Virulence gene expression in pathogenic bacteria is modulated by environmental parameters. A key factor in this expression is temperature. Its effect on virulence gene expression in bacteria infecting warm-blooded hosts is well documented.

miRNA expression signatures induced by pasteurella multocida infection in goats lung

Scientific Reports
MicroRNAs (miRNAs) are important regulators of gene expression and are involved in bacterial pathogenesis and host–pathogen interactions. In this study, we investigated the function of miRNAs in the regulation of host responses to Pasteurella multocida ...

Revelation of core promoter elements and bidirectional regulation of Geminivirus genes in Escherichia coli

Virus Research
Several geminiviruses have been show to possess cross-kingdom gene expression capability. In addition, the intergenic region (IR) of geminivirus genomes is known to regulate the transcription of viral early genes (complementary-sense, C-sense) and late ...

The CRISPR-dCas9 interference system suppresses inhA gene expression in Mycobacterium smegmatis

Scientific Reports
CRISPR-dead Cas9 interference (CRISPRi) has become a valuable tool for precise gene regulation. In this study, CRISPRi was designed to target the inhA gene of Mycobacterium smegmatis (Msm), a gene necessary for mycolic acid synthesis.
