Bacterial autolysins trim cell surface peptidoglycan to prevent detection by the Drosophila innate immune system

eLife, 2014
Bacteria have to avoid recognition by the host immune system in order to establish a successful infection. Peptidoglycan, the principal constituent of virtually all bacterial surfaces, is a specific molecular signature recognized by dedicated host ...

Genome-wide identification of bacterial plant colonization genes. [PDF]

PLoS Biology, 2017
Diverse soil-resident bacteria can contribute to plant growth and health, but the molecular mechanisms enabling them to effectively colonize their plant hosts remain poorly understood. We used randomly barcoded transposon mutagenesis sequencing (RB-TnSeq)

The emergence and fate of horizontally acquired genes in Escherichia coli [PDF]

, 2008
Bacterial species, and even strains within species, can vary greatly in their gene contents and metabolic capabilities. We examine the evolution of this diversity by assessing the distribution and ancestry of each gene in 13 sequenced isolates of ...

Transcriptional adaptation of shigella flexneri during infection of macrophages and epithelial cells : insights into the strategies of a cytosolic bacterial pathogen [PDF]

, 2004
Shigella flexneri, the etiologic agent of bacillary dysentery, invades epithelial cells as well as macrophages and dendritic cells and escapes into the cytosol soon after invasion.

Xv4-vrxv4: A New Gene-for-Gene Interaction Identified Between Xanthomonas campestris pv. Vesicatoria Race T3 and the Wild Tomato Relative Lycopersicon pennellii

Molecular Plant-Microbe Interactions, 2000
Strains of tomato race 3 (T3) of Xanthomonas campestris pv. vesicatoria elicit a hypersensitive response (HR) in leaves of Lycopersicon pennellii LA716.

The coevolution of toxin and antitoxin genes drives the dynamics of bacterial addiction complexes and intragenomic conflict [PDF]

, 2012
Bacterial genomes commonly contain 'addiction' gene complexes that code for both a toxin and a corresponding antitoxin. As long as both genes are expressed, cells carrying the complex can remain healthy.

Persistence and plasticity in bacterial gene regulation [PDF]

Nature Methods, 2021
Organisms orchestrate cellular functions through transcription factor (TF) interactions with their target genes, although these regulatory relationships are largely unknown in most species. Here we report a high-throughput approach for characterizing TF-target gene interactions across species and its application to 354 TFs across 48 bacteria ...

Codon Usage Domains over Bacterial Chromosomes [PDF]

, 2006
The geography of codon bias distributions over prokaryotic genomes and its impact upon chromosomal organization are analyzed. To this aim, we introduce a clustering method based on information theory, specifically designed to cluster genes according to ...

Patterns of Bacterial Gene Movement [PDF]

Molecular Biology and Evolution, 2004
Lateral gene transfer has emerged as an important force in bacterial evolution. A substantial number of genes can be inserted into or deleted from genomes through the process of lateral transfer. In this study, we looked for atypical occurrence of genes among related organisms to detect laterally transferred genes.

Development and application of the active surveillance of pathogens microarray to monitor bacterial gene flux. [PDF]

, 2008
BACKGROUND: Human and animal health is constantly under threat by emerging pathogens that have recently acquired genetic determinants that enhance their survival, transmissibility and virulence.
