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

open access: yeseLife, 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 ...

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

open access: yes, 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.

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

open access: yesMolecular 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.

Persistence and plasticity in bacterial gene regulation [PDF]

open access: yesNature 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 ...

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

open access: yes, 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 ...

Identification of bacterial leaf blight resistance genes in Malaysian local rice varieties [PDF]

open access: yes, 2020
Xanthomonas oryzae pv oryzae (Xoo) is a bacterial pathovar that causes a serious bacterial leaf blight disease of rice. This disease poses significant constraint on food security in Asia, as it causes yield loss in rice.

Patterns of Bacterial Gene Movement [PDF]

open access: yesMolecular 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.

Codon Usage Domains over Bacterial Chromosomes [PDF]

open access: yes, 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 ...

The supragenic organization of glycoside hydrolase encoding genes reveals distinct strategies for carbohydrate utilization in bacteria

open access: yesFrontiers in Microbiology, 2023
Glycoside hydrolases (GHs) are carbohydrate-active enzymes essential for many environmental (e.g., carbon cycling) and biotechnological (e.g., biofuels) processes.

The fate of new bacterial genes [PDF]

open access: yesFEMS Microbiology Reviews, 2009
Bacteria experience a continual influx of novel genetic material from a wide range of sources and yet their genomes remain relatively small. This aspect of bacterial evolution indicates that most newly arriving sequences are rapidly eliminated; however, numerous new genes persist, as evident from the presence of unique genes in almost all bacterial ...
