The landscape of coadaptation in Vibrio parahaemolyticus

eLife, 2020
Investigating fitness interactions in natural populations remains a considerable challenge. We take advantage of the unique population structure of Vibrio parahaemolyticus, a bacterial pathogen of humans and shrimp, to perform a genome-wide screen for ...

The nucleotide composition of microbial genomes indicates differential patterns of selection on core and accessory genomes [PDF]

BMC Genomics, 2017
The core genome consists of genes shared by the vast majority of a species and is therefore assumed to have been subjected to substantially stronger purifying selection than the more mobile elements of the genome, also known as the accessory genome.

Pan-Genome of Novel Pantoea stewartii subsp. indologenes Reveals Genes Involved in Onion Pathogenicity and Evidence of Lateral Gene Transfer

Microorganisms, 2021
Pantoea stewartii subsp. indologenes (Psi) is a causative agent of leafspot on foxtail millet and pearl millet; however, novel strains were recently identified that are pathogenic on onions. Our recent host range evaluation study identified two pathovars;

Evolution of the accessory genome

The accessory genome, the set of genes variably present across members of a bacterial species, plays a central role in shaping microbial diversity and adaptation. Instead of a random collection of mobile elements, evidence has shown that the accessory genome is structured by selective forces, particularly negative frequency-dependent selection, and ...

Comparative genome analysis of the genus Shewanella unravels the association of key genetic traits with known and potential pathogenic lineages

Frontiers in Microbiology, 2023
Shewanella spp. are Gram-negative rods widely disseminated in aquatic niches that can also be found in human-associated environments. In recent years, reports of infections caused by these bacteria have increased significantly.

The genome of Rhizobium leguminosarum has recognizable core and accessory components [PDF]

Genome Biology, 2006
Abstract Background Rhizobium leguminosarum is an α-proteobacterial N2-fixing symbiont of legumes that has been the subject of more than a thousand publications. Genes for the symbiotic interaction with plants are well studied, but the adaptations that allow survival and growth in the soil environment are

Phylogenomics of Globally Spread Clonal Groups 14 and 15 of Klebsiella pneumoniae

Microbiology Spectrum, 2023
Klebsiella pneumoniae sequence type 14 (ST14) and ST15 caused outbreaks of CTX-M-15 and/or carbapenemase producers worldwide, but their phylogeny and global dynamics remain unclear. We clarified the evolution of K.

Whole-genome and pan-genome analyses reveal genomic differences among nontypeable Haemophilus influenzae isolates from bronchiectasis, community-acquired pneumonia, and chronic obstructive pulmonary disease

Frontiers in Cellular and Infection Microbiology
BackgroundNontypeable Haemophilus influenzae (NTHi) is a major bacterial pathogen in both acute and chronic respiratory diseases, yet the genomic basis underlying its association with different clinical phenotypes remains incompletely understood ...

Defence systems drive accessory genome interactions in Pseudomonas aeruginosa

ISME Communications
Abstract Bacterial genomes represent dynamic ecological systems in which highly dynamic accessory genome element compositions drive evolution. Emerging evidence suggests that bacterial defence systems, which protect against phages and other genetic elements, can interact cooperatively, competitively, and antagonistically to influence ...
