The genome structure—how genes are organized within DNA sequences in an organism—is fundamental to the processes and functions of organisms. A team at the University of Tokyo has developed a system to ...

A 2026 study in two insect-pathogenic bacterial genera found that selection, genetic drift and biased recombination jointly ...

Bacteria and the viruses that infect them—known as phages—coexist in soils, oceans and living organisms. Scientists have long ...

Bacteria are the most diverse organisms on Earth, with a number of species that’s difficult to quantify. They’re also incredibly old. Bacteria consist of a single cell. They do not have bones and are ...

A mathematical model predicts that competition among mobile genetic elements can lead to low-cost host-benefiting defenses or ...

Some bacteria evolve like clockwork with the seasons, researchers report. The researchers found that through the course of a year, most individual species of bacteria in Wisconsin’s Lake Mendota ...

Unlike most bacteria, Caulobacterales bacteria divide asymmetrically when they reproduce, which creates two cells that look different from each other (top part of the illustration). However, the ...

Lines of bacterial genome sequences are made to evolve independently by introducing high-activity insertion sequences, each simulating decades of evolution in the wild in just weeks. The genome ...

The first-of-its-kind in-depth bacterial evolutionary map could pave the way for the development of precision treatments for certain antibiotic-resistant infections, such as urinary tract infections.

The genetic culprits responsible for the spread of multidrug resistance (MDR) in bacteria have been identified by new research mapping 100 years of bacterial evolution. Experts at the Wellcome Sanger ...
