Helicobacter pylori is a genetically diverse bacterial species, owing in part to its natural
competence for DNA uptake that facilitates recombination between strains. Inter‐strain DNA …

Recombination plays a dominant role in the evolution of the bacterial pathogen Helicobacter
pylori, but its dynamics remain incompletely understood. Here we use an in vitro …

Helicobacter pylori are gram-negative bacteria notable for their high level of genetic diversity
and plasticity, features that may play a key role in the organism's ability to colonize the …

For naturally competent microorganisms, such as Helicobacter pylori, the steps that permit
recombination of exogenous DNA are not fully understood. Immediately downstream of an …

Helicobacter pylori, bacteria that colonize the human gastric mucosa, possess a large
number of genes for restriction‐modification (R‐M) systems, and essentially, every strain …

All organisms have pathways that repair the genome, ensuring their survival and that of their
progeny. But these pathways also serve to diversify the genome, causing changes at the …

Background Extensive genetic diversity and rapid allelic diversification are characteristics of
the human gastric pathogen Helicobacter pylori, and are believed to contribute to its ability …

Recombination is a fundamental mechanism for the generation of genetic variation.
Helicobacter pylori strains have different frequencies of intragenomic recombination, arising …

Helicobacter pylori cells are naturally competent for the uptake of both plasmid and
chromosomal DNA. However, we demonstrate that there are strong barriers to …

The generation of a RecA filament on single-stranded DNA is a critical step in homologous
recombination. Two main pathways leading to the formation of the nucleofilament have been …
