Viruses of bacteria (bacteriophages or phage) have broad effects on bacterial ecology and
evolution in nature that mediate microbial interactions, shape bacterial diversity, and …

The traditional view of the stationary phase of the bacterial life cycle, obtained using
standard laboratory culture practices, although useful, might not always provide us with the …

Eubacteria inactivate their ribosomes as 100 S dimers or 70 S monomers upon entry into
stationary phase. In Escherichia coli, 100 S dimer formation is mediated by ribosome …

SUMMARY A biological attack on US crops, rangelands, or forests could reduce yield and
quality, erode consumer confidence, affect economic health and the environment, and …

The growth and persistence of rhizobia and bradyrhizobia in soils are negatively impacted
by drought conditions. In this study, we used genome-wide transcriptional analyses to obtain …

Resistance to chemotherapies, particularly to anticancer treatments, is an increasing
medical concern. Among the many mechanisms at work in cancers, one of the most …

The global dissemination of the mobilized colistin resistance gene, mcr-1, threatens human
health. Recent studies by our group and others have shown that the withdrawal of colistin as …

The rate of mutation is central to evolution. Mutations are required for adaptation, yet most
mutations with phenotypic effects are deleterious. As a consequence, the mutation rate that …

The contribution of antibiotic resistance originally selected for in the agricultural sector to
resistance in human pathogens is not known exactly, but is unlikely to be negligible. It is …

Colony phase variation is a regulatory mechanism at the DNA level which usually results in
high frequency, reversible switches between colonies with a different phenotype. A number …
