The paper analyzes RM system sharing in bacterial strains and models phage-bacteria dynamics to identify non-random network structures and two bacterial strategies.

This paper shows that Mtb's SufR senses NO via its 4Fe-4S cluster, regulates Fe-S cluster biogenesis, and supports persistence in mice.

This paper identifies an RpoC mutation that enhances σS activity in E. coli, enabling adaptation to late prolonged stationary phase by balancing growth and stress tolerance.

The paper examines genetic variation in bacterial transcription factors and their target genes, finding TFs less diverse due to regulatory roles, with mutations initially common but declining over time.

This paper identifies WhiB4 as a redox-dependent nucleoid condensing protein in Mtb that links oxidative stress response with genome organization and gene expression.

The paper measures cell division and death rates in E. coli under antibiotic treatment and shows molecular noise drives exponential growth and decay kinetics.
