The essential yhcSR two-component signal transduction system directly regulates the lac and opuCABCD operons of Staphylococcus aureus. [PDF]
PLoS ONE, 2012 Our previous studies suggested that the essential two-component signal transduction system, YhcSR, regulates the opuCABCD operon at the transcriptional level, and the Pspac-driven opuCABCD partially complements the lethal effects of yhcS antisense RNA ...

Advanced Science, Volume 13, Issue 23, 23 April 2026.Dimethylsulfoniopropionate (DMSP) is a major marine organosulfur compound central to climate‐relevant dimethyl sulfide (DMS) production. In Halomonas sp. D47, DMSP catabolism is revealed to be coordinated by two transcriptional regulators, AcuR and AcuZ, which control gene expression by sensing DMSP and its metabolites.

PLoS Computational Biology, 2012 Bacterial chromosomes are organized into polycistronic cotranscribed operons, but the evolutionary pressures maintaining them are unclear. We hypothesized that operons alter gene expression noise characteristics, resulting in selection for or against ...

Rhizobial motility preference in root colonization of Medicago truncatula
New Phytologist, Volume 250, Issue 1, Page 547-562, April 2026.Summary Tunnel‐like infection thread (IT) structures support root colonization by symbiotic nitrogen‐fixing rhizobia bacteria in most legume species. These tip‐grown structures are key to directing rhizobia from root hairs to developing nodules, where they are hosted to fix nitrogen.

Transient repression of the lac operon — the effect of a lac promoter deletion [PDF]
FEBS Letters, 1970 Experiments have been done to show whether the lac promoter delection L1, which partly alleviates catabolite repression, also affects transient repression of lac. In stain L1/F′M15 all of the β‐galactosidase is synthesized from a chromosomal gene cis to L1, whereas 98% of the thiogalactosidase transacetylase is synthesized from an episomal gene cis to ...
