Structures of RNA polymerase enzymes have advanced our understanding of transcription initiation in all kingdoms of life. This Review discusses bacterial promoter structure, recent advances in our ...

While previous research had described bidirectional promoters in eukaryotes, as well as in a few bacteria and archaea species, the new study establishes divergent transcription—the reading of genes in ...

This mutation is directly linked to transcriptional activity: the more a promoter is active, the more frequently mutations appear in this promoter. In experiments where transcriptional activation ...

Researchers have typically done this by stuffing more combinations of promoters and regulators into a single bacterium, which, as we noted above, often runs into difficulties.

In bacterial transcription, sigma factors trigger recognition of a specific promoter — or a region of genetic information right at the start of the DNA sequence that's needed to produce a ...

Houseflies live close to humans and domesticated animals and because they are so mobile they can easily spread bacteria that ...

Bacteria from Tucson aphids all had heat-tolerant promoters. Bacteria from Michigan or New York state aphids were five to seven times more likely to have the heat-intolerant, mutated promoter.

Thus, though aphids containing bacterial symbionts with the heat-shock-promoter mutation fare worse than normal aphids after exposure to high temperatures, they do better under cool conditions ...
