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 ...

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.

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.

The research, conducted by Andrew D. Farr, Christina Vasileiou, Peter A. Lind, and Paul B. Rainey, reveals that mutations in the promoter region of the rpoS gene occur at an astonishing rate ...

Newly discovered bacterial transcription mechanism may inform synthetic biology engineering ... The comparison of SigI and a canonical σ 70 factor in -35 and -10 promoter recognition.

They discovered that short-promoter bacteria-bearing aphids produced progeny faster than did the normal ones when raised at 15 °C or 20 °C.

The aphid Acyrthosiphon pisum depends on a bacterial symbiont, Buchnera aphidicola, for amino acids it can't get from plants. The aphid, in turn, provides the bacterium with energy and carbon as ...
