Promoter sequences are DNA sequences that define where transcription of a gene by RNA polymerase begins. Promoter sequences are typically located directly upstream or at the 5' end of the ...

Findings in yeast now suggest that variable tandem repeat (TR) sequences in promoter regions are a previously unrecognized cause of variability in transcription levels. This mechanism might make a ...

A new study published in PLOS Genetics has identified an extreme mutational hotspot within the genome of Pseudomonas ...

Max Planck researchers discovered a 5,000-fold increase in the mutation rate in the genome of *Pseudomonas fluorescens*. The mutation regularly occurred in the promoter region of the *rpoS* gene and ...
