This chapter takes a different approach by considering the contribution of the genetic material itself to gene regulatory processes. DNA is often regarded as a passive partner in the gene regulatory relationship, a mere substrate on which th

An important form of gene control is through the use of alternative sigma factors that direct RNA polymerase to recognize a distinct group of genes. One such sigma factor is RpoS, which is widely present in many Gram-negative bacteria. RpoS is important for ad
