The human intestinal microbiome is a microbial ecosystem that expresses as many as 100
times more genes than the human host, thereby constituting an important component of the …

Small RNAs are ubiquitously present regulators in all kingdoms of life. Most bacterial and
archaeal small RNAs (sRNAs) act by antisense mechanisms on multiple target mRNAs …

Iron is a vital nutrient for virtually all forms of life. The requirement for iron is based on its role
in cellular processes ranging from energy generation and DNA replication to oxygen …

Small RNA regulators (sRNAs) have been identified in a wide range of bacteria and found to
play critical regulatory roles in many processes. The major families of sRNAs include true …

Bacteria possess numerous and diverse means of gene regulation using RNA molecules,
including mRNA leaders that affect expression in cis, small RNAs that bind to proteins or …

Transcriptome-wide studies in eukaryotes have been instrumental in the characterization of
fundamental regulatory mechanisms for more than a decade. By contrast, in prokaryotes …

Antisense RNAs encoded on the DNA strand opposite another gene have the potential to
form extensive base-pairing interactions with the corresponding sense RNA. Unlike other …

Microorganisms play a dominant role in the biogeochemical cycling of nutrients. They are
rightly praised for their facility for fixing both carbon and nitrogen into organic matter, and …

The stress-induced small RNAs SgrS and RyhB in Escherichia coli form a specific
ribonucleoprotein complex with RNAse E and Hfq resulting in translation inhibition, RNAse …

Organisms of the third domain of life, the Archaea, share molecular characteristics both with
Bacteria and Eukarya. These organisms attract scientific attention as research models for …
