Non‐conserved microRNAs and their roles in plants: the case for legumes
Non‐conserved miRNAs are functional and modulate stress and microbial interactions in legumes, hinting at broader roles in plant gene regulation. Abstract Several classes of small RNAs function to regulate stress and development pathways in all kingdoms of life.

No detectable effect of RNA-binding protein Hfq absence in
Background The RNA-binding protein Hfq is involved in stress and virulence of several pathogens, probably due to its role as mediator in small RNA (sRNA)-mRNA interactions.

Sm‐like protein Hfq: Location of the ATP‐binding site and the effect of ATP on Hfq–RNA complexes [PDF]
AbstractSm‐like proteins are ubiquitous ring‐shaped oligomers that exhibit a variety of nucleic acid‐binding activities. They have been linked functionally to various cellular events involving RNA, and it is generally believed that their activity is exerted via the passive binding of nucleic acids.

A quantitative comparison of sRNA-based and protein-based gene regulation [PDF]
Small, non-coding RNAs (sRNAs) play important roles as genetic regulators in prokaryotes. sRNAs act post-transcriptionally via complementary pairing with target mRNAs to regulate protein expression.

The quorum sensing regulated sRNA Lrs1 participates in the adaptation of Pseudomonas aeruginosa in low iron by downregulating the siderophore pyochelin, the Quorum Sensing system PQS, and its associated virulence factor phenazines. ABSTRACT Iron is an essential nutrient for microbial growth. The opportunistic pathogen Pseudomonas aeruginosa can survive

Hfq affects mRNA levels independently of degradation [PDF]
Abstract Background The bacterial Lsm protein, Hfq, is an RNA chaperone involved in many reactions related to RNA metabolism, such as replication and stability, control of small RNA activity and polyadenylation. Despite this wide spectrum of known functions, the global role of Hfq is almost certainly undervalued; its ...

Hfq regulates the expression of the thermostable direct hemolysin gene in
Background The hfq gene is conserved in a wide variety of bacteria and Hfq is involved in many cellular functions such as stress responses and the regulation of gene expression.

Identification, characterization and classification of prokaryotic nucleoid‐associated proteins
Nucleoid‐associated proteins (NAPs) structure DNA by either bending, wrapping, bridging, or forming protein filaments on the DNA. We review newly identified NAPs and provide a list of simple biochemical assays to study the DNA‐structuring properties of novel NAPs. Abstract Common throughout life is the need to compact and organize the genome.
