Regulating rsmA Expression in Pseudomonas aeruginosa
… these hosts. The posttranscriptional regulator, RsmA, plays a role in the expression of many virulence factors in <em>P. aeruginosa</em>. RsmA up regulates virulence factors used in colonizing hosts. However, regulation of<em> rsmA</em> is not well elucidated. Transposon mutagenesis was performed …

Characterization of a novel virulence determinant in Erwinia carotovora subspecies atroseptica SCRI1043
… In many ways, RsmS acted in a similar fashion to RsmA, r a well characterized suppressor of virulence determinants (such as PCWDEs) and quorum sensing found in a wide variety of Gram-negative bacteria. RsmA activated rsmS transcription, and the transcription of both rsmS and rsmA was shown to be …

Novel pleiotropic regulators of gas vesicle biogenesis in Serratia
… Post-transcriptional regulators such as RsmA-rsmB were also known to be involved in the inverse regulation of gas vesicles and flagella based motility. Furthermore, gas vesicle formation, antibiotic production, and motility in S39006 were affected by cell population densities and …

The role of post-transcriptional regulators in pathogenesis and secondary metabolite production in Serratia sp. ATCC 39006.
… of another post-transcriptional regulator, RsmA, also involved in regulating prodigiosin production, was investigated by performing RNA-seq on an rsmA mutant. Moreover, global changes in the proteome of the hfq mutant was analysed using an LC-MS/MS approach with isobaric tags for relative …

THE IMPACTS OF ATMOSPHERICALLY DERIVED METALS ON COASTAL MARINE SYSTEMS
… concentrations in the Red Sea Marine Aerosol (RSMA) for the crustally sourced elements Al, Mn and Fe were higher (typically 2.7-3.1 times) than those detected at other comparative sites (i.e. Eastern Mediterranean). The aerosol population associated with the Middle and Southern Saudi Arabia …

Characterisation of pleiotropic regulators of gas vesicle biogenesis, antibiotic production, motility and virulence in Serratia sp. ATCC 39006
… which include the post-transcriptional regulator RsmA, the ribose operon repressor RbsR, the DeoR-family transcriptional regulator FloR, the sigma factor σ 54RpoN, and the transcription factor DksA. The regulation of GVs and secondary metabolites in S39006 can be coordinated but such pleiotropy is …

Identification of novel regulators of the necrosis-inducing protein (Nip) and carbapenem antibiotic production in the phytopathogen Pectobacterium
… Prior studies identified Hor, RpoS and RsmA as potential regulators of carbapenem. Three regulators of Nip have also been described: the small non-coding RNA rsmB and flagellar proteins FhlKL. Both are under quorum sensing control. In this study random transposon mutagenesis was used to …

Novel pleiotropic regulators of flotation, secondary metabolite production, and virulence in Serratia sp. ATCC 39006
… include the post-transcriptional regulator RsmA, the repressor of the ribose operon, RbsR, and the DeoR-family transcriptional regulator, FloR. This study employed random transposon mutagenesis, visual screening of mutant phenotypes, cloning and sequencing, and bioinformatic analysis to …
