(Submitter supplied) Small RNAs have been studied in detail in Bacteria and Eukarya domain, but in the case of Archaea domain the knowledge is scarce and the physiological function of the majority is still uncertain. To extend the knowledge of sRNAs in Archaea domain and its possible role in the regulation of the nitrogen assimilation metabolism in haloarchaea, Haloferax mediterranei has been used as a model microorganism. more...

(Submitter supplied) We demonstrate here the transcriptional landscape and functional roles of sRNAs specifically in the regulation of the oxidative stress response of the model haloarchaeon Haloferax volcanii. We sequenced 5 biological replicates of H. volcanii strain H53 under no challenge and oxidative stress (H2O2) conditions at mid-exponential phase (OD 0.4). Thousands of sRNAs, both intergenic and antisense, were discovered using strand-specific sRNA-seq, comprising around 30% of the transcriptome during non-challenged and oxidative stress conditions. more...

(Submitter supplied) The transcriptional analysis of the HM26-ΔSm1 deletion mutant versus the parental strain HM26 was performed under nitrogen and carbon starvation for 120 h. These contrasts allow us to analyze the effect that the deletion of the Sm1 motif has under these conditions and, therefore, allow us to know which genes are regulated by the Lsm protein under the conditions analyzed.

(Submitter supplied) Transcriptional profiling of Haloferax mediterranei in three culture media with different nitrogen sources: a) cells were grown stationary and exponentially on ammonium, b) cells were grown exponentially on nitrate, and c) cells were shifted to nitrogen starvation conditions. The main differences in the transcriptional profiles have been identified between the cultures with ammonium as nitrogen source and the cultures with nitrate or nitrogen starvation, supporting previous results which indicate the absence of ammonium as the factor causing the expression of genes involved in nitrate assimilation pathway.

(Submitter supplied) Transcriptional profiling of Haloferax mediterranei DglnA and HM26 strains in two different culture media: a) cells were grown exponentially on complex media + 40 mM Gln, b) cells were shifted to nitrogen starvation conditions (72h). In the Nsta(∆glnA)-Cx and Nsta-Cx contrasts, glnA2 was up-regulated, and glnA3 did not show any difference. Therefore, glnA2 and glnA3 were unable to compensate lack of glnA because either they do not properly encode GS or are not expressed under the same conditions.

(Submitter supplied) Denitrification, a crucial biochemical pathway prevalent among haloarchaea in hypersaline ecosystems, has garnered considerable attention in recent years due to its ecological implications. Nevertheless, the underlying molecular mechanisms and genetic regulation governing this respiration/detoxification process in haloarchaea remain largely unexplored. In this study, RNA-sequencing was used to compare the transcriptomes of the haloarchaeon Haloferax mediterranei under oxic and denitrifying conditions, shedding light on the intricate metabolic alterations occurring within the cell such as the accurate control of the metal homeostasis. more...

(Submitter supplied) Small RNAs (sRNAs) have emerged as important regulatory molecules and have been studied in several bacteria. However, to date, there have been no whole-transcriptome studies on sRNAs in any of the Soft Rot Enterobacteriaceae (SRE) group of pathogens. Although the main ecological niches for these pathogens are plants, a significant part of their life cycle is undertaken outside their host within the adverse soil environment. more...

(Submitter supplied) Accurate annotation of regulatory RNAs is a complex task but nevertheless essential as sRNA molecular and functional studies ensue from it. Several formerly considered small RNAs (sRNA) are now known to be parts of UTR transcripts. In light of experimental data, we review hundreds of Staphylococcus aureus putative regulatory RNAs. We pinpoint those that are likely acting in trans and are not expressed from the opposite strand of a coding gene. more...
