Unique organization of Leptospira interrogans rRNA genes [PDF]

open access: yesJournal of Bacteriology, 1989
We cloned Sau3AI fragments containing the rRNA genes for Leptospira interrogans serovar canicola strain Moulton in the BamHI site of lambda EMBL3 bacteriophage DNA. Physical maps of the fragments were constructed, and the locations of the rRNA genes were determined by Southern blot hybridization and S1 protection.

Systematic identification of gene families for use as markers for phylogenetic and phylogeny- driven ecological studies of bacteria and archaea and their major subgroups [PDF]

open access: yes, 2013
With the astonishing rate that the genomic and metagenomic sequence data sets are accumulating, there are many reasons to constrain the data analyses.

Sensitivity and correlation of hypervariable regions in 16S rRNA genes in phylogenetic analysis

open access: yesBMC Bioinformatics, 2016
Prokaryotic 16S ribosomal RNA (rRNA) sequences are widely used in environmental microbiology and molecular evolution as reliable markers for the taxonomic classification and phylogenetic analysis of microbes.

Regulation of Arabidopsis thaliana 5S rRNA Genes [PDF]

open access: yesPlant and Cell Physiology, 2007
The Arabidopsis thaliana genome comprises around 1,000 copies of 5S rRNA genes encoding both major and minor 5S rRNAs. In mature wild-type leaves, the minor 5S rRNA genes are silent. Using different mutants of DNA methyltransferases (met1, cmt3 and met1 cmt3), components of the RNAi pathway (ago4) or post-translational histone modifier (hda6/sil1), we ...

Information about variations in multiple copies of bacterial 16S rRNA genes may aid in species identification.

open access: yesPLoS ONE, 2019
Variable region analysis of 16S rRNA gene sequences is the most common tool in bacterial taxonomic studies. Although used for distinguishing bacterial species, its use remains limited due to the presence of variable copy numbers with sequence variation ...

Nitrogen removal in a two-chambered microbial fuel cell: Establishment of a nitrifying-denitrifying microbial community on an intermittent aerated cathode [PDF]

open access: yes, 2016
A microbial fuel cell (MFC) was used to study nitrogen dynamics and its feasibility for high strength wastewater treatment. Intermittent aeration was applied on the cathode chamber accomplishing the establishment of a simultaneous nitrifying-denitrifying

The complete chloroplast genome sequence of Chlorella vulgaris and phylogenetic analysis

open access: yesMitochondrial DNA. Part B. Resources, 2020
To understand the process of chloroplast genome evolution, information on repeated sequences, intergenic regions, and pseudogenes in chloroplast DNA is extremely helpful.

Small and mighty: adaptation of superphylum Patescibacteria to groundwater environment drives their genome simplicity. [PDF]

open access: yes, 2020
BackgroundThe newly defined superphylum Patescibacteria such as Parcubacteria (OD1) and Microgenomates (OP11) has been found to be prevalent in groundwater, sediment, lake, and other aquifer environments.
