Diversity of 23S rRNA genes within individual prokaryotic genomes. [PDF]
PLoS ONE, 2009 The concept of ribosomal constraints on rRNA genes is deduced primarily based on the comparison of consensus rRNA sequences between closely related species, but recent advances in whole-genome sequencing allow evaluation of this concept within organisms ...

Dumpster diving for diatom plastid 16S rRNA genes [PDF]
PeerJ, 2021 High throughput sequencing is improving the efficiency of monitoring diatoms, which inhabit and support aquatic ecosystems across the globe. In this study, we explored the potential of a standard V4 515F-806RB primer pair in recovering diatom plastid 16S

Compilation of 5S rRNA and 5S rRNA gene sequences [PDF]
Nucleic Acids Research, 1997 The compilation of 5S rRNA and 5S rRNA gene nucleotide sequences as of 30 September 1996, contains a total of 1661 primary structures of 5S rRNAs or their genes, which is an increase of 928 new sequence entries over the last compilation. It covers sequences from 54 archaea, 449 eubacteria, 34 plastids, nine mitochondria and 430 eukaryotes. The databank

Ribosomal DNA localization on Lathyrus species chromosomes by FISH
Journal of Genetic Engineering and Biotechnology, 2020 Background Fluorescence In Situ Hybridization (FISH) played an essential role to locate the ribosomal RNA genes on the chromosomes that offered a new tool to study the chromosome structure and evolution in plant. The 45S and 5S rRNA genes are independent

Polymorphism and gene conversion of the 16S rRNA genes in the multiple rRNA operons ofVibrio parahaemolyticus [PDF]
FEMS Microbiology Letters, 2005 The genome sequence of a strain of Vibrio parahaemolyticus holds 11 copies of rRNA operons (rrn) with identical 16S rRNA genes (rrs). Conversely, the species type strain contains two rrs classes differing in 10 nucleotide sites within a short segment of 25 bp.

Functional conservation of mitochondrial RNA levels despite divergent mtDNA organization
BMC Research Notes, 2020 Objective Mitochondria-encoded ribosomal RNA (rRNA) genes in humans are expressed at a higher rate than protein coding genes of the mitochondria. The organization of the human mitochondrial genome (mtDNA) is amenable to differential expression of rRNAs ...

A renaissance for the pioneering 16S rRNA gene [PDF]
Current Opinion in Microbiology, 2008 Culture-independent molecular surveys using the 16S rRNA gene have become a mainstay for characterizing microbial community structure over the past quarter century. More recently this approach has been overshadowed by metagenomics, which provides a global overview of a community's functional potential rather than just an inventory of its inhabitants ...

Epigenetic engineering of ribosomal RNA genes enhances protein production. [PDF]
PLoS ONE, 2009 Selection of mammalian high-producer cell lines remains a major challenge for the biopharmaceutical manufacturing industry. Ribosomal RNA (rRNA) genes encode the major component of the ribosome but many rRNA gene copies are not transcribed due to ...

Locus-specific ribosomal RNA gene silencing in nucleolar dominance. [PDF]
PLoS ONE, 2007 The silencing of one parental set of rRNA genes in a genetic hybrid is an epigenetic phenomenon known as nucleolar dominance. We showed previously that silencing is restricted to the nucleolus organizer regions (NORs), the loci where rRNA genes are ...
