A family of gram-negative, moderately halophilic bacteria in the order Oceanospirillales. Members of the family have been isolated from temperate and Antarctic saline lakes, solar salt facilities, saline soils, and marine environments.

A genus of gram-negative, rod-shaped or pleomorphic bacteria which are halotolerant. Members of this genus are capable of growth in sodium chloride concentrations of up to 20% or more. (From Bergey's Manual of Determinative Bacteriology, 9th ed)

DNA sequences encoding RIBOSOMAL RNA and the segments of DNA separating the individual ribosomal RNA genes, referred to as RIBOSOMAL SPACER DNA.

Constituent of 30S subunit prokaryotic ribosomes containing 1600 nucleotides and 21 proteins. 16S rRNA is involved in initiation of polypeptide synthesis.

Constituent of 50S subunit of prokaryotic ribosomes containing about 3200 nucleotides. 23S rRNA is involved in the initiation of polypeptide synthesis.

Genes, found in both prokaryotes and eukaryotes, which are transcribed to produce the RNA which is incorporated into RIBOSOMES. Prokaryotic rRNA genes are usually found in OPERONS dispersed throughout the GENOME, whereas eukaryotic rRNA genes are clustered, multicistronic transcriptional units.

The relationships of groups of organisms as reflected by their genetic makeup.

A multistage process that includes cloning, physical mapping, subcloning, determination of the DNA SEQUENCE, and information analysis.

Deoxyribonucleic acid that makes up the genetic material of bacteria.

Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
