D. Lodwick et al., THE PHYLOGENETIC POSITION OF THE HALOALKALIPHILIC ARCHAEON NATRONOBACTERIUM-MAGADII, DETERMINED FROM ITS 23S RIBOSOMAL-RNA SEQUENCE, Systematic and applied microbiology, 17(3), 1994, pp. 402-404
The nucleotide sequence of the 23S and 5S rRNA genes from the haloalka
liphilic archaeon Natronobacterium magadii were determined by analysis
of cloned DNA. A phylogenetic tree for the halobacteria was produced
by alignment of the 23S rRNA sequence with those of other archaea. Thi
s analysis confirms that the genus Natronobacterium forms a distinct l
ineage within the halobacteria, and that the halobacterial genera dive
rged over a relatively short time interval.
