Direct Proof for the Presence and Expression of Two 5% Different 16S rRNA Genes in Individual Cells of Haloarcula Marismortui

Extremophiles. 2000 Dec;4(6):373-6. doi: 10.1007/s007920070007.


A single-cell-derived pure culture of Haloarcula marismortui was obtained using the optical tweezers technique. Analysis of the 16S rRNA genes unambiguously demonstrated two 5% different 16S rRNA sequences. In addition, expression of both operons in the same cell was shown by fluorescence in situ hybridization with operon-specific probes.
