Abstract
The recent discovery of the phenomenon that some prokaryotes fragment their 23S rRNA during post-transcriptional processing of precursor rRNA has been shown to be particularly prevalent among strains and species of Salmonella. Some strains of Salmonella cleaved 23S rRNA at multiple sites producing several fragments. The cleavage patterns of 23S rRNA differed among Salmonella strains and sometimes among the rRNA operons in the same strain. Fragmentation of 23S rRNA was not observed in strains of the closely related species Escherichia coli. Fragmentation of 23S rRNA occurred in Brucella and Agrobacterium but the cleavage pattern was not as diverse as that demonstrated in Salmonella. Introduction of cleavage sites into precursor 23S rRNA of Salmonella is probably a recent evolutionary event.
