title: Genomic organization of rDNA in Pseudomonas aeruginosa.
abstract: We have examined the number and organization of rRNA genes in Pseudomonas aeruginosa by hybridization of restriction nuclease digests of genomic DNA to 3'-32P-labelled 23 S, 16 S and 5 S rRNAs and corresponding labelled DNA from the rrnB operon of Escherichia coli. The immediate conclusion from these hybridization data is that there are 4 transcriptional units coding for rDNA in P. aeruginosa. We report here a putative model of the genomic organization of all 4 rDNA operons.
