Abstract
Ribosomal RNA gene dosage was determined for 20 marine heterotrophic b acteria using short probes (< 600 bp) from the Escherichia coli 16S rR NA gene and Southern blot analysis. All bacterial strains had between 4 and 10 copies of the 16S rRNA genes in their genomes. This report pr esents important preliminary data for developing quantitative molecula r methods to address population dynamics of marine bacteria based on 1 6S rRNA sequences.
