Molecular characterization of DNA encoding 16S-23S rRNA intergenic spacer regions and 16S rRNA of pectolytic Erwinia species.
Sequences of 16S rDNAs and the intergenic spacer (IGS) regions between the 16S and 23S rDNA of bacterial strains from genus Erwinia were determined. Comparison of 16S rDNA sequences from differentExpand
