Intraspecific diversity of the 23S rRNA gene and the spacer region downstream in Escherichia coli.

Journal of bacteriology - 1 May 1999

Antón A I, Martínez-Murcia A J, Rodríguez-Valera F

Abstract excerpt

The molecular microevolution of the 23S rRNA gene (rrl) plus the spacer downstream has been studied by sequencing of different operons from some representative strains of the Escherichia coli ECOR collection. The rrl gene was fully sequenced in six strains showing a total of 67 polymorphic sites, a level of variation per nucleotide similar to that found for the 16S rRNA gene (rrs) in a previous study. The size of...
