Intragenomic variation and evolution of the internal transcribed spacer of the rRNA operon in bacteria.

Journal of molecular evolution - 1 Jul 2007

Stewart Frank J, Cavanaugh Colleen M

Abstract excerpt

Variation in the internal transcribed spacer (ITS) of the rRNA (rrn) operon is increasingly used to infer population-level diversity in bacterial communities. However, intragenomic ITS variation may skew diversity estimates that do not correct for multiple rrn operons within a genome. This study characterizes variation in ITS length, tRNA composition, and intragenomic nucleotide divergence across 155 Bacteria...
