Abstract: In the human pathogen Francisella tularensis, we have determined that changes in ribosome protein composition govern virulence gene expression. Our results indicate that ribosome composition in F. tularensis, either directly or indirectly, posttranscriptionally modulates gene expression and virulence. We propose a model in which a particular ribosomal protein homologs functions as a posttranscriptional regulator, allowing preferential translation of specific subsets of mRNAs. This work suggests that ribosome heterogeneity may permit many bacteria to posttranscriptionally regulate gene expression.
