Gene expression levels influence amino acid usage and evolutionary rates in endosymbiotic bacteria.

Gene - 6 Jun 2005

Abstract excerpt

Most endosymbiotic bacteria have extremely reduced genomes, accelerated evolutionary rates, and strong AT base compositional bias thought to reflect reduced efficacy of selection and increased mutational pressure. Here, we present a comparative study of evolutionary forces shaping five fully sequenced bacterial endosymbionts of insects. The results of this study were three-fold: (i) Stronger conservation of high...
