Parallel Acceleration of Evolutionary Rates in Symbiont Genes Underlying Host Nutrition

The overproduction of essential amino acids by Buchnera aphidicola, the primary bacterial mutualist of aphids, is considered an adaptation for increased production of nutrients that are lacking in aphids' diet of plant sap. Given their shared role in host nutrition, amino acid biosynthetic gene...
