ABSTRACT Buchnera aphidicola BCc has lost its symbiotic role as the tryptophan supplier to the aphid Cinara cedri . We report the presence of a plasmid in this endosymbiont that contains the trpEG genes. The remaining genes for the pathway ( trpDCBA ) are located on the chromosome of the secondary endosymbiont “ Candidatus Serratia symbiotica.” Thus, we propose that a symbiotic consortium is necessary to provide tryptophan.
