Abstract.

The aphid Uroleucon sonchi contains a prokaryotic endosymbiont (Buchnera) with plasmids having trpEG as well as remnants of trpE pseudogenes. In this respect it resembles Buchnera from the aphid Diuraphis noxia. Phylogenetic trees based on trpE (plasmid gene) and trpB (chromosomal genes) from eight species of aphids are congruent, indicating a lack of exchange of plasmids among endosymbionts from different aphid species.
