  1. +/- indicates in proteobacteria that it did not occur in some proteobacteria, if this is missing only in Buchnera and Wolbachia, this is specifically indicated by (no B. W.).
  2. +/- indicates in bacteria general that it did occur in some non-proteobacteria but was not wide spread. "?" indicates the protein is still unknown in its function (Bfl377 and Bfl064 can be associated with functions, see text and Additional file 2). 1This gene is absent in one of the three Buchnera genomes (BAp). 2This gene is absent in one of the three Buchnera genomes (BBp).
