Below are four (Figures 2 and 4 from their paper) of the parsimonious trees generated by the analysis of Daubin et al (2002).

Daubin, Vincent, Manolo Gouy, and Guy Perrière.  2002.  A Phylogenomic Approach to Bacterial Phylogeny: Evidence of a Core of Genes Sharing a Common History. Genome Research 12 (7): 1080-1090.

Figure 2 (A & B above).   Supertrees of 45 species constructed with 730 trees. (A) Supertree based on trees made by BIONJ and a gamma distribution estimation of evolutionary rate heterogeneity. (B) Supertree made with ML trees. Only bootstrap values over 50% are shown.

Figure 4 (A & B above).   Supertrees of 45 species built with the trees selected using the PCO results. (A) Supertree based on 121 trees made by BIONJ and a gamma distribution estimation of evolutionary rate heterogeneity. (B) Supertree based on 118 ML trees.
