Figure 1From: Extensive horizontal transfer of core genome genes between two Lactobacillus species found in the gastrointestinal tractProtein family occurrence profiles. Profiles are listed in decreasing order of abundance. Symbols indicate the species in which the protein families are present: a, L. acidophilus (genome size 2.0 Mbp, 1659 protein families); d, L. delbrueckii (genome size 1.9 Mbp, 1849 protein families); j, L. johnsonii (genome size 2.0 Mbp, 1630 protein families); p, L. plantarum (genome size 3.3 Mbp, 2630 protein families); s, L. sakei (genome size 1.9 Mbp, 1731 protein families). *, profiles equally compatible with any tree topology. The inset highlights four couples of profiles compatible with the monophyly of the acidophilus complex.: (p.,s.) vs. (a.,d.,j.) equally compatible with any of the three tree topologies depicted in Fig. 2, (a.,d.) vs (j.,p.,s.), (a.,j.) vs. (d.,p.,s.), (d.,j.) vs. (a.,p.,s.) compatible with a single gain or loss event in topology Ta, Tb and Tc, respectively.Back to article page
