A segment of the 16S rRNA tree, with the predicted number for protein families at each node displayed (green), and the number of families gained (red) or lost (blue) for each branch. The genomes represented in this tree segment are: Campylobacter jejuni (CJEJ), Helicobacter pylori strains 26695 (HPYL-2) and J99 (HPYL-J), Mesorhizobium loti (MLOT), Caulobacter crescentus (CCRE), Rickettsia prowazekii (RPRO), Xyllela fastidiosa (XFAS), and Neisseria meningitidis strains Z2491 (NMEN-Z) and MC58 (NMEN-M).
