Figure 6.

Comparison of NJ and MP trees. The tree shown is an NJ tree subjected to 5,000 bootstrap trials. Bootstrap values are shown as percentages with MP bootstrap values shown in parentheses. Differences in the MP tree are denoted by bold lines (multifurcations) and dashed arrow (variable position), and an asterisk indicates rooting at the base of the tree. Note the distribution of cyanobacterial sequences in the tree: two sequences from Anabaena sp. PCC 7120 and N. punctiforme branch with vascular plants; two sequences from N. punctiforme and Synechococcus branch distantly with Thermotogales and Proteobacteria; and three sequences from Synechocystis, N. punctiforme, and Anabaena, which are most likely CSL proteins, group with Bacillus subtilis. The high bootstrap values support the validity of the tree.
