Comparison of unrooted phylogenetic trees of the head, neck, and
tail domains of the heavy chains of class II myosins. These trees are
not displayed in radial form (as in Fig. 1) because some of the
subgroups are too tightly clustered to be readily visualized in that
format. The scale bars of percent divergence are different lengths for
the three trees. ●, Nodes found in 100% of
bootstrap trials; ○, nodes found in >95% of bootstrap
trials; ■, nodes found >90% of bootstrap trials;
□, nodes found in >80% of bootstrap trials. The same
results were obtained for the neck domains after 10,000 bootstrap
trials and when the order of sequence entry was changed. The GenBank
accession numbers for each myosin and, in parentheses, the residue
numbers used to define the head and neck/tail domains are: Ac, P05659
