Figure 8
Schematic drawing of the evolution of myosin diversity. The tree has been constructed based on the combination of the phylogenetic information obtained from the analysis of single myosin classes as well as the analysis of the class distribution of major taxa (see Materials and methods). Thus, branch lengths do not correspond to any scale. Nodes that have already been suggested are symbolized by filled circles. Nodes that we propose base on the analysis of the myosins are represented by open circles. The exact myosin contents of several representative organisms are given. The myosin inventory of all 328 organisms is available from Additional data file 3.
