A phylogenetic tree of the septins in Saccharomyces cerevisiae (Sc), Schizosaccharomyces pombe (Sp), Caenorhabditis elegans (Ce), Drosophila melanogaster (Dm) and humans (Hs). The longest amino-acid sequence among the putative polypeptides generated by each gene was analyzed with the software Phylip [59] using the default mode with the UPGMA method, 1,000 bootstrap replicates and systematic tie-breaking, and Poisson-corrected distances with proportionally distributed gaps. The numbers of predicted coiled coils are shown in parentheses. The scale bar represents 0.1 substitutions.
