3 and 4 Phylogenetic tree. The tree shown above was built from a kinesin motor domain sequence alignment using the heuristic search method of PAUP v4.0b6, a maximum parsimony program, with random stepwise addition and tree bisection-reconnection (TBR). The tree is the consensus tree from 68 trees built from 100 replicates. It is arbitrarily rooted using ScSmy1 as an outgroup. Vertical dashes indicate ungrouped kinesins (light dashes - those grouped with other kinesins, bold dashes - exclusively Arabidopsis kinesins). The Arabidopsis kinesins are in bold. Kinesins from the following organisms were used: An, Aspergillus nidulans; Bm, Bombyx mori; Ce, Caenorhabditis elegans; Cf, Cylindrotheca fusiformis; Cg, Cricetulus griseus; Cr, Chlamydomonas rheinhardtii; Dd,Dictyostelium discoideum; Dm, Drosophila melanogaster; Gg, Gallus gallus; Hs, Homo sapiens; Lc, Leishmania chagasi; Lm, Leishmania major; Lp, Loligo pealii; Mm, Mus musculus; Ms, Morone saxatilis; Nc, Neurospora crassa; Nh, Nectria haematococca; N, Nicotiana tabacum; St, Solanum tuberosum; Rn, Rattus norvegicus; Sc, Saccharomyces cerevisiae; Sp, Strongylocentrotus purpuratus; Spo, Schizosaccharomyces pombe; Sr, Syncephalastrum racemosum; Um, Ustilago maydis; Xl, Xenopus laevis.
