2. Figure 1 A Schematic Tree of All Yeast Protein Kinases
The schematic is based on a maximum likelihood tree for all yeast kinases (our unpublished data) and on the phylogeny in reference [5]. The kinase family names are in capital bold text, and representative CCC kinases are in capital bold italics.

3. Figure 2
A Maximum Likelihood Phylogenetic Tree of the CDC28 Family of Yeast Protein Kinases
The root of the tree is marked with a red circle. Bootstrap values are shown next to internal nodes. Kinases involved solely in meiosis are highlighted in blue, those involved solely in mitosis are highlighted in yellow, and those involved in both processes are highlighted in gray. The Cak1p kinase that belongs to the CDC28 family, but which has no detectable orthologs in eukaryotes other than yeasts and has been shown to form a long branch in trees [9], was omitted. The following gene identification numbers correspond to kinase sequences used for tree construction: Ptk2p, Ptk1p, Chk1p, Gcn2p, Cak1p, Ime2p, Sky1p, Yak1p, Kns1p, Ssn3p, Ctk1p, Sgv1p, Kin28p, Pho85p, Cdc28p, Hog1p, Smk1p, Ykl161cp, Slt2p, Kss1p, Fus3p, Mrk1p, Mds1p, Mck1p, Yol128cp, Prr2p, Npr1p, Ydl025cp, Yor267cp, Sat4p, Kkq8p, and Hal5p.

4. Figure 3
A Maximum Likelihood Phylogenetic Tree of the Conserved CDC28 Family Kinases from Seven Eukaryotic Species
The color code and designations are as in Figure 2. Clades with kinases not involved in CCC are boxed with a dashed line. The CMK1 clade is used as the outgroup.

5. Figure 4
A Maximum Likelihood Phylogenetic Tree of the DBF Family of Yeast Protein Kinases
The designations are as in Figure 2. The following gene identification numbers correspond to kinase sequences used for tree construction: Ipl1p, Ydr466wp, Phk1p, Phk2p, Rim15p, Cbk1p, Dbf20p, Dbf2p, Kin82p, and Ynr047wp.
