Figure S1. Phylogenetic relationships of Ostreococcus, Micromonas, Volvox, Chlamydomonas, Physcomitrella, Selaginella, Arabidopsis and Naegleria MKKs and human MEK1. Lower plant MPK proteins were identified by using Arabidopsis query sequences in BLAST (http://blast.ncbi.nlm.nih.gov/) with individual organism sets. Retrieved sequences were filtered for the presence of the dual-specificity protein kinase catalytic domain consensus, the plant-specific MKK activation loop motif GTxxYMSPER and the plant-specific MKK phosphorylation site motif, [ST]xxxxx[ST]. Sequence alignment and phylogenetic analyses were conducted in the MEGA5 software suite (Tamura et al., Mol Biol Evol. 2011, 28:2731-9. PMID: 21546353). Protein kinase domains of each sequence were aligned by the MUSCLE alignment tool, using the following parameters: gap opening penalty: -2.9, gap extension penalty: -0.01, hydrophobicity multiplier: 1.2. The evolutionary history was inferred by using the Maximum Likelihood method based on the JTT matrix-based model. The bootstrap consensus tree inferred from 500 replicates is taken to represent the evolutionary history of the taxa analyzed. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (500 replicates) are shown next to the branches. Initial tree(s) for the heuristic search were obtained automatically as follows. When the number of common sites was < 100 or less than one fourth of the total number of sites, the maximum parsimony method was used; otherwise BIONJ method with MCL distance matrix was used. The tree is drawn to scale, with branch lengths measured in the number of substitutions per site. All positions containing gaps and missing data were eliminated. Proteins are designated by accession numbers (AGI numbers in case of Arabidopsis). Sequences are shown on a background coloured according to species for visual clarity. Species are indicated by the following abbreviations: ota: Ostreococcus tauri, olu: Ostreococcus lucimarinus, mic: Micromonas sp. RCC299, vol: Volvox carteri, chl: Chlamydomonas reinhardtii, phy: Physcomitrella patens, sel: Selaginella moellendorffii. Human MEK1 is indicated with the species acronym Hs. A, B, C, D and intermediate indicate A, B, C, D and ‘intermediate’ phylogenetic groups.

Figure S2. Phylogenetic relationships of Ostreococcus, Micromonas, Volvox, Chlamydomonas, Physcomitrella, Selaginella, Arabidopsis and Naegleria MAPKs and human MAPKs, representing major types of human MAPKs. Lower plant MPK proteins were identified by using Arabidopsis query sequences in BLAST (http://blast.ncbi.nlm.nih.gov/) with individual organism sets. Retrieved sequences were filtered for the presence of the serine/threonine kinase catalytic domain consensus, the plant-specific MAPK activation loop motifs (FMTEYVVTRWYRAPEL in case of TEY-type MAPKs, FWTDYVATRWYRAPEL in case of TDY-type MAPKs and PYT[ED]YVSTRWYRAPE in case of MHK-type kinases) including the MAPK phosphorylation site motif TxY. Sequence alignment and phylogenetic analyses were conducted in MEGA5 software suite (Tamura et al., Mol Biol Evol. 2011, 28:2731-9. PMID: 21546353).
