Phylogeny of SnRK1s and MAP2Ks. (A) Phylogeny of SnRK1 showing orthology with SNF1 in S. cerevisiae and AMPKs in H. sapiens. Brain-Specific Kinase (BRSK) acts as an outgroup. The full set of SnRKs are reported in Additional file 7: Figure S5D. (B) Phylogeny of MAP3K revealing distinct YDA- and CDC15-like MAP3Ks in O. tauri. It shows a strong conservation within the S. cerevisiae and plant cell cycle kinase CDC15 (not present in H. sapiens or other metazoa). The large numbers of MAP3K proteins in other species are reduced to a single member in O. tauri. A general explanation for phylogenies is in Figure 2. Raw branch lengths (red) are annotated to broken-line arrows and show the distances from O. tauri kinases to their orthologous sequences in A. thaliana, S. cerevisiae, and H. sapiens. S. cerevisiae identifiers are standard names from SGD.
