50% majority rule consensus tree of 77 most parsimonious trees (length = 2156; CI = 0.4935; RI = 0.7532) of GSK3/SHAGGY-like kinase proteins from plants, animals, protists, and fungi based on sequence alignment of the 348 amino acids of the catalytic domain and part of the C terminus. Numbers above the branches are bootstrap values; only values over 50% are indicated. Arrows on the nodes indicated the collapsed braches in the strict consensus tree. Orange labels indicate GSK proteins from Arabidopsis, and blue labels designate rice proteins. GSK proteins inferred from FGP ESTs are labeled in red, and those from Pinus ESTs are labeled in green.
