Figure 4From: Phylogenetic diversification of glycogen synthase kinase 3/SHAGGY-like kinase genes in plantsMean number of inferred nucleotide substitutions by codon position based on the comparison of 139 GSK homologs. Subsets of the full data set are based on the results of the phylogenetic analysis of GSKs (green plants, moss, clade I, clade II, clade III, clade IV) or represent well-recognized organismal groups (angiosperms, monocots).Back to article page
