Figure S3. Protein domain comparison of intermediate clade WOX proteins from A. thaliana and C. richardii. (a) Model of intermediate clade WOX proteins from C. richardii and A. thaliana, green boxes represent the homeodomain and blue the C-terminal domain. (b) T-Coffee sequence alignment of C. richardii and A. thaliana intermediate WOX proteins domains. Specific motifs are outlined, and conserved residues are highlighted in green, less conserved sites are highlighted in yellow. (DOCX 160 kb)
