Fig. 1.

Multiple sequence alignment of soybean (Glycine max) CLE pre-propeptides. Homeologous copies consistently align together, as do other closely related sequences. Shading of amino acid residues represents conservation, with the darker the shading the more highly conserved the residues. The CLE domain and the leucine-rich region of the signal peptide domain exhibit the greatest degree of conservation across the entire pre-propeptide family.
