Fig. 2.

Multiple sequence alignment of common bean (Phaseolus vulgaris) CLE pre-propeptides. Related sequences tend to align closer together. Shading of amino acid residues represents conservation, with the darker the shading the more highly conserved the residues. As with the soybean prepropeptides shown in Fig. 1, 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.
