Structural representation of two cysteine-rich peptides (CRPs): Left panel, ribbon diagram showing the NMR structure of Stomagen (EPFL9) (PDB ID 2LIY) with cysteine residues shown in green colored stick representation. Stomagen is responsible for regulating the stomatal density on leaves. Right panel, ribbon diagram showing the crystal structure of AtLURE1.2 (PDB ID 5Y9W) peptide with cysteine residues represented by stick representation and colored in slate. AtLURE1.2 peptide is important for pollen tube development and ovule targeting.
