Peptide hormones have emerged as an important class of signaling molecules that mediate developmental signals between plant cells. Membrane-bound receptors bind specific extracellular peptide ligands to mediate communication between cells. In this review, we summarize novel peptide hormones identified in recent studies with an emphasis on their molecular structures. By focusing on the CLE family peptides, we will describe the details of their physiological roles in various plant species, which include Arabidopsis, crop species, and bryophyte models.
