Methods to Identify New Partners of Plant Signaling Peptides
Over the last decade, there has been an increasing awareness of the importance of cell-to-cell communication in plants by peptide ligands and membrane-bound receptors due to striking aberrant phenotypes caused by synthetic peptides, overexpression of peptides, or mutations in peptide or receptor genes. The number of experimentally confirmed peptide-receptor signaling modules represents only a tiny fraction of the number of genes encoding putative ligands and receptors in Arabidopsis thaliana. Thus, a major challenge in plant biology is to identify new partners of plant signaling peptides. Here we present an overview of methods and prerequisites for ligand–receptor matchmaking with examples from current literature.
