Peptide signalling in plant development and self/non-self perception

Curr Opin Cell Biol. 2005 Apr;17(2):116-22. doi: 10.1016/


Plant genomes contain very large families of genes encoding receptor-like kinases (RLKs). In recent years, several of these RLKs have been shown by biochemical and mutational analysis to represent receptors for peptides, and the emerging picture shows that peptide signalling in development and self/non-self perception is based on a similar repertoire of receptors and signalling cascades. The need to recognize multiple peptide signals in self/non-self recognition may have led to the surprising radiation and diversification of RLKs in the plant kingdom.
