In plants and animals, small peptide ligands that signal incell-cell communication have been suggested to be a crucialcomponent of development. A bioassay of single-cell transdifferentationdemonstrates that a dodecapeptide with two hydroxyproline residuesis the functional product of genes from the CLE family, whichincludes CLAVATA3 in Arabidopsis. The dodecapeptide suppressesxylem cell development at a concentration of 1011 M andpromotes cell division. An application, corresponding to all26 Arabidopsis CLE protein family members, of synthetic dodecapeptidesreveals two counteracting signaling pathways involved in stemcell fate.
