Activity

  • Function:  Signaling peptide involved in the regulation of nodulation.
  • Mechanism:  Moves from root to shoot to function with the receptor kinase SUNN, in a signaling pathway that plays roles during cellular differentiation, both at the onset of nodulation, and later during nodule meristem development and subsequent homeostasis. Interacts with SUNN signaling to control nodule numbers. SUNN is involved in the autoregulation of nodulation (AON), a long distance systemic signaling from root to shoot and back again, which allows legumes to limit the number of root nodules formed based on available nitrogen and previous rhizobial colonization (Probable).
