Function

function

LRR receptor kinase involved in the regulation of root growth and root nodule organogenesis (PubMed:16240175, PubMed:16941903, PubMed:22399647).
Involved in long distance nodulation signaling events (Probable) (PubMed:22399647).
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) (PubMed:27135324).
Acts from shoot to root to control AON (PubMed:27135324, PubMed:28592666).
Interacts with CLE12 and CLE13 signaling to control nodule numbers (PubMed:22168914).
Required for the modulation of shoot-to-root auxin transport in response to altered nitrogen tissue concentrations and in the absence of rhizobia (PubMed:22399647).
Shoot-to-root auxin transport influences lateral root density and length (PubMed:22399647).
Involved in the regulation of root colonization by arbuscular mycorrhizal (AM) fungi (PubMed:16941903, PubMed:31477892).
Interacts with CLE33 and CL53 signaling to repress strigolactone biosynthetic genes and strigolactone content in the roots, and consequently reduces the promotion of further colonization by AM fungi (PubMed:31477892).
