CC -!- FUNCTION: Extracellular signaling peptide that represses primary root
CC growth rate. Promotes shoot growth and modulates leaf morphology
CC (PubMed:24179096). Regulates systemic nitrogen (N)-demand signaling.
CC Mediates up-regulation of genes involved in N uptake and assimilation
CC pathways (PubMed:25324386). {ECO:0000269|PubMed:24179096,
CC ECO:0000269|PubMed:25324386}.
CC -!- SUBUNIT: Interacts with CEP receptors (e.g. CEPR1 and CEPR2).
CC {ECO:0000250|UniProtKB:Q8L8Y3}.
CC -!- SUBCELLULAR LOCATION: [C-terminally encoded peptide 4]: Secreted,
CC extracellular space, apoplast {ECO:0000250|UniProtKB:O80460}.
CC Note=Accumulates in xylem sap. {ECO:0000250|UniProtKB:O80460}.
CC -!- TISSUE SPECIFICITY: Expressed at low levels in flowers
CC (PubMed:18315543). Present in lateral roots, shoot apical meristem
CC (SAM), flowers and siliques (PubMed:24179095).
CC {ECO:0000269|PubMed:18315543, ECO:0000269|PubMed:24179095}.
CC -!- INDUCTION: Slightly induced in roots by nitrogen and ammonium chloride
CC NH(4)Cl starvation. Accumulates in response to osmotic stress (e.g.
CC mannitol and salt NaCl). {ECO:0000269|PubMed:24179096}.
CC -!- PTM: The mature small signaling peptide is generated by proteolytic
CC processing of the longer precursor. {ECO:0000250|UniProtKB:Q8L8Y3}.
CC -!- SIMILARITY: Belongs to the C-terminally encoded plant signaling peptide
CC (CEP) family. {ECO:0000305}.
