PCEP5_ARATH | function | Extracellular signaling peptide that represses plant growth rate. Regulates shoot gravitropic responses (PubMed:24179095). Represses primary root length and lateral root initiation, probably by repressing the CEP receptor CEPR1 (PubMed:24179096, PubMed:27296247). Regulates systemic nitrogen (N)-demand signaling. Mediates up-regulation of genes involved in N uptake and assimilation pathways (PubMed:25324386). |
PCEP5_ARATH | similarity | Belongs to the C-terminally encoded plant signaling peptide (CEP) family. |
PCEP5_ARATH | subcellular location | Accumulates in xylem sap. |
PCEP5_ARATH | tissue specificity | Mostly expressed in roots, and, at lower levels, in stems, leaves and flowers (PubMed:18315543, PubMed:24179095). Present in lateral root primordia (especially in vasculature and in the basal meristem) (PubMed:24179095, PubMed:27296247). Predominantly expressed in the phloem pole-associated pericycle (PPP) cells, and, to a lower extent, in the adjacent phloem (PubMed:27296247). Observed in lateral roots (especially in vasculature), root-hypocotyl junction, leaves, inflorescence stems and flowers (PubMed:24179095). |
