| Description | Precursor of CEP1 (PCEP1) [Cleaved into- C-terminally encoded peptide 1 (CEP1)] |
| Organism | Arabidopsis thaliana |
| Txonomy | Eukaryota; Viridiplantae; Streptophyta; Streptophytina; Embryophyta; Tracheophyta; Euphyllophyta; Spermatophyta; Magnoliopsida; Mesangiospermae; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis; Arabidopsis thaliana (Mouse-ear cress) |
| Subcellular Location | [C-terminally encoded peptide 1]- Secreted; extracellular space; apoplast |
| Developmental Stage | In young seedlings; only observed in lateral root primordia; first in the core region at stage VI; in which cells of outer layer 2 undergo a periclinal division; creating a new internal layer (PubMed- |
| Similarity | Belongs to the C-terminally encoded plant signaling peptide (CEP) family. |
| Tissue Specificity | Mainly expressed in the lateral root primordia (PubMed-18315543). Also present in the shoot apical meristem (SAM) (PubMed-18315543; PubMed-24179095). Detected in the primary root apical meristem; at t |
| Post Translational Modification | The mature small signaling peptide is generated by proteolytic processing of the longer precursor. |
| Function | Extracellular signaling peptide that represses; in a dose-dependent manner; primary root growth rate and lateral root elongation by inhibiting both cell division in meristems and cell growth in elongation zones. Prevents also slightly growth of above-ground parts |
