CEPR1 orthologues in barley, maize, and rice restore wild-type phenotypes in Arabidopsis complementation assays, and CEPR1 knockout in barley alters seminal root angle.
- Why it matters: Root molecular control under water and nitrogen limitation is poorly understood in cereals, limiting agronomic progress despite the CEP family’s established roles in model dicots.
- What they did: The review integrates CEP biology with cereal root architecture, citing Arabidopsis/Medicago work on CEPD/CEPR1 signalling, auxin–cytokinin lateral root angle control, and AUX/IAA stabilization under osmotic stress.
- The result: Barley CEPR1 knockout confirms effects on seminal root angle but reveals a fecundity defect, while wheat TaCEP15 modulates primary root length and drought tolerance via a distinct receptor pathway.
