- Observation Hypoxia perturbs auxin flow and distribution along the root.
- Mechanism Maize ZmPgb1.1 sustains the PIN-mediated auxin maximum during hypoxia.
- Mechanism Maize ZmPgb1.1 sustains an oxidized QC environment during hypoxia.
- Mechanism Activity of redox enzymes oxidizing ascorbate and glutathione maintains the oxidized QC environment.
- Intervention effect Suppressing ZmPgb1.1 compromised the events sustaining QC and root meristem functionality under low oxygen.
