Title
OsPHR2‐OsDIR55 Module Enhances Root Barrier Integrity and Rice Tolerance to Phosphate Deficiency
Wen Duan; Xuemei Li; Baoping Xue; et al. Plant Cell & Environment 2026. doi:10.1111/pce.70686
Other claims from this paper (7)
- Observation Phosphate deficiency induced localized lignification in rice roots.
- Intervention effect OsDIR55 overexpression improved plant performance under low phosphate, including root-to-shoot ratio and biomass.
- Observation Loss-of-function dir55 mutants showed contrasting phenotypes under low phosphate.
- Observation Phosphate deprivation upregulated OsDIR55 expression dependent on OsPHR2.
- Mechanism OsDIR55 maintained cellular phosphate homeostasis under starvation by reinforcing the root apoplastic barrier.
- Observation OsDIR55 disruption caused excessive phosphate accumulation under sufficient phosphate.
- Observation OsDIR55 disruption caused leaf tip necrosis under sufficient phosphate.
