Other claims from this paper (12)
- Observation OsMADS57 was abundant in root stele xylem parenchyma and induced by nitrate.
- Intervention effect OsMADS57 mutation reduced xylem nitrate loading by 31%.
- Intervention effect OsMADS57 overexpression increased xylem loading twofold.
- Observation Shoot-root 15N ratios were 40% lower in mutants.
- Observation Shoot-root 15N ratios were 76% higher in overexpression lines.
- Observation OsMADS57 mutation did not affect root nitrate uptake.
- Observation Three additional NRT2 genes showed lower expression after 60 minutes.
- Observation Four NRT2 genes had higher expression in overexpression lines.
- Observation OsMADS57 bound the CArG motif within the OsNRT2.3a promoter.
- Observation Seminal root elongation was inhibited in osmads57 mutants.
- Association Mutant root inhibition may be associated with higher auxin levels and transport.
- Mechanism OsMADS57 may regulate nitrate translocation via OsNRT2.3a.
