Other claims from this paper (9)
- Method / resource PETIS and PMPS visualized nitrogen and water translocation in rice plants in real time.
- Observation Root-supplied ammonium reached the discrimination center within 2 minutes under normal conditions.
- Intervention effect Nitrogen deficiency enhanced 13N translocation to the discrimination center.
- Intervention effect Darkness suppressed 13N translocation to the discrimination center to 40% of control levels.
- Intervention effect Darkness completely stopped water flow from roots to the discrimination center.
- Intervention effect Abscisic acid doubled 13N translocation to the discrimination center.
- Intervention effect Abscisic acid decreased 13N translocation to leaves to 40% of control levels.
- Intervention effect Nitrate pretreatment increased root-to-discrimination-center 13N translocation to five times control levels.
- Mechanism The authors infer ammonium assimilation depends passively on water flow and actively on ammonium transporters or glutamine synthetases.
