e0“Rice (Oryza sativa) uses ammonium as its main N source. Here we show that ammonium supply restricts rice root elongation and induces a helical growth pattern”
Title

Other claims from this paper (7)
- Intervention effect Ammonium induces helical root growth in rice.
- Mechanism Root acidification from ammonium uptake is attributed as the cause of rice helical growth.
- Mechanism Ammonium-induced low pH triggers asymmetric auxin distribution in rice root tips through altered signaling.
- Intervention effect Blocking auxin signaling inhibited the rice helical root response.
- Intervention effect Ammonium treatment did not activate the helical root response in Arabidopsis.
- Mechanism Arabidopsis root acidification protonates indole-3-acetic acid.
- Mechanism Arabidopsis root acidification dampens intracellular auxin signaling needed for root growth.
