Other claims from this paper (8)
- Intervention effect PNN-mediated NO increased lateral root initiation in cultivar Nanguang.
- Intervention effect PNN-mediated NO increased ammonium and nitrate transporter levels in cultivar Nanguang.
- Intervention effect PNN-mediated NO had no such effect on ammonium and nitrate transporter levels in cultivar Elio.
- Intervention effect NH4+ plus sodium nitroprusside markedly induced lateral root initiation relative to NH4+ alone in rice.
- Intervention effect NH4+ plus sodium nitroprusside markedly induced inorganic N influx into rice roots relative to NH4+ alone.
- Intervention effect cPTIO considerably inhibited lateral root initiation when applied in addition to PNN.
- Intervention effect Tungstate, an NR inhibitor, considerably inhibited lateral root initiation when applied in addition to PNN.
- Mechanism The authors suggest that NO generated by the NR pathway improves N acquisition capacity in rice by increasing lateral root initiation and inorganic N uptake.
