Other claims from this paper (12)
- Intervention effect Nitrogen deficiency decreased gibberellins and IAA in leaves.
- Intervention effect Nitrogen deficiency increased leaf OPDA, ethylene production and SA biosynthesis.
- Mechanism Altered hormones may contribute to reduced leaf growth and accelerated senescence.
- Mechanism Increased ethylene formation in deficient leaves may be related to ACC, OPDA and ABA changes.
- Intervention effect Nitrogen deficiency increased root/shoot dry weight ratio.
- Intervention effect Nitrogen deficiency altered root system architecture.
- Intervention effect Nitrogen deficiency lowered root cytokinins, jasmonic acid, OPDA and ABA.
- Intervention effect Nitrogen deficiency lowered root ethylene and SA biosynthesis.
- Intervention effect Nitrogen deficiency increased root 5-deoxystrigol.
- Intervention effect Root IAA and gibberellin homeostasis were maintained under nitrogen deficiency.
- Mechanism Unchanged root IAA involved increased leaf-to-root IAA transport.
- Mechanism The authors suggest divergent leaf and root hormones contribute to improved N use and acquisition and deficiency tolerance.
