Other claims from this paper (6)
- Intervention effect Nitrogen deficiency stimulates iron export from barley source leaves.
- Intervention effect Nitrogen deficiency partially alleviates Fe deficiency-induced chlorosis in barley.
- Intervention effect Shading and nitrogen deficiency enhance NICOTIANAMINE SYNTHASE2 gene expression and soluble Fe pools in barley source leaves.
- Intervention effect Shading and nitrogen deficiency enhance phytosiderophore and citrate concentrations in barley source leaves rather than nicotianamine concentrations.
- Association Iron mobilisation within senescing barley leaves is independent of a concomitant nitrogen sink in young leaves.
- Mechanism Phytosiderophores enhance iron solubility in senescing barley source leaves, favouring subsequent iron retranslocation.
