Other claims from this paper (9)
- Intervention effect Maize root Fe-phytosiderophore uptake was greater at acidic pH.
- Intervention effect Maize Fe-phytosiderophore uptake was sensitive to CCCP.
- Intervention effect Heterologous ZmYS1 Fe-phytosiderophore transport was stimulated at acidic pH.
- Intervention effect Heterologous ZmYS1 transport was sensitive to CCCP.
- Mechanism Transport depends on proton cotransport and membrane potential, permitting transport at alkaline pH.
- Intervention effect ZmYS1 complemented the zinc uptake-defective zap1 yeast growth defect.
- Observation ZmYS1 transported phytosiderophore-bound manganese and cadmium at a lower rate.
- Observation ZmYS1 also transported nicotianamine complexes of Ni(II), Fe(II) and Fe(III).
- Mechanism The biochemical properties suggest a novel YS1 role in plant heavy metal homeostasis.
