Other claims from this paper (6)

Observation Fe was allocated to leaf veins after one day in Fe-WEHS-fed plants.
Observation After five days, Fe had transferred into interveinal cells.
Association Fe redistribution in Fe-WEHS plants was associated with upregulation of FRO, IRT1 and NRAMP.
Observation FRO and IRT1 transcripts localized next to midveins.
Observation NRAMP transcripts localized in the interveinal area.
Association Fe appeared to be used more efficiently when chelated to WEHS than PS.

Other claims from this paper (7)

Intervention effect Iron deficiency sharply decreased root Fe concentration in maize.
Association Leaf Fe concentration did not reflect Fe supply despite low total Fe in chlorotic maize leaves.
Intervention effect Fe deficiency also changed concentrations of other nutrients, with larger changes in microelements.
Association Leaf Mn and Zn concentrations depended on the degree of Fe deficiency.
Observation Cu transport to leaves appeared hampered, with most Cu retained in roots.
Intervention effect Chlorotic maize had a smaller root portion of Fe, Mn and Ca than controls.
