Other claims from this paper (11)
- Observation Release of H+ ions and reduction of Fe3+ to Fe2+ are primary responses of T3238FER roots to Fe stress.
- Observation Genotype T3238fer does not respond to Fe stress.
- Observation Fe reduction sites were predominantly in young lateral roots and between the root elongation and maturation zones of the primary root.
- Intervention effect BDPS did not affect H+ ion release or Fe reduction by T3238FER roots.
- Intervention effect BPDS did not decrease Fe uptake below the Fe concentration in the nutrient solution.
- Intervention effect A sevenfold increase in BPDS decreased Fe uptake by the plant threefold.
- Intervention effect Adding Zn decreased the response to Fe stress.
- Observation Iron stress initiates development of lateral roots.
- Mechanism Most Fe is proposed to enter the plant through these roots.
- Mechanism Iron moves through protoxylem and metaxylem of the primary root and then to the shoot top as Fe citrate.
- Mechanism Root environmental factors and genotypes failing to respond to Fe stress are proposed to contribute to Fe deficiency.
