Other claims from this paper (10)
- Observation AtNRAMP3 was expressed in vascular bundles of roots, stems, and leaves under sufficient iron.
- Intervention effect Iron starvation upregulated AtNRAMP3 promoter activity without altering its expression pattern.
- Intervention effect AtNRAMP3 overexpression did not change plant metal content under iron sufficient conditions.
- Intervention effect AtNRAMP3 disruption did not change plant metal content under iron sufficient conditions.
- Intervention effect Under iron starvation, AtNRAMP3 disruption increased manganese accumulation in roots.
- Intervention effect Under iron starvation, AtNRAMP3 disruption increased zinc accumulation in roots.
- Intervention effect AtNRAMP3 overexpression downregulated manganese accumulation under iron starvation.
- Intervention effect AtNRAMP3 overexpression downregulated IRT1 expression.
- Intervention effect AtNRAMP3 overexpression downregulated FRO2 expression.
- Observation AtNRAMP3 protein localized to the vacuolar membrane.
