Article Synopsis
- Iron (Fe) and manganese (Mn) are crucial for plant growth, and in Arabidopsis thaliana, their uptake is primarily managed by high affinity transporters IRT1 and NRAMP1.
- Mutant plants lacking both transporters displayed severe Fe deficiency symptoms, even when Fe was present in adequate amounts, indicating the importance of these transporters for Fe uptake.
- The study revealed that NRAMP1 is essential for Fe transport and works alongside IRT1, providing the first evidence of a low affinity Fe uptake system in plants, while also suggesting a role in Mn uptake.
Zinc (Zn) is essential for the optimal growth of plants but is toxic if present in excess, so Zn homeostasis needs to be finely tuned. Understanding Zn homeostasis mechanisms in plants will help in the development of innovative approaches for the phytoremediation of Zn-contaminated sites. In this study, Zn tolerance quantitative trait loci (QTL) were identified by analyzing differences in the Bay-0 and Shahdara accessions of Arabidopsis thaliana.

Root and shoot growth as well as Zn content were determined for 27 A. thaliana accessions grown in vitro in presence of Zn concentrations ranging from 1 to 250 µm.

In order to unravel the molecular basis of zinc (Zn) tolerance in the Zn hyper-accumulating plant Arabidopsis halleri ssp. halleri, we carried out a functional screening of an A.
