The soybean NRAMP homologue, GmDMT1, is a symbiotic divalent metal transporter capable of ferrous iron transport
Open accessAbstract
Summary: Iron is an important nutrient in N 2‐fixing legume root nodules. Iron supplied to the nodule is used by the plant for the synthesis of leghemoglobin, while in the bacteroid fraction, it is used as an essential cofactor for the bacterial N 2‐fixing enzyme, nitrogenase, and iron‐containing proteins of the electron transport chain. The supply of iron to the bacteroids requires initial transport across the plant‐derived peribacteroid membrane, which physically separates bacteroids from the infected plant cell cytosol. In this study, we have identified Glycine max divalent metal transporter 1 (GmDmt1), a soybean homologue of the NRAMP/Dmt1 family of divalent metal ion transporters. GmDmt1 shows enhanced expression in soybean root nodules and is most highly expressed at the onset of nitrogen fixation in developing nodules. Antibodies raised against a partial fragment of GmDmt1 confirmed its presence on the peribacteroid membrane (PBM) of soybean root nodules. GmDmt1 was able to both rescue growth and enhance 55 Fe(II) uptake in the ferrous iron transport deficient yeast strain (fet3fet4). The results indicate that GmDmt1 is a nodule‐enhanced transporter capable of ferrous iron transport across the PBM of soybean root nodules. Its role in nodule iron homeostasis to support bacterial nitrogen fixation is discussed.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
