Physiological aspect of mugineic acid, a possible phytosiderophore of graminaceous plants
Abstract
A natural chelator designated mugineic acid (MA) was isolated from the root washings of barley cultivar “Minorimugi”;. The secretion of MA by barley roots occurred in the morning, and was much enhanced under Fe stress. MA enhanced the solubility of Fe(III) between pH 4 and 9. When added to nutrient solutions, MA strongly stimulated the uptake of Fe by “Fe‐inefficient”; rice seedlings. Commonly used chelating agents such as EDTA, EDDHA, citrate, etc. had no stimulative effects. The MA‐mediated Fe uptake proved to be dependent on metabolic energy. These results suggest the possibility of MA functioning as a phytosiderophore for graminaceous plants.

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.
