Soybean exudates contain iron compounds which can be separated electrophoretically into anodic bands and eluted with water. Chromatography of the water extracts separated iron from chelating agents which were identified as malic acid and malonic acid. Hence organic acids seem to function in the translocation of iron in plants.
