Raven, Janet I. Sprent] Labelled iron (applied as 55FeCl3) moves rapidly from the soil to the shoots and stem nodules of S. rostrata. Time-course experiments are described that investigate the movement of iron through different plant parts, detailing the route of iron translocation. The results show that iron moves first to the mature leaves and is subsequently translocated to the vegetative buds and stem nodules. Phloem girdling the stem nodules almost completely stops the movement of labelled iron into the nodules. We conclude that iron is supplied to stem nodules in the phloem; these results support other work suggesting there is no inward xylem flow into legume nodules, which probably receive almost all nutrients and most of their water via phloemmediated transport. © Oxford University Press Research Papers nationallicence Translocation nationallicence nutrient nationallicence Fe nationallicence iron nationallicence stem nodules nationallicence legume nationallicence nitrogen fixation nationallicence Parsons Richard Department of Biological Sciences, University of Dundee, Dundee DD14HN, UK aut Raven John A.
