Abstract
Fe-deficient (chlorotic) Hawkeye soybean plants (Glycine max) develop a greater capacity to absorb Fe than Fe-sufficient plants. Radioautograms of electrophoretically separated components of the stem exudate showed Fe59 to be located largely as an iron malate complex. Mn, Zn, Cu, Ca, Mg, and K + Rb ions interfered with the uptake-transport of Fe by chlorotic plants. Zn was the strongest interfering ion. Radioautograms of electrophoretically separated components of stem exudate showed that Zn65 stopped Fe59 translocation but Zn did not occur in the malate complex where Fe is usually found.This publication has 4 references indexed in Scilit:
