The initial and subsequent distribution of 22 Na, 43 K, 86 Rb, 134 Cs, 32 P, 35 S, 45 Ca, 65 Zn and 85 Sr in bean plants, following leaf and root uptake was studied under controlled environmental conditions. Autoradiographic and counting methods reveal vascular connections between leaves and roots and two patterns of distribution in the leaves following root uptake are reported. Distribution following treatment of specific parts of the leaves or roots points to a morphological unity in the bean plant. A possible circulation pattern for some ions is discussed.
