10-3-10-2M EDTA significantly decreased K uptake. P was released into the culture medium from roots treated with EDTA, indicating the disintegration of cold TCA-insoluble organic P. Nucleotides, nucleosides, cytosine, adenine and guanine were detected in the medium. Inhibition of K uptake accompanied the disappearance of RNA particles in young root hairs near the root cap.
