• Crown-gall tumor tissue obtained from potato discs inoculated with virulent strains of Agrobacterium tumefaciens contained higher concentrations of K^+, Mg^<2+> and Ca^<2+> than the corresponding normal tissue. These tumors also contained higher concentrations of these cations than normal tissue inoculated with an avirulent strain of Agrobacterium tumefaciens, or than normal tissue adjacent to the crown-gall tumors on the same potato disc. The concentration of these cations remained significantly higher than control tissue regardless of the tumor age. 2,4-Dinitrophenol and myo-inositol, while affecting the concentration of Ca^<2+> in these tissues, had no effect on the Mg^<2+> and K^+ concentrations. These results suggest increased concentrations of certain cations may be a specific property of crown-gall tumors.
