SUMMARY Radioautographs by light and electron microscopy of callus cells of green ash ( Fraxinus pennsylvanica Marsh.) that had been fed low levels of the growth factor 3 H myo ‐inositol indicated an almost exclusive incorporation of the label into the cytoplasmic constituents. These results contrast with those from most other studies of incorporation in higher plants. The incorporation here of myo ‐inositol suggests that its prime function is the synthesis of cytoplasmic membrane systems of the cell rather than in the polysaccharide component of the primary wall.
