Studies on the fine structural changes accompanying xylem differentiation in wheat coleoptile have indicated that the microtubules are concerned with the inception of a regular wall thickening pattern, and later with wall deposition at the thickening site. The endoplasmic reticulum is situated characteristically in continuous profiles between the thickenings. Radioautographic studies at the electron microscope level using labelled glucoses have shown that the endoplasmic reticulum, golgi bodies and the cytoplasm near the microtubules were often labelled during deposition into nearby thickenings of radioactive materials derived from the tritiated glucoses. Incorporation into the wall occurred..
