Function of Golgi Vesicles in Relation to Cell Wall Synthesis in Germinating Petunia Pollen. Iv. Identification of Cellulose in Pollen Tube Walls and Golgi Vesicles by X-Ray Diffraction

The residues of Golgi vesicles and tube walls from germinating Petunia pollen were studied by application of the X-ray diffraction technique after different chemical treatments. In the Golgi vesicles as well as in the tube walls the presence of a cellulose component was demonstrated. This result led to the assumption that the machinery for cellulose synthesis is already present in the Golgi vesicles.
