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.
