[Studies on the distribution of actin during meiotic prophase I of Nicotiana rustica L].
The Pollen Mother Cells of Nicotiana Rustica L. were studied using the techniques of immunofluorescence microscopy and protein A-colloidal gold IEM. Immunofluorescence microscopy indicates the presence of actin in both nuclei and cytoplasm. IEM observation shows that gold particles are present in cytoplasm, chromatin and cytomictic channels. These results indicate that actin has some relation with chromatin condensing at synizesis. Moreover, actin may also play an important role in cytomixis.
