abstract：:When spores of Dictyostelium discoideum matured through normal development were stained with rhodamine-phalloidin, rod-shaped fluorescence was found across the nucleus and in the cytoplasm. Electron micrographs of the rod shape showed that it consisted of long and straight fibers 12 nm in diameter. In contrast, a conv...
