The distribution of microtubules in differentiating cells of Micrasterias denticulata bréb



The distribution of microtubules in differentiating cells of Micrasterias denticulata bréb



Planta 83(3): 223-236



As an extension of earlier cytophysiological and morphological studies on differentiating cells of Micrasterias denticulata, a fine structural investigation of glutaraldehyde-osmium tetroxide fixed material has been made. Special emphasis has been placed on the distribution of cytoplasmic microtubules and on their possible role in the processes of growth and differentiation. Four distinct systems of microtubules were found: (a) a band in the cortical protoplasm of the isthmus region which surrounds the nucleus; (b) several bands in the cortical protoplasm of the old half cells, with rod-like cross bridges between individual microtubules and between the microtubules and the plasmalemma; (c) clusters of microtubules near the posttelophase nucleus, some separated by "intertubular structures" possibly fibrils; and (d) microtubules in the internal and cortical protoplasm of differentiating half cells.
