Mitotic peaks and mitotic time in the desmidiaceae
Archiv f�r Mikrobiologie, 1965In a day having 12 hours each of light and darkness mitotic periodicity has been found in Closterium siliqua and Cosmarium botrytis, there being a peak in the dark period. C. botrytis also has a low back-ground mitotic level at other times. The mitotic time was calculated in Closterium siliqua as follows:

SPECTRIN‐LIKE PROTEINS IN GREEN ALGAE (DESMIDIACEAE)
Cell Biology International, 1999Immunochemical detection of actin as well as spectrin‐like proteins have been carried out in the green algae Micrasterias denticulata, Closterium lunula, and Euastrum oblongum. In these algae, actin is detected on Western blots at 43kDa with antibodies to actin from higher plant and animal origin.
