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.

New records of Cosmarium (Desmidiaceae) to Brazil
Phytotaxa, 2011This study presents 14 specific and infra-specific pioneer citations of the genus Cosmarium for the Brazilian desmid flora. Sixty-three samples of planktonic and periphytic material studied were collected in three Environmental Protection Areas (Rio Capivara, Lagoas de Guarajuba and Litoral Norte), located in Bahia State, northeastern Brazil, during ...

SCANNING ELECTRON MICROSCOPY: A NEW APPROACH TO THE DESMIDIACEAE
Journal of Phycology, 1969SUMMARY A camera lucida drawing, light and SEM micro‐graphs of Cosmarium botrytis are contrasted with the intent of showing the advantages of SEM in systematic and morphological investigations. Several developmental questions amenable to an approach with SEM have arisen.

Issues of modern algology (Вопросы современной альгологии), 2022
The article deals with the problems of taxonomy of desmid algae (Desmidiaceae). An analysis of the literature devoted to studies of cell morphogenesis and the role of cellular structures in the formation of daughter semicells was carried out. It is shown that the traits of desmidian algae cells, such as the length and number of processes, the degree of

Desmids (Chlorophyta, Desmidiaceae) from Thale Noi (Thailand)
Nordic Journal of Botany, 2000The desmid flora of laguna Thale Noi, a large freshwater lake in the south‐eastern part of Thailand, appeared to be characterized by a high portion of non‐cosmopolitan taxa. Next to a series of pantropical species, quite a lot of Indo‐Malaysian/North Australian flora elements were encountered.

Remarkable desmids (Desmidiaceae, Charophyta) from Sardinia, Italy
Nordic Journal of Botany, 2007A number of benthic microfauna samples collected in Sardinia in the 1970s, and screened for the occurrence of microalgae in the 1990s, revealed some remarkable desmid species. Most of these species could not be found in a series of samples collected in 2006.
