Conjugates (Charophyta, Conjugatophyceae) of the Kader bog (Leningrad region, Kurgalsky reserve)
Issues of modern algology (Вопросы современной альгологии), 2021The Kurgalsky Nature Complex Reserve is located in the Kingisepp District of the Leningrad Region, 45 km northwest of Kingisepp. The territory of the reserve includes the Kurgalsky peninsula, as well as the adjacent waters of the Gulf of Finland. The Kader swamp massif is located in the south of the Kurgalsky Peninsula.

Abstract Laboratory crosses between clones of three mating groups of Closterium ehrenbergii Meneghini were studied to ascertain the possibility of gene flow between these two pairs of closely related mating groups of allopatric occurrence. Since only an extremely low percent survival of F1 progenies was obtained along with the morphological abnormality

Abstract. The division rate of Micrasterias torreyi cells grown under continuous illumination first accelerated but soon slowed down, and the cells lost their ability to divide after about 1 month. During the treatment the cells became pale green, the pyrenoids became fewer in number and defects appeared in the chloroplasts.

Journal of Theoretical Biology, 1985
The theories of formal languages and reproducing automata combined with the knowledge about individual development of Micrasterias cells (Chlorophyta, Conjugatophyceae) provide a new approach to embryological problems. The morphogenesis and even speciation of Micrasterias can be simulated with simple methods and, furthermore, simulations of development

Cultivation and inorganic carbon uptake of the rare desmidOocardium stratum(Conjugatophyceae)
Phycologia, 2014The desmid Oocardium stratum is sporadically and exclusively found in active meteogene travertine habitats. The restriction to these peculiar biotopes is probably linked to specific carbon requirements. We studied inorganic carbon (Ci) uptake under controlled laboratory conditions. First, we developed a method for isolating and cultivating O.

Intercellular Communication During Sexual Reproduction of Closterium (Conjugatophyceae)
Journal of Plant Research, 2000were reviewed. In the case of Closterium peracerosum-strigosum-littorale complex, two sex-specific pheromones and their receptors were involved in sexual reproduction. These pheromones were glycoproteins and the expression of corresponding genes was critically regulated by the sex and environmental conditions.
