Closterium is a diverse genus consisting of solitary cells, each made of two identical halves called semicells. Usually they are microscopic, but the largest can become easily visible to the naked eye.

Closterium is the best characterized charophyte in terms of processes of sexual reproduction biochemically, physiologically, and molecular biologically [61,62]. Transformation systems have been established in the C. psl. complex using particle bombardment [63] and square-pulse electroporation [64].

Jul 11, 2018 · Closterium occupies a key phylogenetic position as an ancestor of land plants and is the best-characterized Charophycean alga in terms of the process of sexual reproduction.

Here we review knowledge on the intercellular communication and mating type determination for successful sexual reproduction in Closterium. Using genomic information and transgenic techniques, the genus could be a model organism to study the mechanisms and evolution of sexual reproduction in streptophytes.

Closterium is a placoderm desmid because the cell walls have pores to secrete mucilage, even though the cells are only slightly contricted in the middle compared to other placoderms.

Closterium is a common desmid in most freshwater habitats. It lacks the isthmus of the general description above but has at the extreme ends of each semi-cell a small spherical vacuole in which varying numbers of tiny particles can be seen in constant agitated motion.

Here we review knowledge on the intercellular communication and mating type determination for successful sexual reproduction in Closterium. Using genomic information and transgenic techniques, the genus could be a model organism to study the mechanisms and evolution of sexual reproduction in streptophytes.

Approximately 140 species of Closterium have been described, with 88 found in North America. Closterium is most common in the benthic or periphytic communities of acidic, oligotropic lakes and ponds.

Jan 1, 2014 · The genus Closterium is the best characterized charophycean charophycean green alga with respect to the process of sexual reproduction. Two sex...

Closterium is collected most often from the benthos or periphyton of acidic, oligotrophic lakes and ponds; it occurs more rarely in alkaline, eutrophic environments. C. aciculare and C. acutum are planktonic in eutrophic waters, often among cyanobacterial blooms.
