Closterium - Wikipedia
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 - an overview | ScienceDirect Topics
The genus Closterium, which is the closest unicellular relative to land plants, is the best-characterized charophycean green alga with respect to the process of sexual reproduction. In two representative heterothallic species, the steps and methods of …

2018年7月11日 · The genus Closterium, belonging to the Zygnematophyceae, is the best-characterized charophycean alga in terms of sexual reproduction, since Ichimura (1971) developed an efficient method for inducing sexual reproduction.
Closterium Nitzsch ex Ralfs - Connecticut College
Closterium cells are crescent-shaped or elongate and lack spines. Some are quite straight and needle-like, while others are much broader with curved ends. The ends of the cell are usually tapered and may be pointed or rounded.
Freshwater Algae: Desmids. Introduction to Desmids with ...
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.

Closterium archerianum. Markedly curved species with striate cell wall (striae shown only near median suture). Closterium is collected most often from the benthos or periphyton of acidic, oligotrophic lakes and ponds; it occurs more rarely in alkaline, eutrophic environments.

Monophyly of the genus Closterium and the order Desmidiales (Charophyceae, Chlorophyta) inferred from nuclear small subunit rDNA data.
Closterium | genus of green algae | Britannica
green algae, members of the division Chlorophyta, comprising between 9,000 and 12,000 species. The photosynthetic pigments (chlorophylls a and b, carotene, and xanthophyll) are in the same proportions as those in higher plants.
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 exhibits gliding locomotory behavior, mediated by the forceful extrusion of mucilage from one pole of the cell that causes the cell to glide in the opposite direction (Domozych et al., 1993).
