Phylogenetic Relationships in Interfilum and Klebsormidium (Klebsormidiophyceae, Streptophyta)
Molecular Phylogenetics and Evolution, 2011 Members of the genus Klebsormidium have cosmopolitan distribution and occur in a very wide range of freshwater and terrestrial habitats. Due to its simple filamentous morphology, this genus represents a taxonomically and systematically complex taxon in which phylogenetic relationships are still poorly understood.

Snow Ball Earth and the Split of Streptophyta and Chlorophyta
Trends in Plant Science, 2013About 700 million years ago (Mya), the ancestor of all green plants evolved into two major groups: the Chlorophyta (many green algae) and the Streptophyta (some green algae and land plants = embryophytes). Both groups are separated by several morphological, physiological, and molecular characteristics, including different photorespiration pathways. The

Green Algae (Chlorophyta and Streptophyta) in Rivers
2016The green algae represent one of the most diverse and abundant algal lineages in river systems around the world, and their evolutionary diversification led to two major lineages, the Chlorophyta and Streptophyta (with the latter including the land plants).

Phylogeny and Classification of Zygnematophyceae (Streptophyta): Current State of Affairs. [PDF]
Fottea, 2008 Conjugates (Zygnematophyceae) represent the most species-rich (ca. 4000 spp) algal lineage within the Streptophyta. Studies using various molecular markers have placed the class as one of the crown groups in Streptophyta and even suggested a close relationship between the zygnematophycean algae and land plants.

The Role of Microsatellites in Streptophyta Gene Evolution
Journal of Molecular Evolution, 2017Microsatellites form hotspot regions for recombination. In this research, we investigated whether genic microsatellites can be responsible for generating new genes by enhancing crossover between gene containing microsatellites and other genomic regions. We tested our hypothesis on 33,531 UniGene entries containing microsatellites.

The System of Contractile Vacuoles in the Green Alga Mesostigma viride (Streptophyta)
Protist, 2009The contractile vacuole (CV) is an osmoregulatory organelle which is found in many protists. We have investigated the structure and function of the CV in the green alga Mesostigma viride by light (video) and serial section electron microscopy. Mesostigma is the only known flagellate streptophyte (charophycean green algae and land plants) and therefore ...

Penium amplificatum status nova (Desmidiales, Streptophyta)
Phytotaxa, 2012From extensive field studies in the Dutch province of Drenthe and comparative literature research it appeared that Penium spirostriolatum var. amplificatum differs from the nominate variety of Penium spirostriolatum not only by its capitate cell ends but also by coarser and more spiralized ridges on the cell wall and by distinctly different ecological ...

Brefeldin A affects the system of contractile vacuoles in Mesostigma viride (Streptophyta)
Algological Studies, 2015Brefeldin A was used to disrupt the contractile vacuoles (CVs) of the streptophyte green flagellate Mesostigma viride. Treatment of M. viride with BFA caused enlarged CVs, as well as a decrease in the number of CVs, and finally the cells burst. In addition, BFA treated cells revealed the typical changes in Golgi structure (decrease in number of ...

Chara dominii Vilh. (Streptophyta: Charales): a New Species in the Flora of Russia
Inland Water Biology, 2018Chara dominii Vilh. is a new species in the flora in Russia. It has been found in Altai krai, Astrakhan oblast, and the Republic of Kalmykia. These findings change the concept of the northern border of the species living range considerably, as practically all C. dominii finds reported up to now were made in Central Asia.
