  Kransþörungar (Charophyta) - MavicaNET   (Site not responding. Last check: 2007-11-05)
Charophyta are freshwater plants and generally grow anchored to the substratum by rhizoids with a shoot extending upward.
Charophyta reproductive structures develop at these nodes and are, along with the biflagellate sperm produced in the male gametangium, quite similar to those of mosses.
Stoneworts are a small group of terrestrial or freshwater simple, green algae, of the family Charophyta.

 Charophyta - MicrobeWiki
Charophyta are commonly known as stoneworts or brittleworts.
It was commonly believed that Charophyta were related to embryophytes (land plants).
Some of the characteristics between Charophyta and land plants are: homologous chloroplasts, as welll as similarites in mitosis, sperm ultrastructure, cell wall composition, peroxisomes, and genetic data.

Nyberg and Saranpaa noted that the cytoplasmic structure of internodal and cortical cells is consistent across Charophyta species.
Charophyta can reproduce asexually or sexually; sexual reproduction is the primary method.
Some species of Charophyta are are considered to be in need of protection.

The corresponding stem clades are Chlorophyta (Chlamydomonas > Quercus) and Charophyta (Quercus > Chlamydomonas).
The Charophyta are the other lineage of green algae, the group which includes the land plants.
The Charophyta have recently been referred to as the Streptophyta, but the reasons given for this change in nomenclature are probably insufficient.

 Lewandowski, Jeffrey D.* and Charles F. Delwiche.   (Site not responding. Last check: 2007-11-05)
Relationships within the Charophyta have previously been based on morphology and inferred through phylogenetic analyses of molecular data that include ribosomal DNA and several genes from the chloroplast and mitochondrial genomes.
We are attempting to isolate and sequence actin-coding regions from representative members of the Charophyta.
Hence, in addition to being potentially useful for resolving organismal relationships, the evolution of the actin protein itself is intrinsic to the study of morphological evolution and development within green plants.

These similarities have led some scientists to identify the charophytes as ancestors of the mosses.

Stoneworts have a requirement for calcium carbonate, consequently the greatest concentrations and diversity of these species are found on the coastal sand dunes and in pools situated on basic soils.
Stoneworts, or charophytes, are a group of complex algae that are usually included in the recording activities of botanical societies because they superficially resemble vascular plants more than they do other groups of algae.

While there are a disproportionately few "large" algae in the Division Chlorophyta most of the macroscopic algae belong to one of three Divisions: the Division Phaeophyta; Division Rhodophyta; and Division Charophyta.
While there is no dispute about the organisms in the first two divisions being algae, some taxonomists have questioned the validity of placing the Charophyta with the algae.
The few species of the division Charophyta are exclusively freshwater.

The lack of this latter feature is normally considered the major characteristic which separates algae from other "plants".
There are only four genera of Charophyta occurring in North America.
They are generally found in freshwater, anchored by rhizoids in sandy or muddy substrates.

Title : RUI: Molecular and Morphological Phylogenetic Systematics of Extant and Fossil Characeae (Charophyta) Abstract : 9407606 McCourt In an intriguing and challenging application of both molecular and morphological data to a problem in phylogeny, Professor Richard McCourt at DePaul University will be studying the algal group known as stoneworts, the Charophyta.
Representatives of all seven genera of living members of the group will be analyzed for a number of genes by nucleotide sequencing methods, to acquire data on mutational differences among the species.
As well, their fossil record provides an opportunity to calibrate rates of molecular change in genes.
