Cyanophora Paradoxa
''Cyanophora paradoxa'' is a freshwater species of Glaucophyte that is used as a model organism. ''C. paradoxa'' has two cyanelles or chloroplasts where photosynthesis occurs. Cyanelles are unusual organelles in that they retain a rudimentary peptidoglycan wall. The cyanelle genome of ''C. paradoxa'' strain LB 555 was sequenced and published in 1995. The nuclear genome was also sequenced and published in 2012. Description ''Cyanophora paradoxa'' is a unicellular organism with two flagella A flagellum (; : flagella) (Latin for 'whip' or 'scourge') is a hair-like appendage that protrudes from certain plant and animal sperm cells, from fungal spores ( zoospores), and from a wide range of microorganisms to provide motility. Many pr ..., attached near the tip of the cell. The cell body is about 7-15 μm long by 3-6 μm wide; it is roughly ovoid (egg-shaped) in shape, and is covered in ridges that outline triangular or crescent-shaped "fenestrations". Each cell generally has one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glaucophyte
The glaucophytes, also known as glaucocystophytes or glaucocystids, are a small group of unicellular algae found in freshwater and moist terrestrial environments, less common today than they were during the Proterozoic. The stated number of species in the group varies from about 14 to 26. Together with the red algae (Rhodophyta) and the green algae plus land plants ( Viridiplantae or Chloroplastida), they form the Archaeplastida. The glaucophytes are of interest to biologists studying the evolution of chloroplasts as they may be similar to the original algal type that led to the red algae and green plants, i.e. glaucophytes may be basal Archaeplastida. Unlike red and green algae, glaucophytes only have asexual reproduction. Reproduction Unlike red and green algae, glaucophytes only have asexual reproduction. Glaucophytes reproduce exclusively through asexual means. They undergo open mitosis without centrioles, a trait shared with other basal eukaryotes. Reproductive modes ...

Cyanophora Cuspidata
''Cyanophora cuspidata'' is a species of algae classified as a glaucophyte. It was first identified as a distinct species in 2014, from a strain isolated from Erlangen, Germany in 1967. Morphology Cells of ''C. cuspidata'' have been reported to be "obovoid to ellipsoidal" in shape, with sizes ranging from 5-12 μm in length and 2-5 μm in width. A distinct tapered "tail" has been reported at the tips of cells, which is unique among ''Cyanophora''. Cells have only 1-2 plastids. As with other ''Cyanophora'' species, no cell wall is present. Use as a model organism ''Cyanophora'' is notable as the only glaucophyte taxon known to possess a flagellum for the entirety of its life cycle. The flagella of ''C. cuspidata'' has been studied as a method to more accurately place glaucophytes within eukaryote phylogeny A phylogenetic tree or phylogeny is a graphical representation which shows the evolutionary history between a set of species or Taxon, taxa during a specific time.Fels ...

Cyanophora Kugrensii
''Cyanophora kugrensii'' is an algal species classified as a glaucophyte. It was first described as a distinct species in 2014, identified from a strain collected in 1987 in Jōsō, Ibaraki Prefecture, Japan. Morphology Cells of ''C. kugrensii'' range in size from 5 to 15 μm in length and from 2 to 6 μm in width, with a shape described as "elongate-ovoid". ''C. kugrensii'' lacks the pointed posterior found in its close relative ''Cyanophora cuspidata'', containing instead a rounded end. Cells contain 1-2 plastids A plastid is a membrane-bound organelle found in the cells of plants, algae, and some other eukaryotic organisms. Plastids are considered to be intracellular endosymbiotic cyanobacteria. Examples of plastids include chloroplasts (used for photo ....

Cyanophora Sudae
''Cyanophora sudae'' is a species of algae classified as a glaucophyte. It was first described as a distinct species in 2014, identified from a strain collected in Ibaraki, Japan. It was named after the collector of the first strain, Dr. Soichiro Suda of University of the Ryukyus. Morphology ''Cyanophora sudae'' cells have been described as being broad and bean-shaped, with sizes ranging from 9-12 μm in length and 4-9 μm in width. Cells have anywhere between 2-8 plastids, although they generally have four. Honeycomb-shaped patterns have been observed on the surface of ''C. sudae'' cells when viewed via SEM microscopy. Phylogeny Within ''Cyanophora'', ''C. sudae'' is considered to be most closely related to ''Cyanophora biloba'', on the basis of the similarity of plastid and mitochondrial DNA Mitochondrial DNA (mtDNA and mDNA) is the DNA located in the mitochondrion, mitochondria organelles in a eukaryotic cell that converts chemical energy from food into adenosine ...

Cyanelle
A plastid is a membrane-bound organelle found in the cells of plants, algae, and some other eukaryotic organisms. Plastids are considered to be intracellular endosymbiotic cyanobacteria. Examples of plastids include chloroplasts (used for photosynthesis); chromoplasts (used for synthesis and storage of pigments); leucoplasts (non-pigmented plastids, some of which can differentiate); and apicoplasts (non-photosynthetic plastids of apicomplexa derived from secondary endosymbiosis). A permanent primary endosymbiosis event occurred about 1.5 billion years ago in the Archaeplastida cladeland plants, red algae, green algae and glaucophytesprobably with a cyanobiont, a symbiotic cyanobacteria related to the genus '' Gloeomargarita''. Another primary endosymbiosis event occurred later, between 140 and 90 million years ago, in the photosynthetic plastids ''Paulinella'' amoeboids of the cyanobacteria genera ''Prochlorococcus'' and '' Synechococcus'', or the "PS-clade".

Model Organism
A model organism is a non-human species that is extensively studied to understand particular biological phenomena, with the expectation that discoveries made in the model organism will provide insight into the workings of other organisms. Model organisms are widely used to research human disease when human experimentation would be unfeasible or unethical. This strategy is made possible by the common descent of all living organisms, and the conservation of metabolic and developmental pathways and genetic material over the course of evolution. Research using animal models has been central to most of the achievements of modern medicine. It has contributed most of the basic knowledge in fields such as human physiology and biochemistry, and has played significant roles in fields such as neuroscience and infectious disease. The results have included the near- eradication of polio and the development of organ transplantation, and have benefited both humans and animals. From 19 ...

Taxa Described In 1924
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
