Arabidopsis
''Arabidopsis'' (rockcress) is a genus in the family Brassicaceae. They are small flowering plants related to cabbage and mustard. This genus is of great interest since it contains thale cress (''Arabidopsis thaliana''), one of the model organisms used for studying plant biology and the first plant to have its entire genome sequenced. Changes in thale cress are easily observed, making it a very useful model. Status Currently, the genus ''Arabidopsis'' has nine species and a further eight subspecies recognised. This delimitation is quite recent and is based on morphological and molecular phylogenies by O'Kane and Al-Shehbaz and others. Their findings confirm the species formerly included in ''Arabidopsis'' made it polyphyletic. The most recent reclassification moves two species previously placed in ''Cardaminopsis'' and ''Hylandra'' and three species of ''Arabis'' into ''Arabidopsis'', but excludes 50 that have been moved into the new genera '' Beringia, Crucihimalaya, Ianhedge ...

Thale Cress
''Arabidopsis thaliana'', the thale cress, mouse-ear cress or arabidopsis, is a small flowering plant native to Eurasia and Africa. ''A. thaliana'' is considered a weed; it is found along the shoulders of roads and in disturbed land. A winter annual with a relatively short lifecycle, ''A. thaliana'' is a popular model organism in plant biology and genetics. For a complex multicellular eukaryote, ''A. thaliana'' has a relatively small genome around 135 megabase pairs. It was the first plant to have its genome sequenced, and is a popular tool for understanding the molecular biology of many plant traits, including flower development and light sensing. Description ''Arabidopsis thaliana'' is an annual (rarely biennial) plant, usually growing to 20–25 cm tall. The leaves form a rosette at the base of the plant, with a few leaves also on the flowering stem. The basal leaves are green to slightly purplish in color, 1.5–5 cm long, and 2–10 mm broad, with an ent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nottingham Arabidopsis Stock Centre
The Nottingham Arabidopsis Stock Centre (NASC) provides seed and information resources to the International Arabidopsis Genome Project and the wider research community. It is based in the School of Biosciences at the University of Nottingham's Sutton Bonington Campus, in the English county of Nottinghamshire. It holds more than 800,000 different stocks of seed representing nearly a million genotypes and provided a Genechip service from 2002-2013. Newly generated research stocks, mutants or lines of Arabidopsis thaliana are donated as samples to NASC where they are maintained and thus are made available to scientists worldwide. Established in 1990 as part of the Plant Molecular Biology initiative of the Agricultural and Food Research Council (AFRC), the Centre is currently funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and the University of Nottingham. The Stock Centre was founded by Dr Bernard Mulligan; Directed from 1991 to 1999 by Dr Mary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Model Organism
A model organism (often shortened to model) 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. Studying model organisms can be informative, but care must be taken when generalizing from one organism to another. In researching human disease, model organisms allow for better understanding the disease process without the added risk of harming an actual human. The species chosen will usually meet a determined taxonomic equivalency to humans, so as to react to disease or its treatment in a way that resembles ...

Arabidopsis Biological Resource Center
The Arabidopsis Biological Resource Center (ABRC) was established at Ohio State University in September, 1991. Primary support for the ABRC is provided by a National Science Foundation grant. The mission of the ABRC is to acquire, preserve and distribute seed and DNA resources that are useful to the Arabidopsis research community. New seed and DNA enter ABRC through donation by national and international researchers. An identifying number is assigned to each stock. The stock is then evaluated, documented and made available for distribution. The preservation of seed and DNA stocks is conducted according to strict, defined protocols. Backups of stocks are maintained to ensure preservation. The ABRC's holdings and stock distribution rates have increased rapidly so that presently hundreds of thousands of stocks are available. More than 100,000 stocks are shipped annually to researchers in more than 60 countries, and modest fees for stocks are charged as part of a not-for-profit cost- ...

Brassicaceae
Brassicaceae () or (the older) Cruciferae () is a medium-sized and economically important family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. Most are herbaceous plants, while some are shrubs. The leaves are simple (although are sometimes deeply incised), lack stipules, and appear alternately on stems or in rosettes. The inflorescences are terminal and lack bracts. The flowers have four free sepals, four free alternating petals, two shorter free stamens and four longer free stamens. The fruit has seeds in rows, divided by a thin wall (or septum). The family contains 372 genera and 4,060 accepted species. The largest genera are ''Draba'' (440 species), ''Erysimum'' (261 species), ''Lepidium'' (234 species), ''Cardamine'' (233 species), and ''Alyssum'' (207 species). The family contains the cruciferous vegetables, including species such as ''Brassica oleracea'' (cultivated as cabbage, kale, cauliflower, broccoli and collards), ...

Gustav Heynhold
Gustav Heynhold (or ''Gustav Heinhold''; 1800–1860) was a German botanist who worked at the botanic gardens of Dresden and Frankfurt Frankfurt, officially Frankfurt am Main (; Hessian: , "Frank ford on the Main"), is the most populous city in the German state of Hesse. Its 791,000 inhabitants as of 2022 make it the fifth-most populous city in Germany. Located on its na .... In 1828 he was in Trieste where he carried out mapping and published "Uebersicht der Vegetation in den Umgebungen Triest's; von Hrn. Gustav Heynhold zu Dresden." His best-known work was the ''Nomenclator Botanicus Hortensis'', an index of the botanical names of garden plants. It is not certain whether he had an academic degree or title. In 1846 the "Botanischen Centralblatt für Deutschland" listed him as a private scholar in Dresden. In total he was responsible for naming some 426 plant species. In 1841, he renamed ''Arabis thaliana'' as ''Arabidopsis thaliana'' (L.) Heynh. ''Arabidopsis'' was the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salyut 7
Salyut 7 (russian: Салют-7; en, Salute 7) (a.k.a. DOS-6, short for Durable Orbital Station) was a space station in low Earth orbit from April 1982 to February 1991. It was first crewed in May 1982 with two crew via Soyuz T-5, and last visited in June 1986, by Soyuz T-15. Various crew and modules were used over its lifetime, including 12 crewed and 15 uncrewed launches in total. Supporting spacecraft included the Soyuz T, Progress (spacecraft), Progress, and TKS spacecraft. It was part of the Soviet Union, Soviet Salyut programme, and launched on 19 April 1982 on a Proton (rocket), Proton rocket from Baikonur Cosmodrome Site 200, Site 200/40 at the Baikonur Cosmodrome in the Soviet Union. Salyut 7 was part of the transition from monolithic to modular space stations, acting as a testbed for docking of additional modules and expanded station operations. It was the eighth space station of any kind launched. Salyut 7 was the last of both the second generation of DOS-series spa ...

Hylandra
''Hylandra suecica'' is a species of cruciferous plants. Its origin is Swedish. It was originally described by Elias Magnus Fries in 1846 as a subspecies of "''Arabis thaliana''" (now ''Arabidopsis thaliana'') and later moved to its own genus by Áskell Löve Áskell Löve (20 October 1916 – 29 May 1994) was an Icelandic systematic botanist, particularly active in the Arctic.
