Retama Monosperma
''Retama monosperma'', the bridal broom or bridal veil broom, is a flowering bush species in the genus ''Retama'', native to the western Mediterranean Basin (from Portugal, Morocco and Canary Islands to Italy and Egypt). ''Retama monosperma'' forms root nodules with '' Ensifer fredii''. The larvae of the moths '' Phyllonorycter hesperiella'' and '' Phyllonorycter spartocytisi'' feed on ''R. monosperma''. The seeds contain cytisine, a toxic alkaloid. Fifteen other quinolizidine and three dipiperidine alkaloids can also be isolated from different parts of the plant. In particular, the presence of (+)-sparteine Sparteine is a class 1a antiarrhythmic agent; a sodium channel blocker. It is an alkaloid and can be extracted from scotch broom. It is the predominant alkaloid in '' Lupinus mutabilis'', and is thought to chelate the bivalent cations calcium and ..., α- and β- isosparteine, (+)-17- oxosparteine, (-)- lupanine, 5,6-dehydrolupanine, (-)- anagyrine, (-)- N-methylcytis ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1753
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ...

Genisteae
Genisteae is a tribe of trees, shrubs and herbaceous plants in the subfamily Faboideae of the family Fabaceae. It includes a number of well-known plants including broom, lupine (lupin), gorse and laburnum. The tribe's greatest diversity is in the Mediterranean, and most genera are native to Europe, Africa, the Canary Islands, India and southwest Asia. However, the largest genus, ''Lupinus'', is most diverse in North and South America. ''Anarthrophytum'' and ''Sellocharis'' are also South American and ''Argyrolobium'' ranges into India. Description The Genisteae arose 32.3 ± 2.9 million years ago (in the Oligocene). The members of this tribe consistently form a monophyletic clade in molecular phylogenetic analyses. The tribe does not currently have a node-based definition, but several morphological synapomorphies have been identified: … bilabiate calyces with a bifid upper lip and a trifid lower lip, … the lack of an aril, or the presence of an aril but on the shor ...

Anagyrine
Anagyrine is a teratogenic alkaloid first isolated from (and named for) ''Anagyris foetida'' in the year 1885 by French biologists Hardy and Gallois. ''A. foetida'' (family Fabaceae), the Stinking Bean Trefoil, is a highly toxic shrub native to the Mediterranean region, with a long history of use in folk medicine. In the year 1939 Anagyrine was found by James Fitton Couch to be identical to an alkaloid present in many species belonging to the plant genus ''Lupinus'' (lupins).Couch, James Fitton. "Lupine Studies. XIV.1 The Isolation of Anagyrine FromLupinus Laxiflorusvar.silvicola C. P. Smith." ''Journal of the American Chemical Society'' 61.12 (1939): 3327-328. https://pubs.acs.org/doi/pdf/10.1021/ja01267a027 Retrieved at 12.18 on 28/11/22. The toxin can cause crooked calf disease if a cow ingests the plant during certain periods of pregnancy. Background The toxicity of certain species of ''Lupinus'' plants has been known for several years. The plant is very common in western Nor ...

Sparteine
Sparteine is a class 1a antiarrhythmic agent; a sodium channel blocker. It is an alkaloid and can be extracted from scotch broom. It is the predominant alkaloid in ''Lupinus mutabilis'', and is thought to chelate the bivalent cations calcium and magnesium. It is not FDA approved for human use as an antiarrhythmic agent, and it is not included in the Vaughan Williams classification of antiarrhythmic drugs. It is also used as a chiral ligand in organic chemistry, especially in syntheses involving organolithium reagents. Biosynthesis Sparteine is a lupin alkaloid containing a tetracyclic bis-quinolizidine ring system derived from three C5 chains of lysine, or more specifically, L-lysine. The first intermediate in the biosynthesis is cadaverine, the decarboxylation product of lysine catalyzed by the enzyme lysine decarboxylase (LDC). Three units of cadaverine are used to form the quinolizidine skeleton. The mechanism of formation has been studied enzymatically, as well as with ...
