Flaveria Chlorifolia
''Flaveria chlorifolia'', the clasping yellowtops, is a North American plant species of ''Flaveria'' within the family Asteraceae. It is native to the southwestern United States (New Mexico, western Texas) and northern Mexico (Chihuahua, Coahuila, Nuevo León). ''Flaveria chlorifolia'' is a perennial herb up to 200 cm (80 inches or 6 2/3 feet) tall. One plant can sometimes produce 150 or more flower heads in a branching array, each head with 9-14 yellow disc flowers but no ray flowers.

Asa Gray
Asa Gray (November 18, 1810 – January 30, 1888) is considered the most important American botanist of the 19th century. His ''Darwiniana'' was considered an important explanation of how religion and science were not necessarily mutually exclusive. Gray was adamant that a genetic connection must exist between all members of a species. He was also strongly opposed to the ideas of hybridization within one generation and special creation in the sense of its not allowing for evolution. He was a strong supporter of Darwin, although Gray's theistic evolution was guided by a Creator. As a professor of botany at Harvard University for several decades, Gray regularly visited, and corresponded with, many of the leading natural scientists of the era, including Charles Darwin, who held great regard for him. Gray made several trips to Europe to collaborate with leading European scientists of the era, as well as trips to the southern and western United States. He also built an extensive ne ...

Flora Of The South-Central United States
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phy ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Quercetin 3,3'-bissulfate
Quercetin is a plant flavonol from the flavonoid group of polyphenols. It is found in many fruits, vegetables, leaves, seeds, and grains; capers, red onions, and kale are common foods containing appreciable amounts of it. It has a bitter flavor and is used as an ingredient in dietary supplements, beverages, and foods. Occurrence Quercetin is a flavonoid widely distributed in nature. The name has been used since 1857, and is derived from ''quercetum'' (oak forest), after the oak genus ''Quercus''. It is a naturally occurring polar auxin transport inhibitor. Quercetin is one of the most abundant dietary flavonoids, with an average daily consumption of 25–50 milligrams. In red onions, higher concentrations of quercetin occur in the outermost rings and in the part closest to the root, the latter being the part of the plant with the highest concentration. One study found that organically grown tomatoes had 79% more quercetin than non-organically grown fruit. Quercetin is present ...

Adenosine 3',5'-bisphosphate
Adenosine 3',5'-bisphosphate is a form of an adenosine nucleotide with two phosphate groups attached to different carbons in the ribose ring. This is distinct from adenosine diphosphate, where the two phosphate groups are attached in a chain to the 5' carbon atom in the ring. Adenosine 3',5'-bisphosphate is produced as a product of sulfotransferase enzymes from the donation of a sulfate group from the coenzyme 3'-phosphoadenosine-5'-phosphosulfate. This product is then hydrolysed by 3'(2'),5'-bisphosphate nucleotidase to give adenosine monophosphate, which can then be recycled into adenosine triphosphate. See also * Adenine * Sulfur metabolism * Acetyl-CoA Acetyl-CoA (acetyl coenzyme A) is a molecule that participates in many biochemical reactions in protein, carbohydrate and lipid metabolism.

Flaveria
''Flaveria'' is a genus of plants in the family Asteraceae. They are sometimes called yellowtops. Some are annual or perennial herbs and some are shrubs. They bear yellow flowers in heads, with zero, one, or two ray florets in each head. These plants are found in the Americas, Asia, Africa, and Australia. While some members of this genus use the more common carbon fixation pathway, others are plants, and some are intermediate. With closely related species exhibiting different forms of metabolism, ''Flaveria'' has been a model genus for studies on the evolution of photosynthesis. A monograph by A.M. Powell from 1978 is the most comprehensive study of morphology and biogeography for the ''Flaveria'' species to date. Molecular phylogenetic studies have clarified many of the evolutionary relationships between ''Flaveria'' species. ; Species * '' Flaveria angustifolia'' - Mexico (Oaxaca, Puebla, Guerrero); – intermediate * '' Flaveria anomala'' - Mexico (San Luis Potosí, ...

Quercetin-3-sulfate 3'-sulfotransferase
In enzymology, a quercetin-3-sulfate 3'-sulfotransferase () is an enzyme that catalyzes the chemical reaction :3'-phosphoadenylyl sulfate + quercetin 3-sulfate \rightleftharpoons adenosine 3',5'-bisphosphate + quercetin 3,3'-bissulfate Thus, the two substrates of this enzyme are 3'-phosphoadenylyl sulfate and quercetin 3-sulfate, whereas its two products are adenosine 3',5'-bisphosphate and quercetin 3,3'-bissulfate. This enzyme belongs to the family of transferases, specifically the sulfotransferases, which transfer sulfur-containing groups. The systematic name A systematic name is a name given in a systematic way to one unique group, organism, object or chemical substance, out of a specific population or collection. Systematic names are usually part of a nomenclature. A semisystematic name or semitrivial ... of this enzyme class is 3'-phosphoadenylyl-sulfate:quercetin-3-sulfate 3'-sulfotransferase.
