Prunetin
Prunetin is an O-methylated isoflavone, a type of flavonoid. It has been isolated for the first time by Finnemore in 1910 in the bark of ''Prunus emarginata'' (the Oregon cherry). Prunetin isolated from pea The pea is most commonly the small spherical seed or the seed-pod of the flowering plant species ''Pisum sativum''. Each pod contains several peas, which can be green or yellow. Botanically, pea pods are fruit, since they contain seeds and d ... roots can act as an attractant for '' Aphanomyces euteiches'' zoospores. It is also an allosteric inhibitor of human liver aldehyde dehydrogenase. Prunetin can lower blood pressure of spontaneously hypertensive rats and relax isolated rat aortic rings through calcium channel block mechanisms in vessel smooth muscles.

Prunus Emarginata
''Prunus emarginata'', the bitter cherry or Oregon cherry, is a species of ''Prunus'' native to western North America, from British Columbia south to Baja California, and east as far as western Wyoming and New Mexico. It is often found in recently disturbed areas or open woods on nutrient-rich soil.Plants of British Columbia''Prunus emarginata''/ref>Jepson Flora''Prunus emarginata''/ref> Description ''Prunus emarginata'' is a deciduous shrub or small tree growing to tall with a slender oval trunk with smooth gray to reddish-brown bark with horizontal lenticels. The leaves are long, thin, egg-shaped, and yellowish-green with unevenly sized teeth on either side. The flowers are small, diameter, with five white petals and numerous hairlike stamens; they are almond-scented, and produced in clusters in spring, and are pollinated by insects. The fruit is a juicy red or purple cherry diameter, which, as the plant's English name suggests, are bitter. As well as reproducing by se ...

Pisum Sativum
The pea is most commonly the small spherical seed or the seed-pod of the flowering plant species ''Pisum sativum''. Each pod contains several peas, which can be green or yellow. Botanically, pea pods are fruit, since they contain seeds and develop from the ovary of a (pea) flower. The name is also used to describe other edible seeds from the Fabaceae such as the pigeon pea (''Cajanus cajan''), the cowpea (''Vigna unguiculata''), and the seeds from several species of ''Lathyrus''. Peas are annual plants, with a life cycle of one year. They are a cool-season crop grown in many parts of the world; planting can take place from winter to early summer depending on location. The average pea weighs between 0.1 and 0.36 gram. The immature peas (and in snow peas the tender pod as well) are used as a vegetable, fresh, frozen or canned; varieties of the species typically called field peas are grown to produce dry peas like the split pea shelled from a matured pod. These are the ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aphanomyces Euteiches
''Aphanomyces euteiches'' is a water mould, or oomycete, plant pathogen responsible for the disease Aphanomyces root rot. The species ''Aphanomyces euteiches'' can infect a variety of legumes. Symptoms of the disease can differ among hosts but generally include reduced root volume and function, leading to stunting and chlorotic foliage. ''Aphanomyces'' root rot is an important agricultural disease in the United States, Europe, Australia, New Zealand, and Japan. Management includes using resistant crop varieties and having good soil drainage, as well as testing soil for the pathogen to avoid infected fields. Hosts and symptoms Hosts of ''Aphanomyces euteiches'' can be annuals or perennials in the legume family, including: pea (''Pisum sativum''), alfalfa (''Medicago sativa''), snap bean and red kidney bean (''Phaseolus vulgaris''), faba bean (''Vicia faba''), red clover (''Trifolium pratense''), and white clover (''Trifolium repens'').Hughes, Teresa J., and Craig R.

Zoospore
A zoospore is a motile asexual spore that uses a flagellum for locomotion. Also called a swarm spore, these spores are created by some protists, bacteria, and fungi to propagate themselves. Diversity Flagella types Zoospores may possess one or more distinct types of flagella - tinsel or "decorated", and whiplash, in various combinations. *Tinsellated (straminipilous) flagella have lateral filaments known as mastigonemes perpendicular to their main axis, which allow for more surface area, and disturbance of the medium, giving them the property of a rudder, that is, used for steering. *Whiplash flagella are straight, to power the zoospore through its medium. Also, the "default" zoospore only has the propelling, whiplash flagella. Both tinsel and whiplash flagella beat in a sinusoidal wave pattern, but when both are present, the tinsel beats in the opposite direction of the whiplash, to give two axes of control of motility. Morphological types In eukaryotes, the four main ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aldehyde Dehydrogenase
Aldehyde dehydrogenases () are a group of enzymes that catalyse the oxidation of aldehydes. They convert aldehydes (R–C(=O)) to carboxylic acids (R–C(=O)). The oxygen comes from a water molecule. To date, nineteen ALDH genes have been identified within the human genome. These genes participate in a wide variety of biological processes including the detoxification of exogenously and endogenously generated aldehydes. Function Aldehyde dehydrogenase is a polymorphic enzyme responsible for the oxidation of aldehydes to carboxylic acids, which leave the liver and are metabolized by the body’s muscle and heart. There are three different classes of these enzymes in mammals: class 1 (low ''K''m, cytosolic), class 2 (low ''K''m, mitochondrial), and class 3 (high ''K''m, such as those expressed in tumors, stomach, and cornea). In all three classes, constitutive and inducible forms exist. ALDH1 and ALDH2 are the most important enzymes for aldehyde oxidation, and both ...

Dalbergia Hainanensis
''Dalbergia'' is a large genus of small to medium-size trees, shrubs and lianas in the pea family, Fabaceae, subfamily Faboideae. It was recently assigned to the informal monophyletic ''Dalbergia'' clade (or tribe): the Dalbergieae. The genus has a wide distribution, native to the tropical regions of Central and South America, Africa, Madagascar and southern Asia. Fossil record A fossil †''Dalbergia phleboptera'' seed pod has been found in a Chattian deposit, in the municipality of Aix-en-Provence in France. Fossils of †''Dalbergia nostratum'' have been found in rhyodacite tuff of Lower Miocene age in Southern Slovakia near the town of Lučenec. Fossil seed pods of †''Dalbergia mecsekense'' have been found in a Sarmatian deposit in Hungary. †''Dalbergia lucida'' fossils have been described from the Xiaolongtan Formation of late Miocene age in Kaiyuan County, Yunnan Province, China.
