P-Hydroxybenzoic Acid Glucoside
4-Hydroxybenzoic acid 4-''O''-glucoside is a glucoside of ''p''-hydroxybenzoic acid. It can be found in mycorrhizal (''Picea abies''-''Lactarius deterrimus'' and ''Picea abies''-''Laccaria amethystina'') and non-mycorrhizal roots of Norway spruces (''Picea abies''). The enzyme 4-hydroxybenzoate 4-O-beta-D-glucosyltransferase can be found in the pollen of ''Pinus densiflora ''Pinus densiflora'', also called the Japanese red pine, the Japanese pine, or Korean red pine, is a species of pine tree native to East Asia. Distribution and habitat ''P. densiflora'' has a home range that includes Japan, the Korean Peninsula, ...''.

P-Hydroxybenzoic Acid
4-Hydroxybenzoic acid, also known as ''p''-hydroxybenzoic acid (PHBA), is a monohydroxybenzoic acid, a phenolic derivative of benzoic acid. It is a white crystalline solid that is slightly soluble in water and chloroform but more soluble in polar organic solvents such as alcohols and acetone. 4-Hydroxybenzoic acid is primarily known as the basis for the preparation of its esters, known as parabens, which are used as preservatives in cosmetics and some ophthalmic solutions. It is isomeric with 2-hydroxybenzoic acid, known as salicylic acid, a precursor to aspirin, and with 3-hydroxybenzoic acid. Natural occurrences It is found in plants of the genus ''Vitex'' such as '' V. agnus-castus'' or '' V. negundo'', and in ''Hypericum perforatum'' (St John's wort). It is also found in '' Spongiochloris spongiosa'', a freshwater green alga. The compound is also found in '' Ganoderma lucidum'', a medicinal mushroom with the longest record of use. ''Cryptanaerobacter phenolicus'' is a ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lactarius Deterrimus
''Lactarius deterrimus'', also known as false saffron milkcap or orange milkcap, is a species of fungus in the family (biology), family Russulaceae. The fungus produces medium-sized basidiocarp, fruit bodies (mushrooms) with orangish pileus (mycology), caps up to wide that develop green spots in old age or if injured. Its orange-coloured latex stains maroon within 30 minutes. ''Lactarius deterrimus'' is a mycorrhizal fungus that associates with Picea abies, Norway spruce and bearberry. The species is distributed in Europe, but has also found in parts of Asia. A visually similar species in the United States and Mexico is not closely related to the European species. Fruit bodies appear between late June and November, usually in spruce forests. Although the fungus is edible mushrooms, edible—like all ''Lactarius (fungus), Lactarius'' mushrooms from the section (biology), section ''Lactarius (fungus)#Section Deliciosi, Deliciosi''—its taste is often bitter, and it is not h ...

Laccaria Amethystina
''Laccaria amethystina'', commonly known as the "amethyst deceiver", is a small brightly colored mushroom, that grows in deciduous and coniferous forests. The mushroom itself is edible, but can absorb arsenic from the soil. Because its bright amethyst coloration fades with age and weathering, it becomes difficult to identify, hence the common name "deceiver". This common name is shared with its close relation ''Laccaria laccata'' that also fades and weathers. It is found mainly in Northern temperate zones, though it is reported to occur in tropical Central and South America as well. Recently, some of the other species in the genus have been given the common name of "deceiver". Taxonomy This species was first described in 1778 by well-known English botanist and apothecary William Hudson as ''Agaricus amethystinus'', and later put into the genus ''Laccaria'' by Mordecai Cubitt Cooke. The amethyst deceiver has had many binomials over a great many years, but reference to the amet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Picea Abies
''Picea abies'', the Norway spruce or European spruce, is a species of spruce native to Northern Europe, Northern, Central Europe, Central and Eastern Europe. It has branchlets that typically hang downwards, and the largest cones of any spruce, 9–17 cm long. It is very closely related to the Siberian spruce (''Picea obovata''), which replaces it east of the Ural Mountains, and with which it hybridizes freely. The Norway spruce has a wide distribution for it being planted for its wood, and is the species used as the main Christmas tree in several countries around the world. It was the first gymnosperm to have its genome sequenced. The Latin binomial nomenclature, specific epithet ''abies'' means “like ''Abies'', Fir tree” Description Norway spruce is a large, fast-growing evergreen coniferous tree growing tall and with a trunk diameter of 1 to 1.5 m. It can grow fast when young, up to 1 m per year for the first 25 years under good conditions, but becomes slower once ov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
4-hydroxybenzoate 4-O-beta-D-glucosyltransferase
In enzymology, a 4-hydroxybenzoate 4-O-beta-D-glucosyltransferase () is an enzyme that catalyzes the chemical reaction :UDP-glucose + 4-hydroxybenzoate \rightleftharpoons UDP + 4-(beta-D-glucosyloxy)benzoate Thus, the two substrates of this enzyme are UDP-glucose and 4-hydroxybenzoate, whereas its two products are UDP and 4-(beta-D-glucosyloxy)benzoate. This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. 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 UDP-glucose:4-hydroxybenzoate 4-O-beta-D-glucosyltransferase. Other names in common use include uridine diphosphoglucose-4-hydroxybenzoate glucosyltransferase, UDP-glucose:4-(beta-D-glucopyranosyloxy)benzoic acid, glucosyltransferase, HBA g ...

Pinus Densiflora
''Pinus densiflora'', also called the Japanese red pine, the Japanese pine, or Korean red pine, is a species of pine tree native to East Asia. Distribution and habitat ''P. densiflora'' has a home range that includes Japan, the Korean Peninsula, northeastern China (Heilongjiang, Jilin, Liaoning, Shandong) and the extreme southeast of Russia (in Siberia, southern Primorsky Krai). Description The leaves are needle-like, long, with two per fascicle. The cones are long. It is closely related to Scots pine, differing in the longer, slenderer leaves which are mid-green without the glaucous-blue tone of Scots pine. This pine has become a popular ornamental and has several cultivars, but in the winter it becomes yellowish. The height of this tree is . The plant prefers full sun on well-drained, slightly acidic soil. Cultivation In Japan it is known as and . It is widely cultivated in Japan both for timber production and as an ornamental tree, and plays an important part in the classic ...
