	Piceol Piceol is a phenolic compound found in the needles and in mycorrhizal roots of Norway spruces (''Picea abies''). Picein is the glucoside of piceol. Uses Piceol is used in the synthesis of several pharmaceutical drugs including octopamine, sotalol, bamethan, and dyclonine. Piceol can be used to make acetaminophen by oxime formation with hydroxylamine and subsequent Beckmann rearrangement in acid. Anticonvulsants are also possible by Mannich reaction: Metabolism Diprenylated derivatives of piceol can be isolated from '' Ophryosporus macrodon''. 4-Hydroxyacetophenone monooxygenase is an enzyme that transforms piceol into O-acetylhydroquinone. This enzyme is found in '' Pseudomonas fluorescens''. See also Paroxypropione, where the acetyl group is replaced by a propionyl group. Apocynin Apocynin, also known as acetovanillone, is a natural organic compound structurally related to vanillin. It has been isolated from a variety of plant sources and is being studied for i ...

picture info	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]

picture info	Mycorrhiza A mycorrhiza (from Greek μύκης ', "fungus", and ῥίζα ', "root"; pl. mycorrhizae, mycorrhiza or mycorrhizas) is a symbiotic association between a fungus and a plant. The term mycorrhiza refers to the role of the fungus in the plant's rhizosphere, its root system. Mycorrhizae play important roles in plant nutrition, soil biology, and soil chemistry. In a mycorrhizal association, the fungus colonizes the host plant's root tissues, either intracellularly as in arbuscular mycorrhizal fungi (AMF or AM), or extracellularly as in ectomycorrhizal fungi. The association is sometimes mutualistic. In particular species or in particular circumstances, mycorrhizae may have a parasitic association with host plants. Definition A mycorrhiza is a symbiotic association between a green plant and a fungus. The plant makes organic molecules such as sugars by photosynthesis and supplies them to the fungus, and the fungus supplies to the plant water and mineral nutrients, such as phosp ...
