A plant genus of the family Anacardiaceae, order Sapindales, subclass Rosidae. It is a source of gallotannin (TANNIC ACID) and of somewhat edible fruit. Do not confuse with TOXICODENDRON which used to be part of this genus.
A genus (formerly part of Rhus genus) of shrubs, vines, or trees that yields a highly allergenic oleoresin which causes a severe contact dermatitis (DERMATITIS, TOXICODENDRON). The most toxic species are Toxicodendron vernix (poison sumac), T. diversilobum (poison oak), and T. radicans (poison ivy). T. vernicifera yields a useful varnish from which certain enzymes (laccases) are obtained.
A copper-containing oxidoreductase enzyme that catalyzes the oxidation of 4-benzenediol to 4-benzosemiquinone. It also has activity towards a variety of O-quinols and P-quinols. It primarily found in FUNGI and is involved in LIGNIN degradation, pigment biosynthesis and detoxification of lignin-derived products.
An enzyme that converts ascorbic acid to dehydroascorbic acid. EC
Compounds based on CHALCONE. They are important intermediates in the formation of FLAVONOIDS.
Plants or plant parts which are harmful to man or other animals.
The outer layer of the woody parts of plants.
A plant genus of the family GERANIACEAE. Geranium is also used as a common name for PELARGONIUM.
A division of the plant kingdom. Bryophyta contains the subdivision, Musci, which contains the classes: Andreaeopsida, BRYOPSIDA, and SPHAGNOPSIDA.
A plant genus in the family PINACEAE, order Pinales, class Pinopsida, division Coniferophyta. They are evergreen trees mainly in temperate climates.
A functional system which includes the organisms of a natural community together with their environment. (McGraw Hill Dictionary of Scientific and Technical Terms, 4th ed)
Woody, usually tall, perennial higher plants (Angiosperms, Gymnosperms, and some Pterophyta) having usually a main stem and numerous branches.
The family Cervidae of 17 genera and 45 species occurring nearly throughout North America, South America, and Eurasia, on most associated continental islands, and in northern Africa. Wild populations of deer have been established through introduction by people in Cuba, New Guinea, Australia, New Zealand, and other places where the family does not naturally occur. They are slim, long-legged and best characterized by the presence of antlers. Their habitat is forests, swamps, brush country, deserts, and arctic tundra. They are usually good swimmers; some migrate seasonally. (Walker's Mammals of the World, 5th ed, p1362)
A transmissible spongiform encephalopathy (prion disease) of DEER and elk characterized by chronic weight loss leading to death. It is thought to spread by direct contact between animals or through environmental contamination with the prion protein (PRIONS).
PLANTS, or their progeny, whose GENOME has been altered by GENETIC ENGINEERING.
The science of developing, caring for, or cultivating forests.
A plastic substance deposited by insects or obtained from plants. Waxes are esters of various fatty acids with higher, usually monohydric alcohols. The wax of pharmacy is principally yellow wax (beeswax), the material of which honeycomb is made. It consists chiefly of cerotic acid and myricin and is used in making ointments, cerates, etc. (Dorland, 27th ed)
The fleshy or dry ripened ovary of a plant, enclosing the seed or seeds.
Use of written, printed, or graphic materials upon or accompanying a product or its container or wrapper. It includes purpose, effect, description, directions, hazards, warnings, and other relevant information.
The outer covering of the body that protects it from the environment. It is composed of the DERMIS and the EPIDERMIS.
Use of written, printed, or graphic materials upon or accompanying a food or its container or wrapper. The concept includes ingredients, NUTRITIONAL VALUE, directions, warnings, and other relevant information.
Six-membered heterocycles containing an oxygen and a nitrogen.
Chemical reactions effected by light.
A strong oxidizing agent used in aqueous solution as a ripening agent, bleach, and topical anti-infective. It is relatively unstable and solutions deteriorate over time unless stabilized by the addition of acetanilide or similar organic materials.
Concentrated pharmaceutical preparations of plants obtained by removing active constituents with a suitable solvent, which is evaporated away, and adjusting the residue to a prescribed standard.
Facilities which provide care for infants.
Schools for children usually under five years of age.
