Mistletoe, Viscum

Certain flavonoids are used by plants to protect them from invasion by parasites. For example, poplar (Populus spp.) cultivars produce a chemical barrier to parasitization by mistletoe (Viscum album).Resistant poplar cultivars were significantly higher in flavonols and flavones compared to susceptible cultivars. Likewise, in Streblus asper the bark and wood of trees that are resistant to the parasite Cuscuta reflexa hold higher levels of flavonoids, as well as steroids and alkaloids. [Pg.422]

The word viscosity comes from the Latin word for mistletoe, viscum. Anyone familiar with this plant is aware that it exudes a viscous sticky sap when harvested. Viscosity is defined after Isaac Newton in his Principia as the ratio of stress to shear rate and is given the symbol T. Stress (a) in a fluid is simply force/area, like pressure, and has the units of pascals (Pa S.I. units) or dynes/cm2 (c.g.s.). Shear rate or strain rate (y or dyldt) is the differential of strain (y) with respect to time. Strain is simply the change in shape of a volume of fluid as a result of an applied stress and has no units. The shear rate is in fact a velocity gradient, not a flow rate. It has the bizarre units of 1/time (sec-1) and is the velocity at a given point in the fluid divided by the distance of that point from the stationary plane. [Pg.1137]

Some members occur in temperate zones, but (his family is primarily tropical. Its economic importance derives largely from the familiar mistletoe (Viscum album). [Pg.131]

Similar toxic RIPs are found in other plants. Examples are trichosanthin, a type I toxin from the root tubers of Trichosanthes kirilowii (Cucurbitaceae), abrin, a type II toxin from the small brightly coloured red and black jequirity seeds (Abrus precatorius Leguminosae/Fabaceae), and viscumin, a type II toxin from the leaf and stems of mistletoe (Viscum album, Loranthaceae). [Pg.435]

In Gymnosperms the microsporophylls or stamens are usually sessile, whereas in Angiosperms the microsporophylls are nearly always stalked. Rarely do we find sessile anthers among Angiosperms, an instance of this being seen in Mistletoe (Viscum) where the anthers are set on the staminal leaf. [Pg.59]

MISTLETOE, Viscum album L., family Viscaceae, is a semi-parasite, growing on leafy trees. There are other subspecies that grow on coniferous trees. The mistletoe takes water and salts from the host plant, but it has its own photosynthesis and its secondary metabolites are totally different from those of the host plant. Five main groups are said to be characteristic of mistletoe ... [Pg.96]

Phenethylamine is one of the constituents of the extract of mistletoe Viscum album L.). Barger and Dale (176) were the first to describe the hypertensive and apparently sympathomimetic effects observed following injection into the animal. Bry (173) described the stimulating properties of the /3-phenethylamine. Small doses (0.2-1.0 mg. intravenously) administered to the cat are hypertensive, but large doses (20-125 mg.) provoke a hypotension due to a depression of the myocardium (176a). Barbour... [Pg.130]
