Lead is a heavy metal of particular concern with respect to environmental quality and health. The lack of plant species that accumulate and tolerate Pb is a limiting factor to understand the molecular mechanisms involved in Pb tolerance. In this study we identified Hirschfeldia incana, a Brassicaceae collected from metalliferous mine spoils in Morocco, as a Pb accumulator plant. H. incana exhib...

Dioxygenase, Flavonoid Biosynthesis, Flavonols, Matthiola incana Soluble enzyme preparations from flower buds of Matthiola incana catalysed the conversion of dihydrokaempferol to kaempferol and of dihydroquercetin to quercetin. The reaction required 2-oxoglutarate, ascorbate and Fe2+ as cofactors and had a pH-optimum at about 7.0. Highest enzyme activity was already present in the youngest buds...

In our continued investigations of the plant Caryopteris incana, five new iridoid glucosides 1-5, including two cis-trans-isomers, 3 and 4, along with six known compounds 6-11, were isolated from the n-butyl alcohol (n-BuOH) soluble fraction of whole dried material of Caryopteris incana. Their structures were established by a combination of spectroscopic techniques, including 1D and 2D NMR and ...

the essential oils of the aerial parts of a. armeniaca and a. incana , collected from arasbaran area (east azarbaijan province, iran) were extracted by hydrodistillation and analyzed by gc-ms. in total, 16 and 40 constituents were identified and quantified in the oils of a. armeniaca and a. incana representing 80.5% and 84.6% of the oils, respectively. the essential oil of a. armeniaca was main...

Background and objectives: Residues of medicinal plants after extraction and weeds are suitable candidates for bioethanol production. Significant barriers exist to make the conversion of lignocellulosic feedstock to biofuel cost effective and environmentally friendly; one of which is the lignin polymer. Brassicaceae family is one of the potential targets for biofuel production....

Various studies on Phragmanthera incana (mistletoe) did not intensify toxicity. Toxicological evaluation of Phragmanthera incana, a species of mistletoe growing on two plant hosts namely Cocoa (Theobroma cacao) and Kolanut (Cola nitida) in South-western Nigeria was carried out with the observation of Wistar rats’ haematological and serum biochemical changes for a period of thirty-day administra...

ABEYSEKERA, R. M., NEWCOMB, W . , SILVESTER, W. B., and TORREY, J. G. 1990. A freeze-fracture electron microscopic study of Frankia in root nodules of Alnus incana grown at three oxygen tensions. Can. J. Microbiol. 36: 97-108. Nodulated plants of Alnus incana ssp. rugosa and ssp. incana were grown with the roots exposed to 5,21, and 40 kPa 02. The nodules were studied by freeze-fracture transmi...

ABSTRACT The establishment and growth of trees can be compromised by soil contamination which can reduce populations of key microbial symbionts. We describe the colonisation of grey alder (Alnus incana) by Frankia from 10 urban soils with varying degrees of organic and inorganic pollution. Principal components analysis (PCA) of soil chemical profiles showed a separation of remediated and unreme...
