Ferric chelate reduction by sunflower (Helianthus annuus L.) leaves: influence of light, oxygen, iron-deficiency and leaf age
The presence of ferric chelate reducing activity in sunflower [Helianthus annuus L.) leaves has been studied by submerging leaf discs in a solution with Fe(lll)-ethylenediaminetetra-acetate (FeEDTA), bathophenanthroline disulphonate (BPDS) and vacuum infiltration. The effect of different factors on the Fe(lll) reduction rate was studied. Ferric reduction rate was about 10-fold higher in the lig...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولNitric oxide acts downstream of auxin to trigger root ferric-chelate reductase activity in response to iron deficiency in Arabidopsis.
In response to iron (Fe) deficiency, dicots employ a reduction-based mechanism by inducing ferric-chelate reductase (FCR) at the root plasma membrane to enhance Fe uptake. However, the signal pathway leading to FCR induction is still unclear. Here, we found that the Fe-deficiency-induced increase of auxin and nitric oxide (NO) levels in wild-type Arabidopsis (Arabidopsis thaliana) was accompani...
متن کاملIron Deficiency Decreases Suberization in Bean Roots through a Decrease in Suberin-Specific Peroxidase Activity.
The suberin content of young root parts of iron-deficient and iron-sufficient Phaseolus vulgaris L. cv Prélude was determined. The aliphatic components that could be released from suberin-enriched fractions by LiAID(4) depolymerization were identified by gas chromatography-mass spectrometry. In the normal roots, the major aliphatic components were omega-hydroxy acids and dicarboxylic acids in w...
متن کاملIron deficiency decreases renal 25-hydroxyvitamin D3-1α-hydroxylase activity and bone formation in rats
Background: Dietary iron intake is associated with bone metabolism in human and animals. Previous studies have suggested that iron deficiency diminishes bone formation and causes bone loss in rats, however, the detailed mechanisms remain unclear. To clarify the mechanism of the diminishing bone formation in iron deficiency, we examined the renal 25-hydroxyvitamin D3-1α-hydroxylase (1α-hydroxyla...
