a greenhouse experiment was conducted using completely randomised design (factorial) with three replications to study the residual effect of organic manures (municipal solid waste compost and cow manure), zinc (0 and 50 kgha-1) and boron (0 and 10 kg.ha-1) by using znso4 and h3bo3 salts respectively, (applied earlier for millet (panicum italicum l.) crop) on soil properties and chemical composi...

Heavy metal homeostasis is maintained in plant cells by specialized transporters which compartmentalize or efflux metal ions, maintaining cytosolic concentrations within a narrow range. OsMTP1 is a member of the cation diffusion facilitator (CDF)/metal tolerance protein (MTP) family of metal cation transporters in Oryza sativa, which is closely related to Arabidopsis thaliana MTP1. Functional c...

Phaseolus vulgaris plants, 3, 8, 11, and 13 days old, were inoculated with 0, 2,000, 4,000, or 8,000 second-stage Meloidogyne incognita larvae and maintained under controlled conditions. The photosynthetic rate and the shoot and root concentration of K, Ca, Mn, Fe, Cu, and Zn were determined by destructive assay at 1-27-day intervals and by nondestructive assay of leaves, stems, and roots at 27...

We evaluated the inducibility of nitrate-dependent Fe(II)-EDTA oxidation (NDFO) in non-growth, chloramphenicol-amended, resting-cell suspensions of Dechloromonas sp. strain UWNR4 and Acidovorax sp. strain 2AN. Cells previously incubated with Fe(II)-EDTA oxidized ca. 6-fold more Fe(II)-EDTA than cells previously incubated with Fe(III)-EDTA. This is the first report of induction of NDFO by Fe(II).

Materials and Methods: The silver (Ag), cobalt (Co), chromium (Cr), iron (Fe), mercury (Hg), rubidium (Rb), antimony (Sb), selenium (Se), and zinc (Zn) content and Co/Ag, Cr/Ag, Fe/Ag, Hg/Ag, Sb/Ag, Se/Ag, Co/Rb, Cr/Rb, Fe/Rb, Hg/Rb, Sb/ Rb, Se/Rb, Co/Zn, Cr/Zn, Fe/Zn, Hg/Zn, Sb/Zn, and Se/Zn ratios were estimated in normal bone samples from 27 patients with intact bone (12 females and 15 males...

in order to study the effects of micronutrients application on some morphological traits associated with seed quantity and quality of sugar beet cultivar shirin, an experiment was conducted in 2001-02 at ardabil agricultural research station. based on soil test results, soil ph was 7.62-7.80 with 0.49- 0.53% organic matter content, and the quantity of absorbable p, total n, and k amounts were f...

BACKGROUND & OBJECTIVES Relationship of trace elements with obesity and diabetes is complex, alterations in their metabolism can be induced by the diseases and their complications. To study the role of the trace elements in diabetes and obesity, serum trace elements levels (Cr, Se, Fe, Zn, Cu and Mn) were measured in obese women with or without diabetes as well as healthy women. Further, correl...

The water quality of the Persian Gulf is influenced by various industrial and urban discharges. The study area is a small linked estuary with the Straits of Hormuz in the Persian Gulf. This study was conducted to evaluate anthropogenic assessment, pollution status and potential ecological risk of some heavy metals (Pb,Ni, Zn, and Fe) in intertidal surface sediments of a mangrove estua...

The present investigation deals with the accumulation of heavy metals in fields contaminated with fly ash from a thermal power plant and subsequent uptake in different parts of naturally grown plants. Results revealed that in the contaminated site, the mean level of all the metals (Cd, Zn, Cr, Pb, Cu, Ni, Mn and Fe) in soil and different parts (root and shoots) of plant species were found to be...
