environmental effects of gol-e-gohar iron ore mine on groundwater of the area
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
Consequence of Absence of Nitrate Reductase Activity on Photosynthesis in Nicotiana plumbaginifolia Plants.
Chlorate-resistant Nicotiana plumbaginifolia (cv Viviani) mutants were found to be deficient in the nitrate reductase apoprotein (NR(-)nia). Because they could not grow with nitrate as sole nitrogen source, they were cultivated as graftings on wild-type Nicotiana tabacum plants. The grafts of mutant plants were chlorotic compared to the grafts of wild type. Mutant leaves did not accumulate nitr...
متن کاملVulnerability of Prepubertal Mice Testis to Iron Induced Oxidative Dysfunctions In Vivo and Functional Implications
Background The present study describes the susceptibility of prepubertal testis of mice to prooxidant induced oxidative impairments both under in vitro and in vivo exposure conditions. MaterialsAndMethods Following in vitro exposure to iron (5,10 and 25 M), oxidative response measured in terms of lipid peroxidation and hydroperoxide levels in testis of pre pubertal mice (4 wk) was more robust c...
متن کاملAnalysis and effects of cytosolic free calcium increases in response to elicitors in Nicotiana plumbaginifolia cells.
Cell suspensions obtained from Nicotiana plumbaginifolia plants stably expressing the apoaequorin gene were used to analyze changes in cytosolic free calcium concentrations ([Ca(2+)](cyt)) in response to elicitors of plant defenses, particularly cryptogein and oligogalacturonides. The calcium signatures differ in lag time, peak time, intensity, and duration. The intensities of both signatures d...
متن کاملTissue-Specific and Pathogen-lnduced Regulation of a Nicotiana plumbaginifolia
The Nicotiana plumbaginifolia gnl gene encoding a 8-1,3-glucanase isoform has been characterired. The gnl product represents an isoform distinct from the previously identified tobacco 8-1,3-glucanases. By expressing gnl in Escherichia coli, we have determined directly that the encoded protein does, indeed, correspond to a &1,3glucanase. In N. plumbaginifolia, gnl was found to be expressed in ro...
