Zinc is a minor micronutrient that also involved in carbohydrate, protein synthesis metabolisms. The present study was carried out to analyze response DNSA, proline, and MDA (Malondialdehit) responses the form of zinc oxide nanoparticles (ZnO NPs) Pisum sativum, for period 21st 35th days. Two P. sativum (Maro Tarım Kars) were used as material presence 0.8 ppm 1.8 ZnO nanoparticulate. length bio...

The changes in photosynthetic activity, as well the activity of nitrogen-metabolism enzymes, intensity lipid peroxidation, and proline content were studied Triticum aestivum L. plants after their incubation at a low CO2 concentration sealed chamber for 10 d. deficiency (-CO2) compared to normal (control) led decrease rate O2 gas exchange plateau light cur...

Unselected and sodium sulfate tolerant callus cultures of Brassica napus L. cv Westar were grown on media supplemented with mannitol, NaCl, or Na(2)SO(4). In all cases, growth of tolerant callus, measured on a fresh weight or dry weight basis, was greater than that of unselected callus, which was also subject to necrosis on high levels of salt. Tissue water potential became more negative in bot...

Investigating the effect of various sources sulfurous compounds along with inoculation Thiobacillus bacteria on corn plants under stress conditions lead and zinc metals, an experiment executed at zanjan uni researching green house. The treatments include elemental sulfur (0.75, 1.25 2 g/kg soil), (1, 3 soil) potassium sulfate (0.5, 1 1.5 soil ). results showed that traits were significant in al...

The metabolism of glutamate into ornithine, arginine, proline, and polyamines is a major network of nitrogen-metabolizing pathways in plants, which also produces intermediates like nitric oxide, and γ-aminobutyric acid (GABA) that play critical roles in plant development and stress. While the accumulations of intermediates and the products of this network depend primarily on nitrogen assimilati...

Mitochondrial proline oxidation was studied as a tool to investigate the regulation of the fate of intramitochondrially generated glutamate. Aspartate formation from proline was less than with glutamate as a substrate and was not appreciably stimulated by malate, indicating that the supply of oxalacetate was not limiting. A lag in aspartate synthesis from proline occurred which was relieved by ...

one of the effects of reducing water content on soil is reduction of growth and development of seedlings and variation of field development of them. it was found that seed priming improves some characteristics of seedling and plant. an experiment was conducted for evaluating the effect of seed priming by salicylic acid on some characteristics of barley seed at early growth stages, antioxidant e...

We conducted a study to examine the growth and physiological changes in 12 different ecotypes of Sesuvium portulacastrum collected from Hainan Island China. These were subjected concentrations (0, 200, 400, 600 mmol/L) sodium chloride (NaCl) salt stress for 14 days. also analyzed expression metabolic genes related response. Under low stress, indicators such as plant height region K (0 mmol/L: 4...
