Abstrad: Among the micronutrients essential for plant growth and for microsymbionts, Mo is required in minute amounts. However, since Mo is often sequestered by Feor Al-oxihydroxides, especially in acidic soils, the concentration of the watersoluble molybdate anion available for uptake by plants may be limiting for the plant, even when the total Mo content of the soil is sufficient. In contrast...

background: listeria monocytogenes is an important gram-positive disease-causing bacterium existing in milk and dairy products. inhibitory effects of mentha pulegium essential oil at concentrations of 0.03, 0.015, and 0.0075% on growth of l. monocytogenes were studied in iranian white cheese during 60 days of storage. methods: essential oil of m. pulegium plant, collected from north of iran, wa...

Sulfur deficiency in plants has severe impacts on both growth and nutrient composition. Fumigation with sub-lethal concentrations of H2S facilitates the supply of reduced sulfur via the leaves while sulfate is depleted from the roots. This restores growth while sulfate levels in the plant tissue remain low. In the present study this system was used to reveal interactions of sulfur with other nu...

Synechococcus, C-Phycocyanin, Sulfur Nutrition The cyanobacterium Synechococcus 6301 is able to use a lim ited number o f sulfur compounds as the only source o f sulfur supply such as sulfate, thiosulfate, thioacetic acid, mercaptoacetic acid, thioacetamide, L-cysteine and glutathione. Compounds containg thioether linkages such as methionin or S-methylcysteine and all compounds investigated so ...

Plants are sessile organisms therefore, cannot avoid adverse environmental conditions (such as soil salinity, drought, heat, cold, flooding and heavy metal contamination). These stress factors are a menace for plants, prevent them from reaching their full genetic potential and limit crop productivity worldwide. Soil contamination with heavy metals has become a world wide problem leading to loss...

Nitrogen (N) is an essential macronutrient for plant development and growth, increased N deposition affecting the diversity productivity of plants. The objective this study was to explore growth response Agropyron mongolicum Keng addition determine whether N-induced changes in soil-available nutrients have indirect impacts on biomass A. via regulation root morphological traits NUE. We conducted...

Glutaredoxin S15 is involved in Fe-S cluster transfer in mitochondria influencing lipoic 1 acid-dependent enzymes, plant growth and arsenic tolerance in Arabidopsis 2 3 Elke Ströher, Julia Grassl, Chris Carrie, Ricarda Fenske, James Whelan, A.

Iron-sulfur (Fe/S) cluster-containing proteins catalyse a number of electron transfer and metabolic reactions. Little is known about the biogenesis of Fe/S clusters in the eukaryotic cell. Here, we demonstrate that mitochondria perform an essential role in the synthesis of both intra- and extra-mitochondrial Fe/S proteins. Nfs1p represents the yeast orthologue of the bacterial cysteine desulfur...
