Sulfate is a macronutrient required for cell growth and development. Arabidopsis has two high-affinity sulfate transporters (SULTR1;1 and SULTR1;2) that represent the sulfate uptake activities at the root surface. Sulfur limitation (-S) response relevant to the function of SULTR1;2 was elucidated in this study. We have isolated a novel T-DNA insertion allele defective in the SULTR1;2 sulfate tr...

Iron-sulfur proteins for which crystal structures are known all contain several NH .. S hydrogen bonds between backbone amide groups and sulfur atoms in the iron-sulfur cluster. Moreover, there is an approximate correlation between the number of such NH ... S hydrogen bonds in the environment of a given (CysS)4Fe4S4* cluster and its oxidation-reduction potential (Carter, C. W., Jr. (1977) J. Bi...

Preparative and structural studies on sulfur-linked carborane icosahedra: 2-phenyl-ortho-carboranylsulfur systems (2-Ph-1, 2-C2B10H10)2X (X = S, S2 or SO), and ortho-carboran-di-yl systems (1, 2-C2H10H10Y)2 (Y = S or SO) A.

The hyperthermophilic archaeon Thermococcus onnurineus NA1 has been shown to produce H₂ when using CO, formate, or starch as a growth substrate. This strain can also utilize elemental sulfur as a terminal electron acceptor for heterotrophic growth. To gain insight into sulfur metabolism, the proteome of T. onnurineus NA1 cells grown under sulfur culture conditions was quantified and compared wi...

In this research, the effects of important parameters, including the molar ratio of acetic acid to sulfur(S) , sonication time, temperature, and hydrogen the molar ratio of peroxide to sulfur on the performance of ultrasound-assisted oxidative desulfurization were studied using the response surface method (RSM). To this end, a model fuel containing n-decane and dibenzothiophene at a concentrati...

BACKGROUND Acidithiobacillus caldus (A. caldus) is widely used in bio-leaching. It gains energy and electrons from oxidation of elemental sulfur and reduced inorganic sulfur compounds (RISCs) for carbon dioxide fixation and growth. Genomic analyses suggest that its sulfur oxidation system involves a truncated sulfur oxidation (Sox) system (omitting SoxCD), non-Sox sulfur oxidation system simila...

We use thermochemical equilibrium and kinetic calculations to model sulfur and phosphorus chemistry in the atmospheres of giant planets, brown dwarfs, low-mass stars, and extrasolar giant planets (EGPs). The chemical behavior of individual Sand P-bearing gases and condensates is determined as a function of pressure, temperature, and metallicity. Our results are independent of any particular mod...

Introduction: In our continuing effort to resolve and interpret the sulfur isotopic heterogeneity of meteorites[1-5], we analyzed a number of achondritic meteorites. Like oxygen, sulfur has more than two stable is otopes and therefore it is feasible to deconvolute the isotopic anomaly from the mass dependent isotopic fractionation that occurred during parent body processes . Any non-mass depend...

Photoelectron diffraction from the S 2p core level has been used to determine the adsorption site and orientation of sulfur and methyl thiolate (CH3S) on Ni(001) by comparing the experimental data with the results of multiple scattering calculations. The theory was initially checked for atomic S, which is known to adsorb in the four-fold hollow site on Ni(001), and the results corresponded to t...

Soybean (Glycine max L.) is considered as one of the major sources of oil and protein. In this study, the effects of vermicompost (VC) and sulfur (S) on soybean photosynthesis responses, yield, and grain quality were studied. To this end, a split-plot design field experiment based on randomized complete blocks with nine treatments and three replications was conducted in Aligudarz city Lorestan ...
