The sulfated glycosaminoglycans, such as keratan sulfate and chitin sulfate having 3-hydroxy free N-acetyl-beta-D-glucosaminyl residues as constituents, reacted with wheat germ agglutinin and Solanum tuberosum agglutinin by sugar-specific interaction. The glycosaminoglycans showed different inhibitory activities to the hemagglutination reaction of these lectins and keratan sulfate and its modif...

This study investigated the optimum mixture ratio of greenhouse tomato plant residues, wheat straw, and separated dairy manures for composting. Five 127-L laboratory-scale bioreactors were used to investigate the effect of separated dairy manure addition on the composting process of a tomato plant residues-wheat straw mixture. The wastes were mixed at 5 different ratios during the trials and we...

Background: Food safety has a direct impact on human health and as such is a growing concern worldwide. Presence of harmful pesticide residue in food is a serious cause for concern among consumers so it is important to monitor levels of pesticides in foods. The aim of this study was simultaneous determination of amounts of 58 pesticides in 40 wheat flour samples collected from the Tehran market...

Introduction Soil organic carbon (SOC) dynamic is one of the important factors that directly influence soil properties and quality. In agro-ecosystems, SOC dynamics are strongly linked to agricultural management practices. Methods this study, we investigated response its fractions various combination practices based on measurements obtained from an experiment conducted over four growing seasons...

A laboratory experiment was conducted to determine the allelopathic effect of residues aqueous extract of two ecotype of swallowwort (Cynanchum acutum L.) on germination traits of wheat (Triticum aestivum L.). A factorial experiment based on a completely randomized design with four replications was conducted at Islamic Azad University of Karaj in 2012. Factors were two swallowwort ecotype (Ghaz...

In order to investigate physiological and biochemical changes of wheat under stress residue of Imazethapyr herbicide (Imazethapyr), an experiment was conducted in a completely randomized design with four replications in greenhouse conditions at university of Mohaghegh Ardebili. The treatments consisted of five dose levels of herbicide Imazethapyr (0, 0.011, 0.022, 0.033 and 0.044 micrograms of ...

increasing resource use efficiency is one of the important ways to enhance agricultural productions and reduce environmental hazards. for this purpose, improvement of n use efficiency is an effective approach. nitrogen losses not only occur in field but also in the processing course. the objective of this study was to calculate nitrogen losses and efficiency during production to consumption for...

Using the cDNA clone for yeast TATA binding protein (TBP) (1) we have isolated a cDNA coding for wheat TBP from a wheat seedling cDNA library. Wheat TBP is 201 amino acids (wh, Figure 1). Comparison to other plant TBPs (Figure 1) indicates short, and moderately conserved, amino terminal domains. Dictyostelium also has a short amino domain, but it diverges from those of plants. In contrast the c...
