Urea as an Effective Nitrogen Source for Cyanobacteria
… with urea now accounting for > 50% of nitrogen fertilizer applications worldwide. The shift from inorganic nitrogen fertilizers to urea-based sources has coincided with the reappearance of cyanobacteria blooms in freshwaters. Here, we examined urea as a nitrogen source for three …

Integrating nitrogen source and application timing into the management of large patch on zoysiagrass
… patch disease outbreaks, specifically related to nitrogen applications. The first goal of this research was to evaluate nitrogen source impacts on the growth, morphology, and infection potential of the causal pathogen Rhizoctonia solani AG 2-2 LP. The second goal was to determine how specific …

Effects of nitrogen source and level on the growth and composition of Sinningia speciosa Lodd
… modified Hoagland's solutions in which the N source and level were varied. Shoot dry weight of gloxinias grown in an organic medium in the winter was lower with 100% NH₄ than with 100% NO₃ but was unaffected by N level, while in the fall shoot dry weight was lower with 100% NH₄ than with 0 or …

Partitioning and Utilization of Apparent Photosynthate by Soybean (Glycine Max (L.) Merr.) Relative to Nitrogen Source: Nitrogen vs Nitrate
… of NO(,3)('-) respectively serving as sole source of nitrogen. Plants were evaluated on the basis of whole plant efficiency of apparent photosynthate utilization relative to nitrogen assimilation (expressed as the ratio of moles of carbon respired by the whole plant to the moles of nitrogen …

Influence of nitrogen source and metalaxyl on nitrification in soils and the yield and quality of flue-cured tobacco
… on the + nitrification of NH₄⁺ from various sources; 2) study the Influence of soil pH on inhibition of nitrification by metalaxyl; 3) study the Influence of N source and metalaxyl on N accumulation in the plant; and 4) evaluate the influence of N source and metalaxyl on the yield, quality, …

Regulation of GAP1 permease sorting in Saccharomyces cerevisiae
… of Saccharomyces cerevisiae is regulated by the nitrogen source in the growth medium. During growth on a non-preferred nitrogen source or during nitrogen starvation, Gaplp is sorted to the plasma membrane, where it is active and can transport amino acids into the cell. During growth on a …

Nitrate- and Nitrite-Reductase Activities in Mycobacterium Avium A5
… A5 cells were grown in a defined minimal medium (Nitrogen Test Medium) with glutamine, nitrite, nitrate, or ammonia as sole nitrogen source at a concentration of 2 mM at 370C aerobically. The strain grew well on all the nitrogen sources except nitrite. It grew slowly on nitrite with a generation …

Influence of Dietary Arginine Deficiency and Increased Nitrogen Metabolism on the Induction of Orotic Aciduria
… and minced spleen when ammonia was used as a nitrogen source. The order of orotate biosynthesis from ('14)C-bicarbonate was liver > spleen > kidney > muscle > heart. Arginine deficiency resulted in a significant stimulation of liver orotic acid biosynthesis. Orotic acid synthesis from spleens …

Development and Study of Atomic Nitrogen Sources for Synthesis of Electronic Materials
Low-pressure atomic nitrogen source was used to investigate nitridation of thin silicon dioxide films at 760°C. The SiO2 films were substantially nitrided by an exposure to the atomic flux of ∼10 15 cm-2s-1 for only 30 s.

Nitrogen regulation of theput operon in enteric bacteria
Enteric bacteria can grow on proline as the sole nitrogen and carbon source. Expression of the proline utilization (put) operon in Klebsiella aerogenes and Escherichia coli is responsive to nitrogen regulation, but Salmonella typhimurium can not activate put operon expression when growing in medium …

Peroxidase, Protein, and Growth Responses of Cultured Tomato Pith Explants
… synthesis, the presence of a carbon-energy source, aerobic conditions, and calcium are required for induction and increases in soluble peroxidase. Although induction had been demonstrated previously without an exogenous nitrogen source, quantitative changes in protein were related to the …

Derivation of interspecific Solanum hybrid genotypes with resistance to Colorado potato beetle (Leptinotarsa decemlineata Say)
… cultured to observe the effects of reduced nitrogen source on androgenesis. Anthers were distributed to five reduced nitrogen sources. The N concentration was 30 mM. No tested reduced nitrogen source proved superior to the control. Genotype significantly affected embryo production. Eleven …

Metabolism, nutritional effects, and mutagenesis of crystal violet decolorization by a biofungicide agent Pseudomonas putida strain M-17
… of ammonia, nitrate or urea for the amino acid nitrogen source. However, a different medium containing succinic acid and using ammonia as the sole nitrogen source was found to induce the reaction. Factors that did not affect the decolorization reaction included temperature (14-30° C) and pH …

Purine Degradation and Ureide Catabolism by Soybean (Glycine Max (L.) Merrill); Cell Suspension Cultures
… phosphate (IMP), as sole nitrogen sources. The inhibitors of purine degradation, allantoxanamide and allopurinol, caused accumulation of uric acid and hypoxanthine, respectively, in cell suspensions fed radiolabelled IMP and effectively blocked growth on IMP, but not …
