1. Nitrate Reductase Activity and Nitrogen and Biomass Accumulation in Sugarcane under Molybdenum and Nitrogen Fertilization
ABSTRACT Prior research on sugarcane showed increment of productivity following molybdenum (Mo) fertilization and some indication of the potential role either on nitrate reductase activity (NRA). However, this increment can depend on sugarcane variety and nitrogen (N) fertilization. This study aimed to evaluate the effect of Mo fertilization on Mo uptake, on

2. PERCOLATE QUALITY IN SOIL CULTIVATED WITH APPLICATION OF WASTEWATER FROM SWINE SLAUGHTERHOUSE AND DAIRY PRODUCTS
ABSTRACT The objective of this study was to evaluate the quality of the percolate in soil columns cultivated with Tiffon-grass 85 under different wastewater rates from swine slaughterhouse and dairy. The experiment was conducted at the Department of Engineering at the Federal University of Lavras, in PVC columns with 0.30 m of diameter and 1.2 m deep, filled

3. Comparação genotípica e fenotípica de diferentes isolados clínicos e ambientais de Rhodotorula spp. / Genotypic and phenotypic comparisons among clinical and environmental isolates of Rhodotorula spp.
Introduction: Rhodotorula spp. are yeasts widely distributed in the environment and can colonize the human body at different anatomical locations. This emerging pathogen is capable of causing superficial and invasive infections in humans whereas bloodstream infection is the most commonly described in the literature. Mainly three species have been related to

4. Limnological aspects of Little AÃudagem in Semiarid: Case Study of Dams Settlement May 25, Ce-Madalena / Aspectos limnolÃgicos da pequena aÃudagem no semiÃrido: estudo de caso dos aÃudes do Assentamento 25 de Maio, Madalena-Ce
The studies for small reservoirs in the semiarid northeast are still scarce, mainly in relation to water quality. This research aimed to discover the dynamic processes that occur in small reservoirs, to evaluate the multiple uses, the trophic state and water quality in small reservoirs representing the settlement on May 25. Carried out the systematic monitor

5. Nitrate reductase activity in field-grown pueraria lobata (Kudzu) in southeastern Brazil.
Although Pueraria lobata (Willd.) Ohwi (P. thunbergiana) (Sieb. & Zucc.) Benth.) is thus ecologically and economically important in much to world, its physiological ecology and other factor contributing to its invasive growth are not well understood. Nitrate reductase activity (NRA) measurements have long been used to indicate the effect of changes in the en

7. Isolation and growth characterization of chlorate and/or bromate resistant mutants generated by spontaneous and induced foreword mutations at several gene loci in Aspergillus niger
We aimed her mainly to evaluate the contribution of newly employed bromate selection system, in obtaining new Aspergillus niger nitrate/nitrite assimilation defective mutants, through Ultraviolet treatment (UV), 1, 2, 7, 8-Diepoxyoctane (DEO), phenols mixture (Phx)) and spontaneous treatments. The newly employed bromate selection system was able to specify o

8. Evaluation of physiological effect of fungicides on soybean crop / Avaliação do efeito fisiológico do uso de fungicidas na cultura de soja
The use of products with tonic action in plants has stimulated research in different areas of agriculture, where the use of fungicides with physiological effect became important. One of the most promising is the strobilurin Pyraclostrobin, that in addition to the fungicidal action has caused an increase in productivity attributed to the physiological effects

9. Absorção e assimilação dos íons amônio e nitrato e os seus efeitos sobre o crescimento e desenvolvimento de cevada e arroz em solução nutritiva / Ammonium and nitrate absorption and assimilation and their effects on growth and development of barley and rice in nutrient solution
A disponibilidade dos íons + 4 NH e - 3 NO em concentrações e proporções desbalanceadas entre si no solo pode interferir na absorção e assimilação do N de forma distinta entre plantas alterando o seu crescimento e desenvolvimento. O presente trabalho objetivou caracterizar esta dinâmica do N pelas culturas de arroz e de cevada supridas com distinta

10. The role of nitrate reductase and asparagine synthetase in soybean (Glycine max L.) under nitrogen stress / Papel da redutase do nitrato e da asparagina sintetase em plantas de soja (Glycine max L.) sob condições de estresse de nitrogenio
The root system of soybean (Glycine max L.) is an important site for the assimilation of nitrogen, whether by nitrate assimilation in the roots, or by symbiotic nitrogen fixation in the nodules. The main products of inorganic nitrogen assimilation, the amino acids asparagine and glutamine and the ureides allantoin and allantoic acid, are used in the transpor

11. Nitrogen assimilation in Citrus based on CitEST data mining
Assimilation of nitrate and ammonium are vital procedures for plant development and growth. From these primary paths of inorganic nitrogen assimilation, this metabolism integrates diverse paths for biosynthesis of macromolecules, such as amino acids and nucleotides, and the central intermediate metabolism, like carbon metabolism and photorespiration. This pa
