13. A rapid detection of multidrug-resistant Mycobacterium tuberculosis by a nitrate reductase assay on blood agar
The susceptibility of 49 Mycobacterium tuberculosis clinical isolates to isoniazid (INH) and rifampisin (RIF) (28 multi-drug resistant-tuberculosis samples) was determined by a nitrate reductase assay (NRA) on blood agar. Agreement between the NRA and other testing methods was found to be 93.8% for both INH and RIF. The sensitivity, specificity, positive pre

14. 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

15. Establishment of sensitive and resistant variety of tomato on the basis of photosynthesis and antioxidative enzymes in the presence of cobalt applied as shotgun approach
Cobalt (Co) affords both beneficial as well as toxic effects to plants. The present study was performed with an aim to find out the varietal differences among five tomato cultivars against the Co induced changes in growth, photosynthesis, nitrate reductase (E.C.1.6.6.1), carbonic anhydrase (E.C.4.2.1.1), antioxidative enzymes i.e. peroxidase (E.C.1.11.1.7),

16. Synergistic response of auxin and ethylene on physiology of Jatropha curcas L.
Jatropha curcas L. is a versatile crop since all its plant material is brought to use either as energy source, industrial or medicinal purpose. Several studies are ongoing in different parts of the world to optimize, enhance and exploit the growth, fruiting cycle and different developmental stages of the plant so that the economic yield of the plants can be

17. Thiamethoxan on sugar cane, common bean, soybean, citrus and coffee plants: parameters of development and biochemical aspects / Tiametoxam em plantas de cana-de-açúcar, feijoeiro, soja, laranjeira e cafeeiro: parâmetros de desenvolvimento e aspectos bioquímicos
Insecticides and fungicides are often studied to their efficiency in controlling pests and diseases, however can cause physiological effects little known that can affect crop growth. Thiamethoxan is a systemic insecticide from the neonicotinoid group, nitroguanidine family, which acts on nicotinic acetylcholine receptor of insects, damaging their nervous sys

18. Indução termoperiódica da nitrato redutase de membrana plasmática em abacaxizeiro (Ananas comosus) / Thermoperiodic induction of nitrate reductase associated with the plasma membrane in pineapple (Ananas comosus)
A nitrato redutase (NR) atua juntamente com a nitrito redutase (NiR) catalisando a primeira etapa da redução do nitrato. A NR, no citossol, é ativada, principalmente, pela luz e reduz o nitrato a nitrito. Em seguida, este é reduzido a amônio. Trabalhos anteriores demonstraram que a isoforma citossólica da NR está presente nas folhas e raízes do abaca

19. The contribution of genes required for anaerobic respiration to the virulence of Salmonella enterica serovar Gallinarum for chickens
Salmonella enterica serovar Gallinarum (SG) is an intracellular pathogen of chickens. To survive, to invade and to multiply in the intestinal tract and intracellularly it depends on its ability to produce energy in anaerobic conditions. The fumarate reductase (frdABCD), dimethyl sulfoxide (DMSO)-trimethylamine N-oxide (TMAO) reductase (dmsABC), and nitrate r

20. Suprimento de nitrogênio e de potássio e características morfogênicas, nutricionais e produtivas do capim-Marandu / Nitrogen and potassium supply and the morphogenetic, nutritional and productive characteristics of Marandu palisadegrass
Nitrogen and potassium are essentials for plant development, are extracted by plants in high amounts and their availabilities may change the morphogenetic, productive and nutritional characteristics of plants. The objectives of this research were: a) to assess fertilization with nitrogen and potassium rates on morphogenetic and shoot and root dry matter prod

21. ATIVIDADE DA ENZIMA REDUTASE DE NITRATO EM TRÊS ESPÉCIES DE CAMPOS FERRUGINOSOS (CANGA) RESPONDE A FERTILIZAÇÃO NITROGENADA
Human activities have increased considerably the input of nitrogen in soils of agricultural and natural systems, may cause profound changes in physiology, morphology and ecology of plants. In this context, the activity of nitrate reductase (NR) becomes an important tool for understanding plant responses to increased N availability in soils through atmospheri

22. Growth of Indian mustard (Brassica juncea L.) in response to salicylic acid under high-temperature stress
Pots holding 7 day-old seedlings of Indian mustard (Brassica juncea L.) were subjected to differential temperature stress by exposing plants to 30 or 40ºC for 24 h. Seedlings were sprayed with double distilled water (DDW) or 10-5M salicylic acid (SA) at the 8-day stage and were sampled at 30 DAS. The plants exposed to temperature stress exhibited a signific

The nitrogen and sulphur availability in soil might influence plant growth, affecting the vegetal production. The objectives of this work were: a) to assess fertilization with nitrogen and sulphur rates on yield of Brachiaria brizantha cv. Marandu (Marandu palisadegrass) under establishment in a soil supporting degrading pasture of Brachiaria decumbens (Sign

24. 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
