    Multiple mechanisms of nitrate sensing by Arabidopsis nitrate transceptor NRT1.1

    In Arabidopsis the plasma membrane nitrate transceptor (transporter/receptor) NRT1.1 governs many physiological and developmental responses to nitrate. Alongside facilitating nitrate uptake, NRT1.1 regulates the ...

    Characterization and regulation of ammonium transport systems in Citrus plants

    We have investigated both the kinetics and regulation of 15NH4 + influx in roots of 3-month-old hydroponically grown Citrus (Citrus sinensis L. Osbeck × Poncirus trifoliata Blanco) seedli...

    The Rhizobium meliloti PII Protein Affects Alfalfa Nodule Development and Mobilisation of Fixed Nitrogen

    Differentiation of Rhizobium into nitrogen fixing bacteroids implies a shift in nitrogen metabolism from a non nitrogen-fixing, ammonium assimilation state, to a nitrogen-fixing, ammonium exporting state in which...

    Critical evaluation of thein situ nitrate reductase assay

    Anin situ method, derived from anin vivo method, was used to determine nitrate reductase activity (NRA) in:i) excised barley and corn shoots and excised soybean leaves during a N-depletion experiment and; ii) roo...

    In situ nitrate reductase activity as an indicator of nitrate availability

    The effect of external nitrate concentration in the nutrient solution on nitrate reduction by 7-day-old barley seedlings was investigated using anin situ nitrate reductase activity (NRA) assay, performed with or ...

    Root contribution to nitrate reduction in barley seedlings (Hordeum vulgare L.)

    The leaf and root nitrate reductase activities were measured in 7 day-old barley seedlings by anoxic nitrite accumulation in darkness, during 48h after the transfer from a N-starved medium to a 1.5 mM K15NO3 medi...
