Advanced Science, EarlyView.OsGSK2‐OsTCP19 module regulating nitrate response and lateral root (LR) development. Low‐nitrate condition results in reduced BR response, accumulation of OsGSK2 and phosphorylated OsTCP19, which suppresses the expression of nitrate‐responsive genes and LR‐development genes and impairs rice growth.

Comparison of 15N isotope methods to determine the recovery efficiency of nitrogen from green manure [PDF]
Pesquisa Agropecuária Brasileira, 2019 : The objective of this work was to compare three methods of 15N isotope application to the soil in order to determine the recovery efficiency of nitrogen derived from green manure by corn (Zea mays).

Isotopic fractionation of carbon, deuterium and nitrogen : a full chemical study
, 2015 Context. The increased sensitivity and high spectral resolution of millimeter telescopes allow the detection of an increasing number of isotopically substituted molecules in the interstellar medium. The 14N/ 15N ratio is difficult to measure directly for

Advanced Science, EarlyView.Inspired by Nitrite reductase, a metal–organic framework overlayer is introduced to regulate the interfacial hydration microenvironment on Cu electrodes, enriching hydrated K+ species that act as efficient proton donors. This strategy enables nitrate‐to‐ammonia conversion with near‐unity selectivity at industrial‐level current densities in neutral ...

Elastic and inelastic scattering of 15n ions by 11B at 84 MeV [PDF]
Ядерна фізика та енергетика, 2014 Angular distributions of the 11B + 15N elastic and inelastic scattering were measured at Elab (15N) = 84 MeV. The data were analyzed within the optical model and coupled-reaction-channels method.

Is there a niche complementarity for nitrate uptake among savannah shrub and tree species in a very deep Brazilian soil? [PDF]
, 2019 Belowground niche complementarity between deep-rooted and shallow-rooted species in mixed forests may result in a more complete exploitation of soil resources than in monocultures.

Confirmation of co-denitrification in grazed grassland [PDF]
, 2015 peer-reviewedPasture-based livestock systems are often associated with losses of reactive forms of nitrogen (N) to the environment. Research has focused on losses to air and water due to the health, economic and environmental impacts of reactive N.

Extremely low-frequency spectroscopy in low-field nuclear magnetic resonance
, 2009 We demonstrate a new phenomenon in nuclear magnetic resonance spectroscopy, in which nuclear spin transitions are induced by radio frequency irradiation at extremely low frequencies (of the order of a few Hz).
