Depletion of the heaviest stable N isotope is associated with NH4+/NH3 toxicity in NH4+-fed plants
(BioMed Central, 2011)
Artículo / Artikulua,
Background: In plants, nitrate (NO3-) nutrition gives rise to a natural N isotopic signature (δ15N), which correlates
with the δ15N of the N source. However, little is known about the relationship between the δ15N of the ...

The paper examines the moderating effect that the technological intensity of the environment in which the firm operates exerts in the High Performance Work Systems (HPWS) - firm's operational performance relationship. We ...
Leaf δ15N as a physiological indicator of the responsiveness of N2-fixing alfalfa plants to elevated CO2, temperature and low water availability
(Frontiers Media, 2015)
info:eu-repo/semantics/article,
The natural 15N/14N isotope composition (δ15N) of a tissue is a consequence of its N source and N physiological mechanisms in response to the environment. It could potentially be used as a tracer of N metabolism in plants ...
