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 ...
Comparison of four functionalization methods of gold nanoparticles for enhancing the enzyme-linked immunosorbent assay (ELISA)
(Beilstein-Institut, 2017)
info:eu-repo/semantics/article,
The enzyme-linked immunosorbent assay (ELISA) technique is based on the specific recognition ability of the molecular structure
of an antigen (epitope) by an antibody and is likely the most important diagnostic technique ...
Mechanisms of ammonium toxicity and the quest for tolerance
(Elsevier, 2016)
Artículo / Artikulua,
Ammonium sensitivity of plants is a worldwide problem, constraining crop production. Prolonged application of ammonium as the sole nitrogen source may result in physiological and morphological disorders that lead to decreased ...
Both free indole-3-acetic acid and photosynthetic performance are important players in the response of Medicago truncatula to urea and ammonium nutrition under axenic conditions
(Frontiers Media, 2016)
info:eu-repo/semantics/article,
We aimed to identify the early stress response and plant performance of Medicago truncatula growing in axenic medium with ammonium or urea as the sole source of nitrogen, with respect to nitrate-based nutrition. Biomass ...
Rice (Oryza) hemoglobins [version 2; peer review: 2 approved]
(F1000 Research, 2014)
info:eu-repo/semantics/article,
Hemoglobins (Hbs) corresponding to non-symbiotic (nsHb) and truncated (tHb) Hbs have been identified in rice (Oryza). This review discusses the major findings from the current studies on rice Hbs. At the molecular level, ...
Evaluation of the anti-nitrative effect of plant antioxidants using a cowpea Fe-superoxide dismutase as a target
(Elsevier, 2014)
info:eu-repo/semantics/article,
Nitric oxide cytotoxicity arises from its rapid conversion to peroxynitrite (ONOO) in the presence of superoxide, provoking functional changes in proteins by nitration of tyrosine residues. The physiological significance ...
Nitric oxide induces the alternative oxidase pathway in Arabidopsis seedlings deprived of inorganic phosphate
(Oxford University Press, 2015)
info:eu-repo/semantics/article,
Phosphate starvation compromises electron flow through the cytochrome pathway of the mitochondrial electron transport chain, and plants commonly respond to phosphate deprivation by increasing flow through the alternative ...
