The effect of nitrate assimilation deficiency on the carbon and nitrogen status of Arabidopsis thaliana plants
(Springer WienWienAustria, 2014)
Water deficit modifies the carbon isotopic composition of lipids, soluble sugars and leaves of Copaifera langsdorffii Desf. (Fabaceae)
(Soc Botanica Brasil, 2018-01-01)
Water deficit is most frequent in forest physiognomies subjected to climate change. As a consequence, several tree species alter tissue water potential, gas exchange and production of carbon compounds to overcome damage ...
Measured and modeled interactive effects of potassium deficiency and water deficit on gross primary productivity and light-use efficiency in Eucalyptus grandis plantations
Global climate change is expected to increase the length of drought periods in many tropical regions. Although large amounts of potassium (K) are applied in tropical crops and planted forests, little is known about the ...
Phosphatidylinositol phospholipase C mediates carbon sensing and vegetative nuclear duplication rates in Aspergillus nidulans
(CANADIAN SCIENCE PUBLISHING, NRC RESEARCH PRESS, 2011)
In this work, we disrupted one of three putative phosphatidylinositol phospholipase C genes of Aspergillus nidulans and studied its effect on carbon source sensing linked to vegetative mitotic nuclear division. We showed ...
Lanthanum carbonate, like sevelamer-HCl, retards the progression of vascular calcification and atherosclerosis in uremic apolipoprotein E-deficient mice
(OXFORD UNIV PRESSOXFORD, 2012)
Atherosclerosis and vascular calcification (VC) progression in chronic kidney disease is favored by disturbances of mineral metabolism. We compared the effect of phosphate binder lanthanum (La) carbonate with sevelamer-HCl ...
Carbon dioxide gas sensing properties of ordered oxygen deficient perovskite LnBaCo2O5+ı(Ln = La, Eu)
Polycrystalline samples of layered cobaltites LnBaCo2O5+ı(Ln = La, Eu) were synthesized by standardsolid state reaction. Structural, magnetic and carbon dioxide gas sensing properties of the samples werecarefully investigated. ...
Dietary lysine deficiency increases the incorporation rate of nitrogen-free compounds in muscle of pacu (Piaractus mesopotamicus)
Isotopic experiments are conducted to evaluate turnover rates in fish tissue, especially as a function of nutrition. In 2007, Cerling et al. proposed an approach they named the reaction progress variable, which among other ...
