Functional identification of bHLH transcription factor MdSAT1 in the ammonium response

open access: yesFruit Research, 2022
Plants mainly uptake inorganic nitrogen from soil as ammonium and nitrate. Less energy is required to assimilate ammonium compared to nitrates, and plants prefer to take up ammonium when the external nitrogen concentration is low.

Revisiting Why Plants Become N Deficient Under Elevated CO2: Importance to Meet N Demand Regardless of the Fed-Form

open access: yesFrontiers in Plant Science, 2021
An increase in plant biomass under elevated CO2 (eCO2) is usually lower than expected. N-deficiency induced by eCO2 is often considered to be a reason for this. Several hypotheses explain the induced N-deficiency: (1) eCO2 inhibits nitrate assimilation, (

Comparison of N2O Emissions From Cold Waterlogged and Normal Paddy Fields

open access: yesFrontiers in Environmental Science, 2021
Paddy fields are major sources of atmospheric N2O. Soil temperature and moisture strongly affect N2O emissions from rice fields. However, N2O emissions from cold-waterlogged paddy fields (CW), an important kind of paddy soil in China, are not well ...

Ammonium removal in granular activated carbon up-flow submerged reactors containing native bacterial consortium [PDF]

open access: yesJournal of Advances in Environmental Health Research, 2016
Free ammonium in industries wastewater could be one of the worst toxic contaminants of aquatic life if diluted in water. Biological nitrogen removal (BNR) is the most common method for removing ammonium and nitrate from wastewater.

The effect of inhibitors of plasma membrane H+ - ATPase and oxidoreductases on NH4+ uptake by Pisum arvense roots

open access: yesActa Societatis Botanicorum Poloniae, 2014
The effect of inhibitors of plasma membrane oxidoreductases (quinacrine and dicumarol) and H+-ATPase (dicyclohexylcarbodiimide and orthovanadate) on ammonium uptake by Pisum arvense seedlings and the activities of H+-ATPase and NADH-ferricyanide ...

Higher Tolerance of Canopy-Forming Potamogeton crispus Than Rosette-Forming Vallisneria natans to High Nitrogen Concentration as Evidenced From Experiments in 10 Ponds With Contrasting Nitrogen Levels

open access: yesFrontiers in Plant Science, 2018
Due to excess nutrient loading, loss of submersed macrophytes is a worldwide phenomenon in shallow lakes. Phosphorus is known to contribute significantly to macrophyte recession, but the role of nitrogen has received increasing attention.

Novel 3-Hydroxy-2-Naphthoate-Based Task-Specific Ionic Liquids for an Efficient Extraction of Heavy Metals

open access: yesFrontiers in Chemistry, 2018
Ionic liquids (ILs) are per definition salts with melting points below 100°C and might be green alternatives for the extraction of heavy metals from aqueous solutions due to their favorable environmental and physico-chemical properties.
