Diel rhythmicity in amino acid uptake by Prochlorococcus [PDF]
, 2008 The marine cyanobacterium Prochlorococcus, the most abundant phototrophic organism on Earth, numerically dominates the phytoplankton in nitrogen (N)-depleted oceanic gyres.

Advances in understanding of nitrogen (N) uptake by plant roots
, 2021 Efficient use of nitrogen (N) by plants and particularly crops, is of global importance. In agriculture, high crop yields and protein content depend upon extensive N-inputs, however fertilizer N is costly to the farmer, and overuse can be damaging to the

Amino acid uptake in Arabidopsis [PDF]
, 2008 Nitrogen (N) is essential for all living organisms and is considered to be the limiting factor for plant growth in many ecosystems. Although generally believed to rely on mineral N to fulfill their N needs, plants have also been found to access organic N

Assessment of nitrogen uptake and biological nitrogen fixation responses of soybean to nitrogen fertiliser with SPACSYS [PDF]
, 2020 Chemical fertiliser nitrogen addition will inhibit biological nitrogen fixation (BNF) for soybean (Glycine max [L.] Merr) growth. The optimal balance of these two nitrogen input sources has been a key issue for sustainable development in Northeast China.

Nitrogen nutrition of harmful algal blooms in upwelling systems [PDF]
, 2009 Blooms of toxic, or otherwise harmful phytoplankton species are known to occur in eastern boundary upwelling systems, coincident with the relaxation of upwelling in latesummer/autumn.

Frontiers in Marine Science, 2016 Bulk measurements can be made of phytoplankton standing stocks on a quasi-synoptic scale but it is more difficult to measure rates of production and nutrient uptake. We present a method to estimate nitrogen uptake rates in productive coastal environments.

Nitrogen Uptake by Citrus Leaves [PDF]
Journal of the American Society for Horticultural Science, 1995 We studied whether foliar-applied N uptake from a single application of low-biuret N-urea or K NO to citrus leaves was affected by N source, leaf age, or whole-shoot N content. In a glasshouse experiment using potted 18-month-old Citrus paradisi (L.) `Redblush' grapefruit trees grown in full ...

Global terrestrial nitrogen uptake and nitrogen use efficiency
Journal of Ecology, 2022 Abstract Plant biomass production (BP), nitrogen uptake ( N up ) and their ratio, nitrogen use efficiency (NUE), must be quantified to understand how nitrogen (N) cycling constrains terrestrial carbon (C) uptake. But the controls of key plant processes determining

Derivation of a dynamic model of the kinetics of nitrogen uptake throughout the growth of lettuce : calibration and validation [PDF]
A kinetic model of nitrogen (N) uptake throughout growth was developed for lettuce cultivated in nutrient solution under varying natural light conditions.
