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.

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 ...

Tracking nitrogen losses in a greenhouse crop rotation experiment in North China using the EU-Rotate_N simulation model [PDF]
, 2010 Vegetable production in China is associated with high inputs of nitrogen, posing a risk of losses to the environment. Organic matter mineralisation is a considerable source of nitrogen (N) which is hard to quantify.

Soil nitrogen dynamics regulate differential nitrogen uptake between rice and upland crops
Journal of Integrative AgricultureNitrogen use efficiency in rice is lower than in upland crops, likely due to differences in soil nitrogen dynamics and crop nitrogen preferences. However, the specific nitrogen dynamics in paddy and upland systems and their impact on crop nitrogen uptake

New Phytologist, 2019 •Plant-microbial interactions in the rhizosphere are an essential link in soil nitrogen cycling and plant nitrogen supply. Plant phenotype and genotype interact with the soil environment to determine rhizosphere community structure and activity. However,

pH‐mediated activation of the lysosomal arginine sensor SLC38A9
FEBS Letters, EarlyView.Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

The Dynamic of Nitrogen Uptake from Different Sources by Pea (Pisum sativum L.)
Agriculture, 2021 Nitrogen uptake from various sources by plants capable of biological reduction of N2 in symbiotic systems with root nodule bacteria is influenced by many factors.

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
