Removing top leaves increases yield and nutrient uptake in maize plants

open access: yes, 2020
Intraspecific competition for light affects nutrient uptake of maize, especially during the seed filling phase (from the blistering-stage to physiological-maturity).

Diel rhythmicity in amino acid uptake by Prochlorococcus [PDF]

open access: yes, 2008
The marine cyanobacterium Prochlorococcus, the most abundant phototrophic organism on Earth, numerically dominates the phytoplankton in nitrogen (N)-depleted oceanic gyres.

Plant growth-promoting rhizobacteria induce changes in Arabidopsis thaliana gene expression of nitrate and ammonium uptake genes

open access: yesJournal of Plant Interactions, 2019
Plant growth-promoting rhizobacteria (PGPR) enhance plant growth under the influence of multigenic processes, including nitrate ( ${\rm NO}_3^-$) and ammonium ( ${\rm NH}_4^ +$) uptake genes, which could potentially explain the improvement in plant ...

Effects of different phosphorus and potassium fertilization on contents and uptake of macronutrients (N, P, K, Ca, Mg) in winter wheat II Uptake of macronutrients [PDF]

open access: yesJournal of Central European Agriculture, 2014
The aim of this study was the assessment of macronutrient (N, P, K, Ca, Mg) accumulation in wheat at the critical phases of yield shaping as well as at the full ripening stage when judged at optimal P and K fertilizer rates applied as well as at reduced ...

Endocytotic uptake of nutrients in carnivorous plants [PDF]

open access: yesThe Plant Journal, 2012
SummaryCarnivorous plants trap, digest and absorb animals in order to supplement their mineral nutrition. Nutrients absorbed by the plant include different nitrogen species, phosphate, potassium, trace elements and small organic compounds. Uptake is usually thought to be performed via specific channels, but this study provides evidence that endocytosis

Nitrogen nutrition of harmful algal blooms in upwelling systems [PDF]

open access: yes, 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.

Comparing the Nutritional Needs of Two Solanaceae and One Cucurbitaceae Species Grown Hydroponically under the Same Cropping Conditions

open access: yesPlants, 2023
Switching over to closed-loop soilless culture systems, thus preventing pollution of water resources by nitrates and saving water and fertilizers, requires accurate estimations of the mean nutrient-to-water uptake ratios. To contribute to this objective,

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Modelling diverse root density dynamics and deep nitrogen uptake — a simple approach [PDF]

open access: yes, 2009
We present a 2-D model for simulation of root density and plant nitrogen (N) uptake for crops grown in agricultural systems, based on a modification of the root density equation originally proposed by Gerwitz and Page in J Appl Ecol 11:773–781, (1974). A
