In silico evolution of diauxic growth [PDF]

open access: yes, 2015
The glucose effect is a well known phenomenon whereby cells, when presented with two different nutrients, show a diauxic growth pattern, i.e. an episode of exponential growth followed by a lag phase of reduced growth followed by a second phase of ...

Nitrogen, Phosphorus, and Potassium Uptake in Rain-Fed Corn as Affected by NPK Fertilization

open access: yesAgronomy, 2023
Effective nutrient management requires understanding nutrient uptake at various growth stages and nutrient removal by the harvested portion. Information on nutrient accumulation was provided by some older literature, and a few researchers have focused on

Nutrient Uptake Patterns in Forsythia [PDF]

open access: yesHortScience, 1996
Nutrient uptake and allocation patterns of Forsythia ovata × europaea `Meadowlark' grown in a recirculating hydroponic system in the greenhouse were observed for 5 months. Dormant rooted cuttings were placed in the system on 8 May 1995. The nutrient solution supplied (in mg·L–1) 100 N, 48 P, 210 K, 30 Mg, 60 Ca, 117 SO4, 3 Fe, 0.5 Mn, 0.15 Zn, 0.15 Cu,

A model for optimal mycorrhizal colonization along altitudinal gradients

open access: yesSilva Fennica, 2002
Mycorrhizal associations are generally favourable for vascular plants in nutrient-poor conditions. Still, non-mycorrhizal plants are common in high arctic and alpine areas, which are often poor in nitrogen and phosphorus.

Systems biology analysis of drivers underlying hallmarks of cancer cell metabolism. [PDF]

open access: yes, 2017
Malignant transformation is often accompanied by significant metabolic changes. To identify drivers underlying these changes, we calculated metabolic flux states for the NCI60 cell line collection and correlated the variance between metabolic states of ...

Nutrient uptake in tropical rivers receiving wastewater treatment plant discharge: High mass removal but low nutrient uptake efficiencies

open access: yesEcological Indicators, 2023
Wastewater treatment plants (WWTPs) have eliminated many problems related to sewage inputs to aquatic systems. However, the treated effluents still affect river and stream ecosystems.

Impact of planted hedgerow fallows on nutrient balances in a groundnut/maize/cassava intercrop [PDF]

open access: yes, 2019
To assess if the nutrient supply through planted tree fallows meets crop nutrient uptake and export, N, P, K, Ca and Mg uptake and export by a groundnut/maize/cassava intercrop was compared with the nutrient uptake by three planted fallow systems (Senna ...

Microalgae for municipal wastewater nutrient remediation: mechanisms, reactors and outlook for tertiary treatment [PDF]

open access: yes, 2015
This review explores the use of microalgae for nutrient removal in municipal wastewater treatment, considering recent improvements in the understanding of removal mechanisms and developments of both suspended and non-suspended systems.

Light is more important than nutrient ratios of fertilization for cymodocea nodosa seedling development [PDF]

open access: yes, 2018
Restoration of seagrass beds through seedlings is an alternative to the transplantation of adult plants that reduces the impact over donor areas and increases the genetic variability of restored meadows.

Time-dependent, species-specific effects of N:P stoichiometry on grassland plant growth [PDF]

open access: yes, 2010
N and P have different eutrophication effects on grassland communities, yet the underlying mechanisms are poorly understood. To examine plant growth in response to the varying (relative) supply of N and P, we conducted a two-year greenhouse experiment ...
