Abscisic acid (ABA) is a well-studied phytohormone known to be involved in sub-sets of stress responses in plants, such as iron (Fe) deficiency and phosphorus (P) deficiency in Arabidopsis. However, whether ABA is...

Modelling individual kernel filling-processes with source–sink interactions
Failure to account for the variation of kernel growth may cause serious deviations in the simulation of crop yield. Ma et al. built a GREENLAB-Maize-Kernel model to incorporate source-sink limited allocation approach to...
Ethylene affects cell wall remobilisation
Seeking to uncover the effects of ethylene on the metabolic process and pectin remobilising capacity of rice (Oryza sativa) that is grown in phosphorus (P)-deficient conditions, Zhu et al. find that ethylene positively...
Fast-growing trees rely on reserves for new spring growth
Uscola et al. use isotope labeling to study carbon and nitrogen movements in new spring growth in seedlings of 4 coexisting Mediterranean evergreen trees.
Downregulation of net phosphorus uptake vs. leaf resorption
A trade-off may exist between the capacity of plants to downregulate their phosphorus uptake capacity and the efficiency of resorption from leaves in severely impoverished environments.
Simulating nitrogen economy of wheat plants
The model NEMA (Nitrogen Economy Model within plant Architecture) simulates nitrogen fluxes within a wheat plant (Triticum aestivum) after flowering. Bertheloot et al. show that the model is able to predict the time...
Process-based model of N uptake and use in wheat
Defining strategies for better use of nitrogen by crops requires sufficiently mechanistic models of nitrogen acquisition and use by plants. Bertheloot et al. describe the model NEMA (Nitrogen Economy Model within plant...
