Ecophysiology is a key discipline to identify and prioritize plant traits and associated processes that explain the variability of plant performance at different organizational levels (tissue, organ, plant, fields) and functional levels (biochemistry, physiology, growth and development...). Performance variability depends on the genotype, the environment and the cropping system (GxExC). because biological systems are highly context, their study implies the acquisition of massive and heterogeneous data, at different spatio-temporal scales, by implementing adapted phenotyping methodologies. The analysis of these data, in order to evaluate and predict the optimal combinations of traits and cultural practices in current or future agro-climatic scenarios, can only be done with the support of applied mathematics and computer science: modeling (statistical, mechanistic, predictive or explanatory) and modeling support tools, in particular software platforms and model exploration algorithms. It is in this context of research in plant ecophysiology and modeling that the PhenoMEN team (Phenotyping and Modeling of Plants in their Agro-climatic Environment) is working.
