Circadian rhythms, with a period close to 24h, are observed in most living organisms and play a fundamental role in the adaptation
of these organisms to their environment. Recently, remarkable advances have permitted to largely unravel the molecular bases of
circadian rhythms in plants. Computational models were thus developped in order to analyze and clarify the regulatory network at
the origin of these rhythms. We investigate by means of such models the effect of nutrition, and more particularly magnesium
depletion, on the circadian rhythms of Arabidopsis. This study is based on computational approaches (in our Unit) combined with
experimental approaches (in the Laboratory of Physiology and Molecular Genetics of Plants, ULB). This collaborative project pertains to the
ARC (Action de Recherche Concertée) 2012-2017 « Nutrition and circadian rhythms in plants »
(http://www.ulb.ac.be/recherche/presentation/fr-arcleloup.html).
