Diatoms and light

Researchers at the Cell & Plant Physiology laboratory have identified a key component of the photo-accli​mation mechanisms of a diatom that allows it to acclimate to changes in its environmental conditions, especially fluctuations of the light intensity.

Draw inspiration from plants to better control our energy and material flows

Living organisms have developed regulatory systems of their metabolic pathways, which they need to survive. Why not learn from these mechanisms to improve our control of material flow and energy ? It is in this context that researchers from CNRS, INRA and CEA have developed a mathematical model representing the amino acid biosynthetic pathways in the plant Arabidopsis. This model was used to reproduce the measurements made with whole plants, thus demonstrating its accuracy. Simulations were then allowed to qualitatively and quantitatively understand the operation of such a control network. References Curien G, Bastien O, Robert-Genthon M, Cornish-Bowden A, Cárdenas […]

An original adaptation of photosynthesis in the marine green alga Ostreococcus

The analysis of the adaptation of different ecotypes of Ostreococcus (a green line picoeucaryote) belonging to two different ecological niches both in their nutrient content (Fe) and light gave unexpected results.​ References Cardol P, Bailleul B, Rappaport F, Derelle E, Béal D, Breyton C, Bailey S, Wollman FA, Grossman A, Moreau H and Finazzi G An original adaptation of photosynthesis in the marine green alga Ostreococcus.
