The missing link of the chemiosmotic theory

An international collaboration has enabled researchers at the Cell & Plant Physiology Laboratory to highlight the action of the TPK3 potassium channel on the use of light by the electron transfer, and thus the survivability of the plant.

Photoprotection in microalgae

Researchers at the Plant & Cellular Physiology laboratory study the molecular strategies developed by microalgae​ that allow them to have a selective growth advantage in low light conditions. This study suggests ways to improve their growth in the case of future applications in biotechnology.​ References Allorent G, Tokutsu R, Roach T, Peers G, Cardol P, Girard-Bascou J, Seigneurin-Berny D, Petroutsos D, Kuntz M, Breyton C, Franck F, Wollman FA, Niyogi KK, Krieger-Liszkay A, Minagawa J and Finazzi G A dual strategy to cope with high light in Chlamydomonas reinhardtii.

Genomic insights into photosynthesis in eukaryotic phytoplankton

Researchers at the Cell & Plant Physiology laboratory decided to explore the role of state transitions on photosynthesis in Chlamydomonas mutants with respiratory defects. The analysis of these mutants has allowed them to show the essential role of the role of state transitions on photosynthesis of the green alga Chlamydomonas.
