Dynamics and Structure of Lipid Bodies DYSCOL 11 members 99 publications Most organisms store lipids or oils in intracellular organelles called lipid droplets (LD). Located at the crossroads of the accumulation, storage and mobilization of lipids, LDs have been the subject of few studies compared to the other important factors for lipid synthesis and mobilization.
Nitrogen Use, Transport and Signaling NUTS 14 members 102 publications The NUTS team studies nutrient signaling in plants with a particular emphasis on nitrogen signaling, nitrate transport and whole plant nitrogen management. Our main research interest is to investigate how plants orchestrate their response to changes in availability or demand of nutrients.
