Light- and cold dependent integrators of chloroplast gene expression and C-metabolism in Chlamydomonas
Based on our studies of two chloroplast integrators in Chlamydomonas reinhardtii, i.e., the NADPH-dependent thioredoxin reductase C (NTRC) and the DLA2 (E2) subunit of the chloroplast pyruvate dehydrogenase complex (cpPDC), we aim at elucidating in particular the role of NTRC for cold acclimation by analysing its functional interplay with identified interaction partners like CP12, Cr-NEET as well as DLA2. We will apply state-of-the-art genetic, biochemical and imaging techniques for dismantling NTRC´s molecular working and the spatial organization of the underlying regulatory system.
