Dr Stéphanie Arrivault is a science researcher at the Max Planck Institute for Molecular Plant Physiology in Potsdam. Her research is focused on the Calvin-Benson cycle, using LC-MS/MS quantification of metabolites to study regulation and interspecies diversity and, in combination with dynamic 13CO2 labelling to elucidate fluxes in C3 and C4 photosynthesis. Stéphanie is also involved in the C4 Rice project.
Title: Targeted metabolite profiling as a top-notch approach to uncover inter-species diversity in the Calvin-Benson cycle
Webinar date: Tuesday 1st March 2022 14.00 CET
Abstract: The Calvin-Benson cycle (CBC) evolved over 4 billion years ago and there is evidence for variation in how the CBC operates (for example between photosynthetic organisms that do and don´t have a CO2 concentration mechanism, CCM). While most studies of CBC diversity have focused on single aspects such as Rubisco kinetics and regulation, we are using quantitative CBC metabolite analyses as a broader strategy to uncover diversity in CBC operation. This approach has been applied to several C3 and C4 species, to a range of C3 to C4 Flaveria species and to single cells with a CCM such as algae and cyanobacteria.
