MarkProfessor Mark Stitt Mark is a Department Director at the MPIMPP. His research addresses the regulation of central metabolic pathways in plants, especially photosynthesis, starch and sucrose metabolism. His interest in C4 metabolism started when he developed methods to measure metabolite concentration gradients between mesophyll and bundle sheath cells. He has recently refined methods to use stable isotope labeling and liquid chromatography linked with tandem mass spectrometry in order to gain deeper insights into the path of carbon in both C3 and C4 photosynthesis.

John Lunn photoDr John Lunn John is a Senior Research Scientist at MPIMPP. He has a long-standing interest in understanding how plants determine the fate of carbon fixed during photosynthesis. His current work focuses on a sugar-signalling metabolite, trehalose 6-phosphate. Forward and reverse genetic approaches are combined with transcript, protein and metabolite analyses to identify components of sugar-signalling pathways, with the long term goal of understanding carbon allocation at the whole-plant level and how to engineer this for improvements in crop yields. 


Dr. Stéphanie Arrivault Stéphanie is currently a postdoc in Mark Stitt´s lab. She gained her PhD in plant molecular biology from the MPIMP where she studied the role of a putative metal transport protein in Arabidopsis. Her research is focused on the elucidation of carbon fluxes in C3 and C4 photosynthesis by use of dynamic 13CO2 labeling coupled with LC-MS/MS quantification.



Gian Luca Borghi

Gian Luca Borghi  Gian Luca is currently a PhD student at the Max Planck Institute for Molecular Plant Physiology, under the supervision of Stéphanie Arrivault, John Lunn and Mark Stitt. He graduated in Biotechnology (BSc) from the University of Parma (Italy), and in Molecular and Cellular Biology (MSc) from the University of Bologna (Italy), with both thesis projects focusing on plant biology. Thanks to a LLP Leonardo Unipharma Graduates fellowship, he spent 6 months at Plant Research International, Wageningen (The Netherlands), working on alternative splicing in Arabidopsis. His contribution to the C4-rice project will be centered around the elucidation of carbon fluxes in transgenic rice lines with emphasis on C4 photosynthesis by use of dynamic 13CO2 labeling coupled with LC-MS/MS quantification.
