Prof. Dr. Mark Stitt

Director of Department 2: Metabolic Networks, and Leader of the Research Group “System Regulation” at the Max Planck Institute of Molecular Plant Physiology, Germany.

Mark Stitt earnt the Ph.D. in 1978, and completed his postdoctoral training at the Institute for Physiological Chemistry and Physical Biochemistry, Munich, followed by research experiences at UC Berkeley, and his habilitation in Plant Biochemistry at the University of Göttingen. Dr. Stitt was appointed Professor for Plant Biochemistry in the Department of Plant Physiology, Bayreuth in 1986 and became Professor and Head of the Institute for Botany, University of Heidelberg in 1991.  From 1997 to 2000 he served as the Dean of the Faculty of Biology at the University of Heidelberg, and in 2000 was appointed as the Director of the department ‘Metabolic Networks’ at the Max-Planck Institute for Molecular Plant Physiology in Golm. 

Professor Stitt has been a Handling Editor for Plant Cell and Environment since 1992, and for The Plant Journal since 1996.  He is Section Head for Plant Biochemistry and Physiology for Faculty of 1000 (2000), and is on the Advisory Board for an additional four scientific journals including Current Opinion in Plant Biology. He also serves on the Advisory Boards and Steering Committees of an   additional nine European and international scientific institutes and collaborative research projects. 

In 1986 Dr. Stitt was awarded the Presidents Medal of the Society for Experimental Botany, England, and in 2002 was identified by ISI as a Highly Cited Researcher, based upon his publications from 1991 to 2001. Overall, Dr. Stitt has over 400 peer-reviewed publications to his credit. His work is focused on deciphering the regulation and networking of biochemical metabolic pathways, for what he carries out comparative genetic and reverse genetic studies on ecotype variants, mutants and transgenic plants.

The diel light-dark cycle is one of the most pervasive environmental changes with which plants have to cope. Growth at night depend on reserves that are accumulated in preceding light periods. Arabidopsis transiently accumulates up to 60% of its fixed carbon as starch, which during the night is remobilized in a near-linear manner such that it is almost but not totally exhausted at the next dawn. This pattern of diel starch turnover is crucial for optimal growth in carbon-limiting conditions, and is robust against fluctuations in the environment.

His robustness reflects the sophisticated regulation of starch accumulation and mobilization, which is itself closely intermeshed with the diel regulation of growth. In conditions where less carbon is fixed per 24 h cycle (for example short photoperiods, low light. plants accumulate a larger proportion of their fixed carbon as starch. Allocation to starch is regulated by multiple pathways that integrate information about predictable (e.g. photoperiod duration) and unpredictable (e.g. irradiance received in a given 24 h cycle) environmental variables. At night, the circadian clock paces starch mobilization to ensure that starch is almost but not totally exhausted at dawn. When more carbon is available than is used for growth during the night, the sucrose signal trehalose 6-phosphate slows down starch degradation.

Almost all experimental studies of metabolism and growth are performed in recurring square-wave light regimes (i.e. the same light intensity every day, suddenly turning it on and off). These are artificial conditions. In the field, irradiance increases gradually at dawn, decreases gradually at dusk, and fluctuates unpredictably within and between days. I will discuss how we are extending our studies to gain insights into how plants regulate starch turnover, metabolism and growth in the field. I will suggest that regulation networks have evolved to cope with these variations. This carries the implication that key features of the networks may make little or no sense unless studied under conditions appropriate to the field.
