Samuel Zeeman

Prof. Dr.

Samuel C Zeeman is a full professor of Plant Biochemistry at ETH Zurich and head of the Institute of Molecular Plant Biology. His research group studies the pathways and products of plant primary metabolism using a combination of plant molecular genetics, biochemistry and physiological approaches. Sam is particularly recognized for his contribution to the understanding of starch metabolism using the model plant Arabidopsis thaliana. Starch is a fascinating semi-crystalline substance uniquely produced by plants and algae. Work on Arabidopsis has facilitated the discovery of numerous previously unknown proteins that help to control starch synthesis and starch degradation. This field is very important to society since starch is the major nutritional carbohydrate in our diet. As starch metabolism is widely conserved in plants, the results of fundamental research on model systems is highly applicable for the improvement of staple starch crops, including the storage roots of cassava by altering yield and quality.

Dr.

Laure David is a postdoc in the Plant Biochemistry group of Sam Zeeman at ETH Zurich. Her research focuses on regulation of starch metabolism. For the CASS project, she also analyses starch and cell wall properties among different accessions of cassava to study how these traits affect end-product quality. In collaboration with IITA researchers, Laure successfully conducted the first confined field trial of the project in Nigeria. Here, cassava lines with reduced starch remobilization upon pruning were investigated. Laure successfully demonstrated that the plants indeed displayed lower starch remobilization upon sink to source transition and thus exhibited higher starch content at harvest time.

Dr.

Simon Bull is a Senior Assistant in the Plant Biochemistry group (Prof. S. Zeeman) at ETH Zurich, Switzerland. He is also affiliated with the Molecular Plant Breeding group (Prof. B. Studer) at ETH Zurich.  His research interests include developing and implementing new plant breeding techniques (e.g. genome editing, fast flowering) in apple and cassava for fundamental research and trait improvement. Within the CASS project, he is investigating starch granule formation to boost our understanding of starch biosynthesis in cassava, and to apply this knowledge to improve starch-quality traits.
