Summer School: Why numbers matter

The contributors and participants of the Summer School came together from five university places: Photo and (c): Andreas Richter

The Summer School „The Numbers Matter: Exploring Photoautotrophic Organisms through Quantitative Biology” took place from 15th to 19th September 2025 at the Institute for Biosciences at the University of Rostock. Fourteen PhD students and Rostock’s colleagues discussed recent findings, experienced hands‐on workshops on quantitative techniques. Theoretical lectures accompanied the lab courses. The organisers Jun.-Prof. Dr. Jennifer Selinski (Kiel) and Jun.-Prof. Dr. Andreas Richter (Rostock) report on the topics and contributions of the DBG-supported Summer School.

The new generation of plant scientists from Munich, Kaiserslautern, Münster, Kiel, and Rostock, who participated in the summer school, benefited from lab courses and hands-on experience in analyzing photosynthesis, photosynthetic complexes, carbohydrates, targeted gene expression, and the analysis of antioxidative enzymes. During the courses, the students were trained in new techniques, including non-toxic RNA extraction, quantitative gene expression analysis, gas chromatography, photosynthetic gas exchange, and automated protein complex purification, which were previously unfamiliar to them. Through intensive discussion of the protocols and procedures, the participants deepened their understanding of the quantitative extraction and analysis of plant-derived biomolecules essential to cellular functions. 

The practical work was accompanied by lectures on the mission of the NFDI initiative ‘dataPLANT’ FAIR digital objects and research data management, presented by Prof. Dr. Timo Mühlhaus (RPT University Kaiserslautern-Landau). Prof. Dr. Iris Finkemeier (University Münster) introduced the students to the field of plant proteomics, the theoretical principles and the application of quantitative mass spectrometric analysis for plant research. 

The organizers are grateful to all supporters and the lively contributions of all participants, which will undoubtedly transform the gained experience in cellular plant biology into a valuable contribution to the field of science, providing solutions to modern life's most pressing societal questions and challenges, particularly those related to plant biology and crop performance.
