Final Report Abstract

Plants and algae sustain life on Earth by converting light energy, water, and CO2 into chemical energy. Crop plants in particular provide the foundation for human civilizations. However, arable land is becoming scarce and resources, such as water and fertilizers, are becoming depleted. The consequences of anthropogenic climate change and of a continuously growing human population constitute major challenges for sustainable food security. These challenges demand innovative strategies for sustainable plant production that are based on a fundamental understanding of how plant species adapt to their environmental and cope with environmental constraints. The answers to these questions are encoded in natural and artificially-induced genetic variation that enables plant species and their associated microbes to colonize almost all terrestrial environments. The aim of the Excellence Cluster on Plant Science CEPLAS was to decode this information for four specific complex traits that are crucial to resource-efficient plant growth: (A) annual and perennial life histories, (B) C4 photosynthesis, and (C) molecular and (D) metabolic mechanisms of plant-microflora interactions. CEPLAS I combined the scientific capabilities available within the Cologne-Düsseldorf region to create a unique interdisciplinary team of experimental and theoretical biologists. Jointly, the team decoded the genetic architecture underpinning complex plant traits that have evolved independently or were lost repeatedly during flowering plant evolution, such as perennial and annual life histories or different modes of photosynthetic carbon assimilation. Using combinations of quantitative genetics and genomics, computational modelling and plant biochemistry, as well as most recent technologies, CEPLAS researchers have unraveled the genetic mechanisms underpinning life history transitions, the evolutionary trajectory from C3 to C4 photosynthesis, and the complex composition of the plant-associated microbiome. CEPLAS researchers have developed important community resources, such as a microbial culture collection that represents the majority of plant-associated bacteria. Human capacity building included the recruitment of 11 new faculty in the field of plant and microbial science as well as in computational, synthetic, and theoretical biology. Notably, two faculty have been recruited via prestigious Alexander von Humboldt-professorships. A particular success was the introduction of the tenure-track system for the recruitment of earlycareer faculty into independent positions with defined career perspectives. Further, CEPLAS established innovative programs for the promotion of early career researchers, including a 4-year Bachelor Program in Quantitative Biology, a Graduate School, and a structured Postdoctoral Training Program. Moreover, CEPLAS actively engaged in public and political outreach through novel formats of science communication and dialogue with society and relevant stakeholders.
