The Collaborative Research Centre (CRC) 973 “Priming and Memory of Organismic Responses to Stress“ is a research platform that has been initiated by the Freie Universität Berlin (FUB) (speaker university). Participating institutions are the University Potsdam (UP) and the Max-Planck-Institute of Molecular Plant Physiology (MPI-MP) in Potsdam-Golm. The CRC is funded by the German Research Foundation (DFG) for a second period of 4 years (July 2016 to June 2020). The CRC comprises 17 research projects led by principal investigators of the FUB, UP and MPI-MP. An Integrated Research Training Group for the scientific qualification of PhD students is part of our CRC. In addition, we started to establish a common database (INF project) which will support proper data documentation and facilitate data comparisons when searching for common patterns or stressor-specific mechanisms of priming. The major structural aim of the CRC 973 is to link ecological science with molecular biology and biochemistry. The scientific aims are outlined in the column “research”. Speaker of the CRC is Prof. Dr. Monika Hilker and Vice Speaker is Prof. Dr. Tina Romeis (both FU Berlin).
