SPP 2125:  Deconstruction and Reconstruction of the Plant Microbiota "DECRyPT"

The central scientific objectives of this priority programme (SPP) are to obtain deep and potentially predictive insights into plant-microbiota associations and to develop pioneering reductionist approaches towards a molecular understanding of plant microbiota functions. This SPP will elucidate genetic factors underlying plant microbiota establishment, test presumed community adaptation in ecological contexts and define community-associated emergent properties. Computational and genomic tools will guide hypothesis-testing and the design of microbiota reconstitution experiments in controlled environments.
