Summary

A8 (Kaufmann, Wigge, Ohler) investigates the molecular basis of cell-type specific plastic responses to temperature and nitrogen supply, including cellular differentiation trajectories. In particular, the aim will be to construct a comparative cellular atlas of environmental plasticity in leaves as important environmental sensory organs. The project will map cell-type specific regulatory responses at a genome-wide scale in a comparative manner in A. thaliana and C. bursa-pastoris using tissue-level and single-cell transcriptomics and chromatin accessibility studies. The resulting atlas will facilitate analyses in all other projects of the CRC.
