Anna Amtmann - Unravelling cell-type specific regulatory networks in plant roots

The cell layers surrounding the mature root xylem have essential functions in controlling long-distance transport and are targeted by radial signals reporting on nutrient and water availability in the soil. Cell-type specific gene expression is important for both function and regulation. Combining FACS/RNA-Seq with INTACT/ChIP we identified a core set of cell-type specific H3K27me3-de-repressed genes that provide us with a basis to re-construct cell-type specific transcriptional networks from the bottom up.
