Playing hard to get: The troublesome acquisition of soil-immobile nutrients

Research in my lab focuses on the elucidation of acquisition strategies for the generally soil-immobile mineral nutrients iron, phosphate and manganese. In particular, we seek to understand how plants control the uptake and distribution of these nutrients in response to changes in their availability. Such recalibration of cellular ion concentrations involves perception and communication of the nutrient status, re-programming of metabolic and developmental pathways, alterations in chromatin organization and a rearrangement of the translational machinery.

Plasticity on the move: Cell fate assignment dictated by migrating R3 MYB proteins

The fate of root epidermal cells, which differentiate into either root hair or non-hair cells, is determined by a complex interplay of edaphic genetic and systemic signals that results in a predictable but highly plastic pattern of epidermal cells that can vary in shape, size and function. Understanding the mechanisms that drive this plastic development of plants is of utmost importance against the background of a changing climate and the negative environmental aspects of intensive agriculture. In particular, we are investigating the role of the non-cell autonomous R3 MYB proteins CAPRICE and its paralogs in cell fate decisions in response to environmental cues.
