Gatersleben Lecture - The dynamics of root development

To understand the dynamics of root cell specification, root growth and root passage through soil we have developed new experimental, analytical and monitoring methods. To identify networks functioning within different cell types and developmental stages of the root we generated an atlas based on single cell RNA sequencing of over 100,000 cells. We are particularly interested in a subnetwork that regulates a key asymmetric cell division of a stem cell and the regulatory networks that control differentiation of the stem cell’s progeny. To quantify dynamic aspects of these networks, we used high resolution time-lapse imaging of living roots to quantify accumulation of the different network components. How roots explore their soil environment determines their ability to acquire nutrients and water. We identified the molecular mechanism underlying the circular movement of the root tip known as circumnutation. In work with Hi Fidelity Technologies we have developed a technology platform able to monitor root growth in soil in controlled environments and under field conditions.
