Developmental Physiology

Plant roots acquire water and nutrients from the soil and transport them upwards to the aerial parts. This function is reflected by their anatomy: Water and nutrients move radially through the concentric layers of epidermis and cortex before entering the vasculature through the endodermis. Our research aims to study the relations between root development and nutrient uptake by combining microscopy, molecular genetics and plant physiology. Current projects in the lab include characterization of apoplastic, symplastic and transcellular pathways for nutrients.
