Research Interests

Symplastic communication in root development

In plants, cell-to-cell channels (called Plasmodesmata; PD) connect the cytoplasm of neighboring cells, forming the symplasm. These cytoplasmic bridges underpin the molecular communication required for coordinated development and growth, and for responses to the environment. PD are also the gateways for the vascular network that allows systemic transport of nutrient and metabolites around the plant.

Research in our lab aims to establish the importance of plasmodesmata transport in post-embryonic development and to reveal regulatory mechanisms controlling this form of intercellular communication.

Specifically, we study how symplastic communication influences root development in the model plants Arabidopsis thaliana and Medicago truncatula. Root post-embryonic development is characterized by the maintenance of the apical meristem and the continuous formation of new organs (such as lateral roots and nodules). Without a proper root system, plant uptake, fixation and transport of water, minerals and nutrients from the soil will be compromised. Therefore research aiming to optimize root architecture will directly impact on plant development, performance, productivity and adaptation to adverse environments. This is the ultimate goal of our research projects.
