Selected projects

  • Intercellular communication is critical for multicellularity. In plants, the Plasmodesmata (PD) pores, interconnect virtually all cells within the plant body, establishing direct membrane and cytoplasmic continuity, a situation unique to plants. PD are decisive for development, environmental adaptation, defense signaling, and spreading of viruses, yet their mode of action remains elusive. Our focus is to understand the molecular mechanisms governing PD function, and provide a link between PD unique membrane organization and the regulation of cell-to-cell signalling by addressing the following questions:

    1 What are the molecular determinants of PD function?

    2 What role lipids play in organizing PD specialized membrane domains?

    3 How does PD 3D architecture relate to their function?
