Cell communication: Long and short distance transport

Our work is focussing on the biology of communication in higher plants which coordinates growth and development and allows adjustments to biotic and abiotic stress. There are two alternative pathways for cell communication across the cell wall:

  • Indirect contact across the plasma membrane, where it is controlled by channels, transporters and receptors on either side, or
  • Direct contact via plasmodesmata, where it is controlled by plasmodesmal proteins and the endoplasmic reticulum. 
  • For long-distance communication, the plant utilises a special tissue (phloem).

We pursue our research using advanced and cutting edge microscopy, such as present in the Center for Advanced Bioimaging (CAB), and physiological and biochemical approaches, including nanosensors.

We are moreover involved in uncovering dynamic molecular interactions such as protein-protein interactions in the DNRF center DynaMo.
