For almost 30 years, water flow into and out of a cell has been known to be regulated by channel proteins called aquaporins. Because the H2O molecule is forced to cross membranes at certain points on its way from the roots to the leaves, aquaporins are believed to be the main regulators of water flow. Furthermore, even though quite simple in structure, aquaporins come in a variety of different isoforms, each specific to certain membranes. While a lot of research has focused on their structure and function, unfortunately not much is presently known about how these channel proteins control water movements within an entire plant.

          To make matters more complex, the different isoforms are expressed in different tissues, have varying substrate permeabilities, and may interact with each other within the membrane. Thus, our understanding of the concept of whole plant water balance is still quite incomplete. My goal is to find out how water molecules are guided along their way through the plant and to eventually use this knowledge to improve plant productivity.

 

My main aims using the model plant Arabidopsis thaliana are:

  1. Characterising the role of aquaporins expressed in the plasma membrane on the level of the entire plant.
  2. Identifying the influence of aquaporin expression on photosynthesis, water use efficiency, water uptake and root system architecture.
  3. Further clarify the function of the carbon dioxide conducting PIP1;2 isoform on the level of the whole plant.
  4. Creating more efficient and/or more productive plants by manipulating aquaporin expression through genetic or environmental means.
