Objective
Global change is expected to amplify the frequency and the severity of heatwaves and drought events especially in Western Europe. These droughts jeopardize tree health and integrity of European temperate forests and tied ecosystems. There is a need to identify the processes that may allow trees to overcome severe water scarcities. Tolerance to xylem embolism is an intrinsic and operational trait related to tree drought resistance. Moreover, ecophysiological studies have pointed to the existence of hydraulic capacitance connected to embolism as a preventive way out against moderate desiccation avoidances and buffering water potential fluctuations. This capacitance influence is expected to be ensured by living xylem elements (capacitors). However, capacitance is paradoxically a rare physiological event underlined, as the physical and genetic basis of capacitance remain totally unresolved.
Here the aim of the project is to define the “hydraulic capacity” of xylem capacitor elements under quantified changes in xylem water tension state, and to identify a class of genes placed alongside physiological and biochemical measurements that will highlight the functioning of these capacitors. To achieve this task, our strategy will be first to identify the key ecophysiological features of xylem capacitance and secondly, we will undertake a molecular study to correlate the potential involvement of genes (WAK and MIP) coding for this process. Lastly, we will perform the functional validation of related proteins of interest by biochemical and bioinformatic approaches.
This tree hydraulic capacitance project fits perfectly into the framework of Marie Curie Actions, spanning the “Environmental and Geo-Sciences” and “Life Sciences” themes. As the underlying nature involving drought adaptive responses using cell water capacitance may be common to all living organisms, this project can expect to contribute to this growing pool of knowledge and skilled researchers in the ERA.
