The research questions being addressed by BARN will be distributed over 6 work packages. Each work package has a WP-Coordinator.
The six work packages were defined in such a way that a significant area of root biology will be covered while a maximal level of focus will be maintained. The research themes representing the centres of interest are: - root growth and architecture as the result of the interplay between cell division and cell elongation,
- the hormonal signalling involved in root growth,
- root-shoot signalling in floral transition,
- the effect of abiotic stress conditions on root development
- nutrient and water transport in roots in relation to respectively H-ATPase and aquaporin plasma membrane transporters.
The acquired biological data will be implemented in a multi-scale modelling framework that will be created in a separate work package. Such a modelling framework will be instrumental to assist in finding answers to the major biological questions of the network.
In addition, it is the intention to realise an important exchange of up-to-date specialised techniques that are available in several of the contributing laboratories by defining integrated advanced technical platforms. These platforms will be available for all partners of the network and will be essential tools to answer the biological questions of this network.
