Research Plan

At the long term the envisaged research and method development aims at providing both an understanding of system level adaptation processes of plants to environmental challenges and the means for a targeted improvement of crop plants.

Great value is set on the establishment of a strong research and teaching infrastructure in Systems Biology at the Potsdam-Golm Science Centre, with a particular focus on plants.
The research programme in GoFORSYS will be organised in six work packages (WP), each of which will managed by one of the Partners as indicated:

WP 1: General bioinformatics and computational methods 

WP 2: Development of new analytic tools for systems analysis

WP 3: Multilevel systems analysis of responses in Chlamydomonas

WP 4: Testing of the applicability of models developed in Chlamydomonas 
           by comparison with the response of model higher plants

WP E: Implementation of the educational concept

WP M: Management of the project

Each work package consists of a number of sub-work packages.

 

WP 1 General bioinformatics and computational methods

managed by Prof. Dr. Joachim Selbig, Institute of Biochemistry and Biology and Institute of Computer Science / Bioinformatics, University of Potsdam

Systems Biology means integrating experimental data with computational and theoretical approaches to build an understanding of pathways, cells, organs, and complete organisms. It combines concepts from different scientific disciplines to obtain an integral understanding of biological systems in terms of their components and their interactions. Systems Biology is characterized by a diversity of heterogeneous data including discrete sequence information, continuous gene expression data, functional annotations of genes, networks of interacting molecules, sets of differential equations describing the dynamics of the underlying system, localizations of proteins within a cell, phylogenetic trees relating species, and numerous other data types. Therefore, the seamless integration of such disparate data sets is an essential prerequisite for any Systems Biology approach and poses formidable challenges to the Bioinformatics infrastructure development work. Sub-work packages WP1.1 and WP1.2 focus more on traditional Bioinformatics whereas sub-work packages WP1.3 and WP1.4 focus more on Systems Biology.

WP 1.1 Data warehousing

WP 1.2 Genome analysis and comparison

WP 1.3 Integrated data analysis

WP 1.4 Modelling and simulation methods

 

WP 2. Development of new analytic tools for
         systems analysis

managed by Prof. Dr. Bernd Müller-Röber, Institute of Biochemistry and Biology / Molecular Biology, University of Potsdam

Many analytic platforms required are already established or can be rapidly adapted including commercial expression arrays for Chlamydomonas, Arabidopsis and tomato, robotized enzyme assays for >45 enzymes, rapid robotised assays for total protein, chlorophyll a, chlorophyll b, and starch, GC-TOF and LC-MS metabolite profiling, nuclear transformation of the species used and plastid transformation.
However, in some cases further development will be required, and these are listed as specific work packages.

WP 2.1 Quantification of proteins

WP 2.2 Analysis of protein turnover

WP 2.3 Elaboration of metabolite profiling

WP 2.4 Analysis of fluxes into specific products

 

WP 3. Multilevel systems analysis of responses

         in Chlamydomonas

managed by Dr. Ralph Bock, Director, Department 3,Max Planck Institute of
Molecular Plant Physiology

WP 3.1 Different steady state conditions

WP 3.2 Genetic manipulations

WP 3.3 Time resolution of responses in transients

 

WP 4. Testing of the applicability of models developed
         in Chlamydomonas by comparison with the

         response of model higher plants

managed by Prof. Dr. Mark Stitt, Director, Department 2, at the Max Planck Institute
of Molecular Plant Physiology

In general, two different sorts of experimental systems will be used to test the applicability of the models developed in Chlamydomonas to higher plants. The first (WP4.1 and 4.2) will involve analysis of the response in higher plants to the same environmental challenges that are analysed in Chlamydomonas (light intensity, light quality, temperature, nitrogen). The second (WP4.3 and 4.4) will be based on natural variation in the rate of photosynthesis and growth found in a model plant species (Arabidopsis) and a model crop (tomato). Natural diversity is used because this is an unbiased source of variation, which has been selected for, and in which it can be asked if changes in the composition of the photosynthetic apparatus lead to a predictable phenotype, i.e. predicable changes in the rate of photosynthesis and the response to different environmental conditions.

WP 4.1 Responses to environmental changes

WP 4.2 Similarity of the regulatory networks

WP 4.3 Identification of genotypes differing in photosynthesis and growth

WP 4.4 Systems analysis to identify the molecular basis of genotype-
            related differences in photosynthesis and growth

 

WP M: Management of the project

This WP comprises all activities related to the management of the IRC.

WP M.1 Coordination of activities

WP M.2 Communication

WP M.3 Development of new initiatives

 

WP E: Implementation of the educational concept

for the implementation of a high-quality international PhD Programme on Systems
Biology.
