Plants are at the core of nature´s garden - just imagine what would we be without them? Perhaps most importantly, plants are capable of harvesting sunlight in a process termed "photosynthesis" that takes place inside green cells in so-called chloroplasts. Unfortunately this clever process, which basically takes advantage of the light energy for synthesis of molecules that are good for the plant and for us, has one serious drawback: The photosynthetic apparatus gets rapidly destroyed unless its core proteins are replenished as a result of gene expression. Exactly how this happens is still far from clear, but research on the underlying gene regulatory mechanisms can be considered to provide major advances in our understanding, and may guide attempts to control these processes. Considering the importance of plant products for human well-being, the potential of research in this area can be readily envisaged.
We have concentrated our efforts on chloroplast proteins involved in the control of gene expression, e.g. RNA polymerases, transcription factors, DNA- and RNA binding proteins, and signaling components including protein kinases and redox mediators. We have isolated and characterized a number of these proteins and have succeeded in the cloning of their genes. This has allowed insights into the role and interaction of various components of the plastid gene expression system, as well as in their coding site and intracellular site of synthesis. Gene cloning and overexpression, in combination with mutational and functional assays, have helped reach a better understanding of plastid gene expression in general, and this may provide a basis for strategies to optimize plastid biosynthetic processes in a specific developmental and environmental context.
