Anabaena sp. PCC7120, a model for cell differentiation and chloroplast evolution
Cyanobacteria are a group of prokaryotic organisms characterized by their ability to fix CO2 by oxygenic photosynthesis. They are considered the ancestors of the chloroplasts and the inventors of oxygenic photosynthesis, and are among the most important primary producers of the planet. They represent a phylogenetically coherent group, but show a very diverse morphology and have colonized a wide diversity of habitats. read more
In contrast to bacteria, a higher complexity of eukaryotic cells comprises tissue specific expression of genes, occurrence of post-transcriptional changes and alternative splice forms. Analyzing tissue and stress dependent expression on transcriptomic and proteomic level could give insights in core sets of plant specific expression patterns. Furthermore, comparing the expression pattern and function as well as the gene composition in different plant species can clarify the evolution of plants. Besides analysis of structural and domain architecture on RNA and protein level to detect possible motifs which are required for targeting or stress related answers are of interest. read more
The function of cytosolic, high molecular weight chaperones in protein sorting and regulation of protein homeostasis
Molecular chaperones form a network of proteins involved in the control of the cellular protein homeostasis under normal and stressful growth conditions. In plants they are encoded by several multigene families of an unusually high complexity. This can only partially be explained by specific developmental and stress-induced expression patterns of individual members in each family and/or by differences in the subcellular distribution of the corresponding proteins. read more

Ribosome Biogenesis in Plants
Ribosome biogenesis is one of the major biosynthetic pathways, which, for eukaryotes, is best understood in Saccharomyces cerevisiae. Yeast ribosomes consist of 79 ribosomal proteins and four ribosomal RNAs (rRNAs). The assembly of the ribosomal subunits is a highly complex process that involves more than 200 cofactors. An exponential grown yeast culture builds around 2000 ribosomes per minute per cell, uses 60 % of its energy for this process and ca. 10% of the genome capacity is taken by ribosome biogenesis. This clearly underlines the importance of ribosome biogenesis for a living cell. read more
