Plant Innovations that Changed our Planet

Ralf Reski is invited speaker at the Summer Symposium of the Julius von Sachs Institute at the University of Würzburg, Germany, on 27th July 2017 to present his research in the talk "Cuticle, sporophyte, stomata: three plant innovations that changed our planet". He introduces research that he and his team published in the renowned journals Nature Plants and Nature Communications about the innovation of a protective outer layer, pores in the epidermis as well as the molecular mechanism responsible for the alternation of generations between sexual and asexual reproduction. All three innovations of mosses once were a prerequisite to conquer new ecosystems formerly unavailable for plants.

The Protective Layer of Prehistoric Land Plants

An international research team has discovered a mechanism in mosses that was crucial for the evolution of ecosystems on land. They discovered a biochemical pathway that is responsible for the development of cuticles in the moss Physcomitrella patens. These waxy coverings of epidermal cells are the outer layer of plants and protect them from water loss. In the Journal Nature Communications the biologists describe that the enzyme CYP98 from the family of cytochromes P450 is responsible for the development of a phenol-enriched cuticle in Physcomitrella whereas it is known to initiate the production of lignin in seed plants. Plant cuticles came into being more than 450 million years ago when the first plants colonized the hitherto hostile landmasses. Because the waxy cuticles protect against water loss, they enabled the spread of plants on land and the subsequent evolution of our complex ecosystems. The research team was led by Professor Ralf Reski from the University of Freiburg/Germany and Doctor Danièle Werck-Reichhart from the Centre National de la Recherche Scientifique (CNRS) Institute of Plant Molecular Biology (IBMP) in Strasbourg/France. The results also suggest new biotechnology strategies for engineering biopolymers in plants beyond the well-known lignin production of trees.

Survival Artists in the Antarctic

Improve our understanding of the impact climate change on plant life in the Antarctic is a new research project in the ReskiLab. Biologists Prof. Dr. Ralf Reski from the University of Freiburg, Germany, and Dr. Hyoungseok Lee from the Korea Polar Research Institute KOPRI, South Korea, will join forces to decipher the genome of an Antarctic strain of the moss Sanionia uncinata. In a second step the genome will be compared to the genome of the model moss Physcomitrella patens, which cannot grow in Antarctica. The project will be funded by KOPRI’s “Polar Genomes 101 Project”. “We are excited about this new opportunity and expect new insights into plant adaptation to harsh environmental conditions,” says Reski. Therefore the Rector of the University of Freiburg/Germany, Prof. Dr. Hans-Jochen Schiewer, and the President of the Korea Polar Research Institute KOPRI, Dr. Ho-Il Yoon, have just signed a co-operation agreement on moss research.

Biologists Discover Origin of Stomata

An international team has discovered a genetic mechanism that is responsible for the development of stomata – microscopic valves on the surface of plants that facilitate the uptake of carbon dioxide and the release of oxygen and water vapor. The researchers discovered this mechanism, which was previously known in flowering plants like Arabidopsis thaliana, in the moss Physcomitrella patens and found similarities between the two, implying that it already existed in the last common ancestor of mosses and flowering plants. The team was led by the biologists Professor Ralf Reski from the University of Freiburg/Germany and Professor David J. Beerling from the University of Sheffield/UK. The results were published in the journal Nature Plants.

How to get rid of proteins

Scientists of the Reski lab discover substrates for targeted protein degradation. A German team led by the Freiburg-based biologist Professor Ralf Reski has discovered substrates and interaction partners of the so-called N-end rule pathway of protein degradation in the moss Physcomitrella patens. The study is published in the journal Molecular and Cellular Proteomics.

No sex required

A German-Israeli team led by the biologists Professor Ralf Reski from Freiburg and Professor Nir Ohad from Tel-Aviv has discovered a gene trigger in the moss Physcomitrella patens which leads to offspring without fertilization. The researchers assume that this mechanism is conserved in evolution and holds the key to answer fundamental questions in biology. The study is published in the journal Nature Plants.

Moss beats Human

A group of German, Belgian and Japanese scientists, coordinated by Professor Ralf Reski from the University of Freiburg, Germany, published a new study in the journal BMC Genomics where they describe 32,275 protein-encoding genes from the moss Physcomitrella patens. This is about 10,000 genes more than the human genome contains.

Cosmoss.org

The model organism database cosmoss.org was launched in 2003 and has been serving as the central knowledge and data base throughout the genome annotation history of Physcomitrella patens. Ever since its launch cosmoss.org has aimed for continuous integration of published data from public repositories and collaborators around the world, including important milestones such as the first draft genome, the genetic map and the complete history of genome annotations from the very first (V1.0) to the most recent version (V3.3).

As such an essential repository it provides newcomers with a single, primary interface to explore the features of this flagship plant genome. At the same time, it provides the established scientific community with an up-to-date resource for comparative analyses. Key features include an integrative genome browser, collaborative annotation tools and a wiki as the central documentation platform.

Cosmoss.org was initially funded by the German Research Foundation DFG and is hosted, maintained and constantly improved by the Chair of Plant Biotechnology at the University of Freiburg, Germany.
