New experimental and computational techniques provide innovative opportunities to study the evolutionary history of genomes (the genetic material of a living being) and to reconstruct the emergence of new traits and characteristics of species, for example insects. Those responsible for "GEvol" are using these new techniques and bringing together researchers from the fields of genomics, bioinformatics, evolutionary ecology, molecular evolution, developmental biology, taxonomy and genetics to exploit the dynamics and principles of genomic innovations of a large clade. "In the project, we are investigating, among other things, the processes underlying the most important genomic innovations in evolution - for example, gain and loss of sociality or mating systems, defence and immunity, developmental and morphological innovations and plasticity," says Erich Bornberg-Bauer.
20 to 25 groups work collaboratively under the umbrella structure of GEvol. The SPP promotes the use of new and innovative computational and experimental techniques across groups throughout the German research landscape, training a new generation of young researchers in the field of genomics. Around 20 young researchers receive state-of-the-art technical and scientific training in a highly interdisciplinary setting.
In addition to coordinator Erich Bornberg-Bauer, there are four other members on the SPP committee. They come from the Institute of Zoology and Anthropology (Göttingen University), the Senckenberg Biodiversity and Climate Research Centre (Frankfurt am Main), the Zoological Research Museum Alexander Koenig (Bonn).

The worldwide day of action on 25 November recalls the high level of violence against women. The Federal Minister for Women's Affairs, Dr. Franziska Giffey, is calling for the help line to be made public on this day to show those affected a way out of violence.
The University of Münster is again participating in this campaign this year. In a large photo campaign, numerous departments and central units have clearly positioned themselves against violence against women.

Many flowering plants produce highly diverse and specific floral scents that are important for mediating interactions with their pollinators and/or herbivores. The well-known fitness effects and extraordinary diversity of floral scents provide an excellent system for studying the evolution of novel adaptive traits in plants. However, very few studies have revealed how plants evolve new floral scents.
In this study, a group of scientists from Max Planck Institute for Chemical Ecology and University of Münster uncovered the biosynthetic machinery and evolution of a species-specific nocturnal floral volatile of a wild tobacco (Nicotiana attenuata): benzyl acetone (BA), a compound that mediates both pollinator attraction and florivore deterrence. They demonstrated that three genes, NaPAL4, NaIFR3, and NaCHAL3 are sufficient and necessary for the BA biosynthesis in N. attenuata. They also found that while independent changes in transcription in all three genes contributed to intraspecific variations of floral BA emission, the gain of expression of NaIFR3 resulted in the biosynthesis of BA, which was only found in N. attenuata. Because NaIFR3 evolved from a gene duplication that occurred earlier than the diversification of Nicotiana, this study provided an example that novel metabolic pathways can arise via altering the expression of existing genes.
The study not only revealed how novel adaptive traits have been evolved, but also shows different genetic mechanisms are involved in intra- and interspecific variations of adaptive traits. Scientists found that while all three biosynthetic genes contributed to the intraspecific variations of floral BA emission, only the expression changes in NaIFR3 contributed to differences in floral BA emission among closely related species. The results indicate that adaptive traits might evolve differently between and within species.
The study showed that a new metabolic pathway can arise via expression changes in a single gene. Such mechanism might not only explain the evolution of amazing diversity of specialized metabolites in plants, but also demonstrated the potential of using metabolic engineering in crop development and protection.

The University Society Münster has honored the outstanding research achievements of two young scientists of the Westfälische Wilhelms-Universität Münster (WWU): In a ceremony the physician Prof. Dr. Maged Alnawaiseh and biologist Dr. Susann Wicke received this years award for the promotion of young scientists. The awards are endowed with 5,000 euros each provided by the University of Münster.
How do animals think and feel? Are there pessimists and optimists among them? How does the environment affect their well-being? Animal researchers investigate all this at the Westfälische Wilhelms-Universität Münster (WWU). If you want to learn more about these and other exciting topics, you do not have to go on nature trips or to the lab. With the new program "e-vite a prof!" ("Invite a Professor") scientists of our department will now come to all interested parties and talk about their research results - in schools, clubs or in other groups.
