The specialist group was founded under the name "Regulation and Signal Transduction in Prokaryotes" in September 2005 and has grown to 333 members since its foundation. In order to take account of increasing internationalisation, the name of the specialist group is currently being changed to "Regulation". This title works in both German and English. By removing the restrictions "Signalling in Prokaryotes", the division is also opening up to eukaryotic microorganisms. In addition, the new name reflects the wide range of possibilities available to microorganisms to interact with their environment and control intracellular processes:

The enormous adaptive capacity of prokaryotes is based on a complex and powerful regulatory network consisting of many individual reactions that are interconnected and feedback-connected in parallel or in series. This regulatory network forms the basis for processes such as the prokaryotic cell cycle, cell differentiation, the expression of virulence, multicellular coexistence, adaptation to the respective environmental conditions and population dynamics. We are still in the early stages of understanding the regulatory network of a prokaryotic cell in time and space.


Minisymposia at the VAAM Annual Conference

The specialist group takes this exciting problem into account by organising an annual symposium on a highly topical subject; this is embedded in the framework of the annual VAAM conference. Suggestions for potential topics in the coming years are always welcome from the members of the specialist group and should be addressed to the speakers of the specialist group. After the Division's mini-symposia could only take place online in recent years due to the pandemic, a face-to-face event on "Post-translational regulation in microorganisms" is planned again for the 2023 annual meeting in Göttingen.


Two digital lunch meetings were successfully held in 2021 and 2022 to facilitate dialogue between the specialist group members during the pandemic. In addition, two specialist group prizes for young scientists were awarded for the first time in 2022.


As a continuation of the "Plasmid Symposium", which has been held since 1977, the specialist group also organises a conference every two years at which preferred young scientists present their work. The 32nd "Mechanisms of Gene Regulation" event in Tutzing in September 2018 was organised by Ralf Heermann (JGU Mainz) and Kai Papenfort (LMU Munich). Due to the pandemic, the next event had to be postponed and was finally held as a virtual autumn school on regulation and signal transduction in prokaryotes (RSTiP21) on 15-16 November 2021. Another face-to-face event is planned for late summer 2024. Following on from the success of the 2021 online event, this will alternate with a binational virtual summer school, which will then take place from 2025.
