Actualia (2026) - Notifications of the Society

The 14^th edition of the Plant Peptide Receptor Meeting brought together around 90 participants and eight international speakers. The meeting took place from September 14^th to 16^th in the Marriott Hotel in Freising (Germany). This edition was co-organised by Julien Gronnier (TUM), Kate Parys (LMU) and Isabel Monte (University of Tübingen). Usually attended by European researchers working on plant peptides and receptors, the PPRM 2026 comprised invited and selected speakers from Europe, China, Taiwan, USA and Australia. With 27 short talks and 20 flash talks selected from abstracts, early career researchers (ECR) had ample opportunities to showcase and discuss their research. 

To celebrate the awarding of this year’s Nobel Prizes to two members of our German Society for Plant Sciences (DBG), DBG doubles the prize money for the master’s theses to 200 Euros each. In this way, our society aims to give special recognition to the best theses by early career researchers (ECRs). The alga scientists Professor Peter Hegemann (HU Berlin) and Professor Georg Nagel (University of Würzburg) paved the way for a new research discipline with their basic research on the so-called channelrhodopsins (see: Nobel Prize for two members and discoverers of channelrhodopsins). Together with this year’s third Nobel laureate, Professor Karl Deisseroth (Stanford University), they developed their research further into optogenetics, since they had already recognized potential applications of rhodopsins at the beginning of the century. Now the light-controlled rhodopsins can be “integrated” into the nerve cell membranes to selectively activate and deactivate nerve and brain cells from the outside, much like a light switch. Plant research also uses this technique for contactless control of electrical stimuli, which can be applied with pinpoint precision and at variable frequencies and amplitudes (see also: So profitiert die Pflanzenforschung von der mit dem Nobelpreis ausgezeichneten Optogenetik). Therefore, established plant scientists have one more reason this year to nominate promising candidates to the contact persons at the participating universities to recognize the achievements of early career plant scientists.

Nearly 100 researchers from 20 countries gathered in Gatersleben for Nitrogen 2026, combining an international scientific programme with visits to IPK’s (Leibniz Institute of Plant Genetics and Crop Plant Research) research infrastructure, poster sessions, excursions and informal opportunities for exchange. The symposium offered an engaging setting for established researchers and the next generation of plant scientists to connect around one of the central challenges of sustainable crop production: how plants can acquire and use nitrogen more efficiently. Organiser Prof. Nicolaus von Wirén reports about the symposium in which especially the participation of early career scientists was supported by our DBG.

The 13^th International PhD School on Plant Development gathered 45 Early Career Researchers (ECR) and 13 senior scientists. It took place 23-25 September 2026 at Kloster Neustadt in Neustadt an der Weinstrasse, Germany. Organized by Moritz Nowack (VIB Ghent), Michael Raissig (University of Bern), and Arp Schnittger (University of Hamburg), the meeting relaunched this long-standing event at a new venue after the disruption of COVID-19 and the closure of its former site in Retzbach. For some of the organisers, reviving the school carried special meaning: Michael Raissig attended its very first edition as a first-year PhD student in 2008.

DBG’s Eduard Strasburger Workshop “Complexome Profiling in Plants: Exploring Organellar Protein Networks” took place in September 2026 at Leibniz University Hannover. It provided nine early-career researchers from universities across Germany with intensive, hands-on training in comparative complexome profiling, spanning sample preparation and high-resolution native protein separation in the lab to the bioinformatic analysis and evaluation of huge datasets of organellar protein networks. It allowed participants to execute each step themselves and also left ample time to address detailed individual questions that the participants returned to their institutions with concrete solutions and ideas. Details are reported by the organisers, Dr Nils Rugen and Matthias Döring. 

The new statutes of our DBG, which were sent to our members in May, were unanimously adopted during the General Assembly held on 7^th September 2026 at Ruhr University Bochum. In these the Executive Board is expanded to include two new vice-presidential posts in the long term. As a result the first new vice-president had to be elected this time. Following the discharge of the incumbent Executive Board, the members elected Prof. Dr Andreas Meyer (University of Bonn) to the new vice-president position. At the same time, they elected Prof. Dr Dirk Becker (Julius Maximilian University of Würzburg) as their new treasurer, since after ten years in this office, Prof. Dr Raimund Tenhaken had decided not to stand for re-election. The present members of the Executive Board, Prof. Dr Andreas Weber, Prof. Dr Iris Finkemeier and Prof. Dr Boas Pucker, were re-elected as DBG’s President, Secretary General and Secretary, respectively. Prof. Dr Jan de Vries (Georg-August University of Göttingen) as incoming conference chair was newly elected as a member of the extended Board, replacing Prof. Dr Christopher Grefen. Dr Sophie de Vries (Georg-August University of Göttingen), the representative for early-career researchers, was also confirmed in her office. Some of the Section‘s spokespersons were newly elected during their section’s meetings (see the section pages for more details), and, in accordance with our statutes, their first spokespersons are ex officio members of the extended Board and were therefore not standing for (re-)election at our General Assembly.

During our assembly on 7^th September in Bochum, the DBG’s members present in the room unanimously voted to elect Karl-Josef Dietz (Bielefeld University) to become new honorary member. Nominated by our current Board, DBG President Professor Dr Andreas Weber highlighted Dietz’s many scientific achievements during the Botanik-Tagung, the International Conference of our German Society for Plant Sciences in Bochum: Dietz and his research team have significantly shaped our current understanding of redox regulation, photosynthesis, and the adaptation of plants to changing environmental conditions. To this end, Dietz has published more than 300 articles and received awards for his findings. Furthermore, the Bielefeld-based plant physiologist has actively served the scientific community for many years through his work in both national and international organizations, in the German Research Foundation (DFG) and as editor of scientific journals. Our society very much thanks Karl-Josef Dietz for his many years as spokesperson for our Section Plant Physiology and Molecular Biology (2003-2009) and, above all, for the eight years (2012-2019) during which he shaped and further developed our DBG as its president, as described in the laudatory speech delivered in Bochum.

Our former Secretary General, Prof. Dr Caroline Müller, and our long-term treasurer, Prof. Dr Raimund Tenhaken, were honoured by the president, Prof. Dr Andreas Weber: With the Simon Schwendener Medal the latter sincerely thanked them in the names of all member for their continuing support of our German Society for Plant Sciences (DBG) on the occasion of the member assembly at Ruhr-University Bochum, Germany, on 7^th September. Caroline Müller (Bielefeld University) held the office of the Secretary General in the years 2018 to 2024 with exceptional commitment and her impressive efficiency. Since now ten years Prof. Dr Raimund Tenhaken (Salzburg University) is our treasurer and managed our finances conscientiously. The audience thanked both of them with a prolonged round of applause. Raimund Tenhaken also received applause and thanks from our organisation and the audience for the many years he also served on the board of DBG’s own Wilhelm Pfeffer Foundation, as its president, Prof. Dr Severin Sasso, pointed out in the general assembly.

From the more than 300 displayed scientific posters presented at Botanik-Tagung 2026, the International Conference of our German Society for Plant Sciences (DBG), the participants elected the ten best posters. The early career plant scientists (ECRs) were rewarded for their scientific work presented on the respective posters and received an endowment of 145 Euros reach, taking into account the foundation of our Society in the year 1882. The names of the awarded ECRs and the titles of the scientific posters they presented are summarized in a list. 

Biophysicist, phycologist, and DBG-member Professor Peter Hegemann (Humboldt University Berlin), the plant physiologist and member of our Section Phycology, Professor Georg Nagel (Würzburg University), together with Karl Deisseroth, Professor of Bioengineering and Psychiatry at Stanford University, jointly receive the 2026 Nobel Prize in Physiology or Medicine, as the Karolinska Institute in Stockholm announced yesterday. Hegemann and Nagel discovered the so-called channelrhodopsins, light-sensitive proteins, when they wanted to explain how the single-cell green alga Chlamydomonas senses light to move towards it. Together with Karl Deisseroth they developed the new field of optogenetics, in which these light-sensitive rhodopsins were inserted into the membranes of nerve cells. This enables to switch on and off those cells with light and to study nerve cells in living organisms and living brains. Our DBG congratulates Peter Hegemann, Georg Nagel and Karl Deisseroth to this well-deserved award. The Nobel Prizes will be presented on 10^th December to the awardees, the anniversary of the death of Alfred Nobel, who established the prizes.

In his opening speech of the Botanik-Tagung, International Conference of the German Society for Plant Sciences (DBG), our president, Professor Andreas Weber, made participants familiar with the Ruhr region and in detail with their traditional values, like hard work, solidarity, openness, and tolerance, to name a few, as well as with the people’s verbal directness common around the venue: Criticism and praise are expressed straightforwardly, candidly, and without frills. With this in mind Weber as president of one of the oldest botanical societies reminded us that scientific meetings like ours are important for the scientific community for exchanging ideas, academic networking, stirring new collaborations, and especially for launching and advancing the careers of early-career scientists (ECRs) like PhD students and postdocs. Therefore, it is crucial that those meetings are affordable, especially for researchers starting their academic careers. He put forward that meetings like our biannual conference are non-commercial, from scientists and for the scientific community, despite their organization becoming increasingly bureaucratic and expensive in recent years. Universities and scientific societies are part of the same academic ecosystem and should facilitate conferences with minimal registration fees for ECRs and scientists from less well-funded institutions to meet the challenges towards a greener and more sustainable future that gives our conference its title "From Industrial Past to Green Future".

During the International Conference of our German Society for Plant Sciences (DBG), the Botanik-Tagung, in Bochum, Germany, several early-career researchers received awards for their outstanding scientific achievements. Plant geneticist Dr Michelle Rönspies (Karlsruhe Institute for Technology, KIT) was awarded the Eduard Strasburger Prize for her paper published in Science. The PhD thesis of evolutionary biologist Dr Jaccoline Zegers (University of Göttingen) was honoured with the Wilhelm Pfeffer Prize; and the PhD thesis of macroalgae researcher Dr Sarina Niedzwiedz (University of Bremen) was awarded with DBG’s Horst Wiehe Prize. Each of the three researchers presented their findings in a plenary lecture in Bochum. Another Horst Wiehe Prize was given to plant physiologist Dr Paul Grünhofer (University of Bonn). Unfortunately, he could not attend our biannual conference since he is currently conducting research overseas. What exactly the scientific excellence of the award-winning papers and theses is, was published in a press release prior to the conference: Genome restructured, evolution of land plants, arctic kelp forests and trees’ surfaces. Also invited to our international conference were the three recipients of last year’s Best Paper Award of the DBG: Dr Sara Leite Dias (Leibniz-Institute for plant Genetics and crop research in Gatersleben, IPK), Dr Ling Chuang (during the study at Leibniz University Hannover and now at Max-Planck-Institute for chemical ecology, Jena) as well as Shenyu Liu, also at Leibniz University Hannover, for their paper published in Science on the discovery of a key enzyme with great application potential to which they had contributed in equal parts. 

Recent research developments and fundamental biological processes in energy-transducing organelles were discussed at the Gordon Research Conference (GRC) "Energy-Transducing Organelles at the Nexus of Evolutionary Biology and Synthetic Engineering" that was held from 19^th to 24^th July at the Jordan Hotel at Sunday River in Maine, USA. The conference was organized by conference chair Andreas Weber (Heinrich-Heine-University, Düsseldorf, Germany) and vice-chair Vamsi Mootha (Harvard Medical School, Boston, MA, USA). 118 researchers from five continents attended the conference, with more than 50% of the participants being early career researchers. Andreas Weber reports about the focus and recent developments across different scientific disciplines. 

What happens at the ends of proteins can determine their fate – but protein termini are increasingly emerging as much more than molecular tags for protein stability and degradation. At the FEBS (Federation of European Biochemical Societies) Workshop “Protein Termini 2026” in Italian Palermo, 152 scientists discussed how protein termini connect translation, protein maturation, proteostasis, signalling and stress responses with emerging therapeutic and biotechnological applications. Plant research is making fundamental contributions to this rapidly evolving field. Co-organiser Prof. Dr Nico Dissmeyer, reports about latest scientific developments and new perspectives. Several items on the agenda served as stepping stones for early career scientists (ECRs).

The meeting organised by PhD students for other PhD students in the fields of evolutionary biology with almost 80 participants offered all attendees the opportunity to present own research, try “alternative” presentation styles and to connect with people with similar research questions. Uliana Kolesnikova reports from the 31^st meeting that has taken place from 8^th to 12^th June 2026. 

The deadline is extended to submit your poster abstract to be presented at the International Conference of our German Society for Plant Sciences (DBG), the Botanik-Tagung (BT2026) taking place in Bochum, Germany, from 6^th to 10^th September 2026, in either one of the two possible types:

• Abstracts to be considered for a poster talk can be submitted until 11^th June, 23:59 Bochum-time (CEST).

DBG’s third Eduard Strasburger HOT TOPIC Workshop, this time on “Structural Biology – Visualization of the photosynthetic machinery via focused-ion-beam (FIB)-milling and Cryo-ET” took place from 13^th to 15^th April 2026 in the Biozentrum of the University of Basel, Switzerland. 11 PhD students and 12 PostDocs mainly from Germany but also from Switzerland experienced three intense days of teaching, experimenting and networking. The Organisers Dr Davide Tamborrini (Basel), Dr Karen Zinzius (Münster), and Fanny Le Blanc (Basel), report about microscopy techniques and challenges, data processing, three-dimensional animations, intensive discussions and in-depth dives into the topic. 

At the end of April, our honorary member, the plant physiologist Prof. Dr. Widmar Tanner (University of Regensburg), passed away at the age of 87. Thanks to his enthusiasm for experimentation, his meticulousness and thirst for knowledge, as well as his ability to connect insights across disciplines, Widmar Tanner not only established new fields of research but also shaped numerous scientists who were later appointed to professorships. In his obituary, Prof. Dr. Ekkehard Neuhaus recounts the stages of the Regensburg researcher’s career, outlines the molecular processes that Widmar Tanner uncovered and brought to international prominence, and reflects on what made him such an inspiring conversational partner.

Our honorary member, evolutionary and biodiversity scientist, Peter Hamilton Raven, has passed away on 25^th April 2026 at the age of 89 (https://www.missouribotanicalgarden.org/peter-raven). Raven, the director of the Missouri Botanical Garden in St. Louis (Missouri, USA) for four decades, shaped our understanding in ecosystem interactions and biodiversity. He was one of the first to recognize that the loss of biodiversity is not merely an academic issue, and he therefore dedicated himself to its preservation. To do so, Raven combined taxonomy, evolutionary biology and conservation and conveyed science to the public. As researcher he analysed the evening primrose family (Onagraceae), the coevolution between plants and butterflies, and wrote the well-known textbook Biology of Plants. In the years in St. Louis, he transformed the respected but provincial garden to a recognized global hub for research, education, horticultural display, and sustainability, with far-reaching scientific partnerships and conservation programs. The TIME magazine once described him as a “Hero for our Planet”. 

If you want to profit from early bird rates to come together, discuss science, meet and exchange with other plant scientists and get to know the people behind the papers, hurry up to register for the International Conference of the German Society for Plant Sciences (DBG), the Botanik-Tagung (BT2026). Around 600 scientists joined our last conference in Halle in 2024. The cheaper rates are only available until 30^th April 2026. Abstract submission deadline will be on 31^st May 2026. More details - for example about the well-known keynote and session speakers are available on the conference website. Remember to register soon, if you want to save on early bird rates.  

The 39^th Molecular Biology of Plants Conference (MBP2026) of our Section Plant Physiology and Molecular Biology brought together leading scientists, early-career researchers, and industry representatives at the Sportschule Hennef from 16^th to 19^th March 2026. Held under the patronage of the DBG Section Plant Physiology and Molecular Biology (SPPMB), the meeting once again provided an inspiring platform for scientific exchange and networking within the international plant science community. Main conference organiser Hans-Henning Kunz (LMU Munich) summarises the meeting that he and his team organised together with Christopher Grefen (Ruhr University Bochum) and Andrea Bräutigam (Bielefeld University). He not only reports about current research areas and developments in molecular plant research, but also explains which early-career researchers (ECRs) were awarded with prizes. MBP2026 showcased the latest advances in molecular plant research and reflected the diversity, innovation, and collaborative spirit of the field.

Call closes on 26^th April 2026 (12 p.m.).

Das Team  unserer Zeitschrift Plant Biology trauert tief um seinen langjährigen und hochgeschätzten Kollegen Prof. Dr. Philipp Franken. Mit großer Bestürzung haben wir erfahren, dass er im Dezember nach schwerer Krankheit im Alter von nur 65 Jahren viel zu früh von uns gegangen ist. Editor in Chief, Prof. Dr. Christiane Werner (Freiburg) skizziert seine wissenschaftlichen Stationen und was Prof. Franken auszeichnete. 

From Thursday, February 26^th to Sunday, March 1^st, 2026, members of the international maize genetics community gathered at the Maritim Hotel in Cologne, Germany, for the 68^th Annual Maize Genetics Meeting. The meeting was organized by Frank Hochholdinger (University of Bonn), who acted as chair and local host, along with the team from the maize genetics meeting steering committee. The maize meeting is one of the longest-running conferences in plant genetics and serves as a central forum for researchers working on the genetics of maize (Zea mays). The conference, which was also supported by our German Society for Plant Sciences (DBG), had taken place for the 5^th time outside the United States and for the first time in Germany. It brought together 412 scientists from 26 countries to present and discuss recent advances in maize genetics. The program featured six invited plenary talks, 30 short talks and 30 poster lightening presentations. In two poster sessions, 273 posters were discussed, creating numerous opportunities for scientific exchange and networking within the community. 

The Central German Plant Physiology Conference, which brings together young scientists from four universities every year, took place for the 24^th time, this year in Dresden as scheduled. In addition to providing a very important forum for presentations by early career scientists (ECRs), the conference also plays a major role in promoting general scientific exchange between neighbouring universities in the field of plant sciences. Approximately 50 participants registered with a total of 20 presentations, 15 of which were given by researchers ranging from bachelor's and master's students to doctoral candidates. Once again, the sessions were chaired by ECRs. For those, who have been participating for some time, the development of scientific projects over the years is exciting, and it is possible to follow the many advances in the particular topics. This conference is free of charge for participants, since DBG's financial support enabled us organisers to provide well-equipped coffee breaks and to provide financial support to seven actively participating students at the bachelor's or master's level as well.

The topics presented ranged from plant development to abiotic stress and biotic interactions, as well as several contributions dealing with method development. The latter inspired many participants with new ideas. Techniques included - in addition to physiology - biochemical, molecular and genetic methods. Overall, the diversity of topics and the quality of the presentations were highly praised. Since the presentations were almost exclusively given by ECRs, a great deal of data from as yet unpublished projects was presented. These were discussed in detail, with the many coffee breaks again being put to good use. The conference format, consisting of two half-days, proved successful once again, as discussions continued not only during the scientific programme and coffee breaks, but also during the joint dinner afterwards at a local brewery. Organiser Prof. Dr. Jutta Ludwig-Müller reports about the topics, new ideas and the focus of research.

Prof. Dr. Christopher Grefen and his team invite you to this year's Botanik-Tagung, International Conference of the German Society for Plant Sciences to Bochum, Germany, from September 6 to 10, 2026. The conference motto, From Industrial Past to Green Future, highlights the structural change of the Ruhr area, from coal mining and heavy industries to the increasingly important issues of climate protection, sustainability, and preservation of biodiversity, with plant sciences at the forefront of this transformation. In nine plenary lectures, internationally renowned researchers will present their latest research findings. The invited guests will travel from Great Britain, the USA, Austria, Israel, and numerous research institutions in Germany, among other places. Eighteen thematic sessions and a public evening lecture will build the scientific framework of the conference. The program will be complemented by poster presentations, workshops, and extensive opportunities for professional exchange, which will offer early career researchers (ECRs) in particular the opportunity to get to know the people behind the papers. Registration is now open. 

Important dates are: 

• Early-bird deadline: 30 April 2026
• Standard registration: 1 May – 28 August 2026 (late/onsite fees apply thereafter)
• Abstract submission deadline: 31 May 2026
• Notification of acceptance: late June – early July 2026

With 26 final theses in the plant sciences our DBG has awarded more early career plant scientists (ECRs) in the last year than ever before, since our German Society for Plant Sciences (DBG) first granted this master thesis prize at the participating universities in 2014. The topics of the theses stretched from ecology and questions of interactions with other organisms or the environment, (epi-)genetic regulation, morphological studies, enzyme reactions, protein chemistry, evolution, photosynthesis, biotic and abiotic stresses to the analysis of resistance in crops. Once again this demonstrates the diversity of the scientific disciplines that are represented in DBG. Our board especially thanks the on-site contact persons at the participating universities, who took over the sometimes not-so-easy selection process, thereby functioning as a jury.

The nominations for DBG’s three prestigious awards for aspiring early career plant scientists (ECRs) are open now. DBG members and others, please nominate suitable candidates for the Eduard Strasburger Prize, the Wilhelm Pfeffer Prize and the Horst Wiehe Prize. Awardees will be invited to present their work orally at the next International Conference of our German Society for Plant Sciences, the Botanik-Tagung. Application deadline is 26^th April 2026.

The International Symposium on Cereal Meristems and Stem Cell Systems, organised by DFG Research Unit FOR235 Cereal Stem Cell Systems: Establishment, Maintenance and Termination (CSCS), brought together around 90 scientists from 14 countries at Regensburg University, Germany, from 28^th of September to 1^st of October 2025. The Symposium was the first international scientific conference that focused on the frontiers of plant stem cell and meristem science in cereals and other crops through the presentation of cutting-edge research.  The organisers around Prof. Dr Thomas Dresselhaus and Dr. Melanie Heinrich report about keynotes, awarded contributions of early career researchers (ECRs) and their hope that this meeting will prompt further conferences in this emerging scientific discipline.

Ein alter Ginkgobaum im Botanischen Garten Marburgs ist seit mehr als hundert Jahren stiller Zeuge leiser Veränderungen im Leben dreier Menschen: eines Neurowissenschaftlers im Jahr 2020, eines Studenten im Jahr 1972 und einer Studentin im Jahr 1908. Den wie Poesie erzählten Film, mit seinen detailreichen Pflanzenaufnahmen, Zeitrafferdarstellungen und mikroskopischen Aufnahmen aus Zellen kann die stellvertretende Sprecherin unserer Sektion für Angewandte Botanik, Prof. Dr. Jutta Papenbrock, auch anderen ans Herz legen. Sie hat den Film bereits gesehen, der aktuell von Pandora-Film an die lokalen Arthouse-Kinos verliehen wird. Die Pflanzenwissenschaftlerin hofft, dass die Pflanzenvielfalt und wissenschaftlichen Details dazu animieren, die Pflanzenwelt im täglichen Leben bewusster wahrzunehmen.
