Unanimously, the member assembly decided that the emerita Professor Dr. Ulla Bonas will become new honorary member of the German Society for Plant Sciences (DBG). Proposed by DBG’s board, our president Professor Dr. Andreas Weber and honorary member Prof. Dr. Birgit Piechulla conveyed the news to Bonas, professor for Plant Genetics at Martin Luther University Halle-Wittenberg, since she unfortunately was unable to participate at our International Conference of the German Society for Plant Sciences. Our honorary member Professor Dr. Regine Kahmann summarizes in the laudation how Professor Bonas has made exceptional scientific discoveries. For example, her group was able to crack the recognition code of the newly discovered DNA binding domain in TAL effector proteins. The modular architecture of the proteins enabled the design and construction of artificial DNA-binding proteins with new specificities, which led to TALENs (Transcription activator-like effector nucleases). This was a major breakthrough to inactivate genes in eukaryotic genomes. The technological advancement cannot be underestimated and deserves the greatest recognition. TALENs would still be used today if the more-easy-to-use CRISPR Cas9-based gene editing system would not have been invented. Moreover, Bonas and her group gained major insights into the mechanisms as to how bacterial pathogens manipulate their host plants. Bonas received many prestigious awards and also serves the scientific community, e.g., as vice president of the German National Academy of Sciences Leopoldina, as Kahmann’s laudation describes, which DBG’s president Weber presented at our member assembly in Halle, Germany, on 17^th September 2024. 

Unanimously the general assembly agreed that three of us will become honorary members of our German Society of Plant Sciences (DBG) in Bonn, Germany, on August 31^st.  

• Professor Birgit Piechulla is well known as a leading plant bio chemist with a focus on volatile secondary metabolites of plant and bacteria and on circadian rhythms with many highly cited scientific papers and a textbook that is translated into many languages, as Professor Ivo Feussner points out in his laudatory speech (pdf) in Bonn. The plant science community also knows her as organizer of many conferences – for example our last Botanikertagung 2019 in Rostock – and her commitment in scientific committees has shaped a lot in the plant sciences.
• PD Dr. Klaus-J. Appenroth (Jena) will not only become a honorary member because of his tireless commitment in researching and cultivating duck weeds – a plant group that is about to become a new cultivated plant for a variety of usages – but also for his many years being the treasurer of our society. This are only a few of the achievements of Appenroth that are summarized in the laudatory text written by Professor Ingo Schubert (pdf) and presented by Professor Jutta Ludwig-Müller at our member assembly.
• Professor Widmar Tanner not only discovered the first plant sugar transporter but also made several important discoveries on the glucose uptake and transport systems, about metabolite fluxes as well as in related fields of plant cell physiology. Moreover, he initiated two independent Collaborative Research Centers (Sonderforschungsbereiche, SFB). Not only his scientific achievements but also his work in the plant science community makes him a deserved honorary member of our society, as our president Professor Andreas Weber reported in Bonn from the laudatory text that was written by Professor Ekkehard Neuhaus (pdf).

Heinz Rennenberg erbrachte herausragende wissenschaftliche Pionierleistungen zum Schwefel-Stoffwechsel der Pflanzen, zum Austausch klimarelevanter Spurengase wie etwa Methan zwischen Bio- und Atmosphäre sowie in Physiologie, Ökophysiologie und Molekularbiologie der Bäume. Über viele Jahre war er darüber hinaus Editor in Chief unserer Fachzeitschrift Plant Biology sowie Präsident der Federation of European Societies of Plant Biology (FESPB) und engagierte sich in unserer Sektion Pflanzenphysiologie und Molekularbiologie. Zudem ist er Mitglied der Nationalen Akademie der Wissenschaften Leopoldina. In der Laudatio zählen die vier antragstellenden Pflanzenwissenschaftler*innen weitere Ergebnisse von Rennenbergs Engagement und wissenschaftlichen Leistungen heraus.

Der Inhaber des Lehrstuhls für Botanik an der Universität Würzburg etablierte die seinerzeit neue Forschungsdisziplin der Ökophysiologie, in der er die Fähigkeiten von Algen, Moose und Flechten (Kryptogamen) und Gefäßpflanzen zu ergründen suchte. Lange interessierten vor allem die physiologischen, biophysikalischen und biochemischen Anpassungen der Pflanzen an Ihre Umgebung. Aufgrund seiner wissenschaftlichen Leistungen erhielt das Ehrenmitglied der DBG zahlreiche Auszeichnungen. Sein Schüler und späterer Kollege, Professor Dr. Burkard Büdel, erinnert in seinem Nachruf an Leben und wissenschaftliches Werk, Langes wertschätzendes Wesen, das anderen half wo immer es ging, und seinen hohen Anspruch an die Wissenschaftlichkeit.

Die Pflanzenphysiologin Professorin Renate Scheibe von der Universität Osnabrück und der Photosyntheseforscher Professor Hartmut Lichtenthaler sind in Kiel von den Mitgliedern der DBG zu zwei neuen Ehrenmitgliedern der Gesellschaft ernannt worden. Beide sind herausragende Forschende, haben sich für den wissenschaftlichen Nachwuchs und die DBG, insbesondere deren Sektion Pflanzenphysiologie und Molekularbiologie, stark gemacht.

Die Gesellschaft hat drei neue Ehrenmitglieder, die die Pflanzenwissenschaften bereichert und sich für die  Pflanzenforschung stark gemacht haben. Dieses Jahr wurde die Ehrung drei Persönlichkeiten zuteil: Professorin Regine Kahmann, Professor Ulf-Ingo Flügge und Professor Peter Schopfer. Lesen Sie in den Laudationes, die anlässlich deren Ernennung auf der Botanikertagung in Tübingen gehalten wurden, welche exzellenten Forschungsergebnisse die drei über Pilz-Pflanze-Interaktionen, über Stofftransport und Stoffwechselwegen oder zur Wachstumsphysiologie erzielten und in welchen Lehrbüchern sie botanisches Wissen vermittelten.
