About us

The section Natural Products brings together scientists of several generations who are interested in various aspects of natural products research ranging from biosynthesis over physiological and ecological function and evolution to biotechnological production of natural plant products. The sections furthers scientific exchange between its members and supports early career scientists.


Members of the section receive information about activities of the section, section meetings, workshops and relevant job announcements via Email.

Scientific meetings

The section Natural Products meets every second year (alternating with Botanikertagung) for a symposium. These meetings provide a nice platform for scientific exchange and  are especially devoted to young scientists. PhD students and postdocs have the opportunity to present their work, to discuss it in an informal atmosphere and to build their scientific network.

The next section meeting will be held in Jena, Germany, on October 02-04, 2020.


Members pay a yearly fee of 10 €. Members of our head organisation, Deutsche Botanische Gesellschaft (DBG), can become a member of our section through the DBG website.

Please contact the section's speakers if you have questions, suggestions or requests.

Klebsormidium: Pendler zwischen scheintot und Wiedererwachen ist Alge des Jahres 2018

Sorry, in German only

Die mehrzellige Grünalge Klebsormidium lebt an Land an solchen Orten, wo keine andere Pflanze mehr wachsen kann. Als weltweit verbreiteter Pionier schafft sie neue Lebensräume, was Farmer und Wüstenanrainer nutzen. Forscher interessieren sich für ihre biologischen Tricks, wie sie zwischen leblos und Wiedererwachen hin und her wechselt. Die Professoren Andreas Holzinger (Universität Innsbruck) und Ulf Karsten (Universität Rostock) erforschen in enger Kooperation die Fähigkeiten, die die Alge vor Austrocknung und gefährlichen UV-Strahlen schützt. Beide sind Mitglieder der Sektion Phykologie der Deutschen Botanischen Gesellschaft (DBG), die Klebsormidium zur Alge des Jahres 2018 kürte.

Alga of the year 2017: Blue-Green Rock Dweller – ancient and still a pioneer

The algal researchers of the DBG nominated the Blue-Green Rock Dweller Chroococcidiopsis for the alga of the year 2017. The single celled organism lives inside rocks and lichens, survives extreme climatic conditions and makes hostile environments accessible – today and most likely thousands of millions of years ago as well. While doing so, it paved the way for plants and animals. The blue-green rock dweller, belonging to the cyanobacteria lives like all algae, from sunlight, and is of great interest to ecologists, biotechnologists, and desert- and space researchers. It is the favorite research subject of Prof. Dr. Burkhard Büdel from the University of Kaiserslautern, who has been investigating it for more than 30 years. He is a member of the Phycology Section of the German Society for Plant Sciences, DBG, in which the algal researches are organized and who nominate this year an alga of the year for the tenth time this year.

Sea Ice Alga Melosira arctica – winner or loser of climate change?

One of the most important microalgal species from the Arctic Ocean, Melosira arctica, has been nominated “Alga of the Year” by the German Phycology Section of the DBG. Scientists will use Melosira as a model to understand consequences of climate change. “Currently no one can foresee whether Melosira will benefit or suffer from the melting of sea ice, and nobody knows why it is so productive under such hostile conditions,” says biologist Klaus Valentin from the Alfred Wegener Institute (AWI). He is a Member of the Phycological Section within the Germany Botanical Society, which selected Melosira as Alga of the year 2016.

Alga of the year 2011: Fragilariopsis cylindrus loves the extremes

Algal researchers from the Phycology Section have declared the diatom Fragilariopsis cylindrus alga of the year 2011. ‘We are fascinated by this species because it can survive and even reproduce within the ice of the polar seas, one of the most extreme habitats on earth’ argues Professor Dr Peter Kroth from the University of Konstanz. Kroth is Chair of the Phycology Section of the German Botanical Society.

Section Meeting 2015

In the course of the Botanikertagung „From Molecules to the Field“ in Freising, Germany, the section will convene for the lecture of keynote speaker Dr. Pamela Soltis (University of Florida, Monday, 8 31st 2015, 11:15 a.m.), sessions “Biodiversity” (chair: Christian Wirth, Monday, 8 31st 2015, 2:30 a.m.) and “Systematics” (chair: Susanne Renner, Wednesday, 9 2nd 2015, 6:15 p.m.) and a workshop/symposium entitled “Chromosomal and biogeographic evolutionary patterns in plants” (Monday, 8 31st 2015, 8:00 p.m.). We hope that the enticing area and diverse meeting contents will encourage many systematists to join the Botanikertagung.

Sorry, at present we have no English version of the statutes. Please refer to the German version.

About us


The Section promotes Mycology including Lichenology in all aspects. It organizes a workshop every other year in alternation with the conferences of the Botanikertagung of the DBG.

New Name of the Section

On the member assembly on October 1st 2013 during the Botanikertagung at Tübingen, Germany, the Section decided to change its name into „Section for interactions (former Section of mycology and lichenology)”. Members also agreed to keep this name for two years from now on.


Archives of former meetings


Members receive direct information about the activities of the Section during the Botanikertagung mainly concerning symposia and workshops.

At the moment membership in the section is free of fees.

How to become a member?

Prerequisite for a membership in the Section is a membership in the German Botanical Society (DBG). To become a member, please write an informal letter to the speaker of the Section.


The Section has its onw statutes besides the statutes of the DBG. Sorry, at present we have no English version of our statutes. Please refer to the German version of the statutes (pdf file).

Meeting 2013

All members are invited to join the meeting of the Section on 1st October 2013 during the Botanikertagung in the Kupferbau building, University of Tübingen, Germany.

Section Meeting 2012

Scientific meeting of the Section took place in co-operation with the German Mycological Society: 1st - 7th October 2012 at Kloster Drübeck, Harz, Germany. The scientific part of the programm took place on October 1st to 3rd.

Section Meeting 2014

Section Meeting 2013

Professor Olaf Bininda-Emonds and Professor Dirk Albach from the departments „Biodiversität und Evolution der Pflanzen“ und „Systematik und Evolutionsbiologie“ of Oldenburg University, Germany invited to "The time for phylogenetics - inferring and applying timetrees in evolutionary biology". The symposium took place at Oldenburg from 22nd to 24th November 2013 ( [5]) and focused on:

  • New advances in molecular clocks (Prof. Dr. Susanne Renner, Munich)
  • Fossil dating and calibrations (Prof. Mike Benton, Bristol)
  • Bayesian estimation of species divergence times (Dr. Mario dos Reis, London)
  • A unified framework for inferring speciation and extinction rates from phylogenies with fossils (Dr. Tanja Stadler, Zurich)
  • Timetrees and the historical biogeography of the “Rand Flora” (Dr. Isabel San Martin, Madrid)
  • Co-evolution and timetrees (Dr. Chuck Bell, New Orleans)

The DBG supported the attendance of jung scientists.

Groups of Experts

Members of the DBG are welcome to found Sections in specialized fields (see §6, statutes). In addition to the Congress "Botanikertagung" the Sections organize scientific symposia in their specific field of work. The following Sections have been appointed by the Board:

Membership in the Sections

Affiliation with a Section is not obligatory for members of the German Botanical Society (DBG). In addition to the membership fee for the DBG, some Sections charge an additional annual membership fee to be able to fulfill their mission. However, for new members, a separate Section membership for up to three years is possible, before finally also joining DBG.

About us in brief

The Section promotes science and higher education in physiology, biochemistry and molecular biology of plants. It supports communication among its members via a mailing list and supports young scientists.

Every year the Section organises a scientific meeting, the wellknown "Conference of Molecular Biology of Plants". On its website the Section Plantphysiology and Molecular Biology posts their meetings and conferences, lists the advantages of being a member and presents actual information via its twitter account.
