Sorry, in German only

Eigentlich wollten wir Neues bei der 35. Tagung Molecular Biology of Plants (MBP2022) ausprobieren. Denn aufgrund der Schließung der langjährigen Tagungsherberge in Dabringhausen, mussten die Organisator*innen einen neuen Veranstaltungsort finden. Das gelang im vergangenen Sommer, als die Sportschule Hennef - ansonsten Heimat der sportlichen Elite - als neuer Konferenzort gewonnen werden konnte. Wenn auch nicht ganz so abgeschieden wie das Haus Maria in der Aue, so versprach die Sportschule doch, eine ähnliche Tagungsatmosphäre mit viel Raum für wissenschaftlichen Austausch zu bieten, so wie früher in Dabringhausen. Doch leider machte dem die Pandemie - wie auch im Jahr zuvor - einen Strich durch die Rechnung, so dass auch MBP2022 wieder nur online stattfinden konnte. Das Organisationsteam mit Marcel Quint (Halle), Andreas Meyer (Bonn), Ute Höcker (Köln) und Rüdiger Hell (Heidelberg), technisch verstärkt durch Fabian Haas (Marburg), berichtet von der seit 1988 jährlich stattfindenden Konferenz der Sektion Pflanzenphysiologie und Molekularbiologie, zu der sich mehr als 300 Teilnehmende gleichzeitig am 15. und 16. Februar zusammenschalteten. Neu waren auch ein wissenschaftlicher Preis sowie eine Out of Academia Session.

Invitation to Botanik-Tagung 2022

Conference flyer for the upcoming Botanik-Tagung 2022 (pdf)

Prof. Dr. Andreas Meyer and his organizing committee invite all plant scientists to take part in Botanik-Tagung, International Conference of the German Society for Plant Sciences, in Bonn, Germany. 

Dear colleagues and friends,

We are back! Delayed by one year, we are now able to organize and run the next International Conference of the German Society for Plant Sciences (Botanik-Tagung 2022) as an in-person conference. On behalf of the German Society for Plant Sciences, I would like to invite you to Bonn for a lively exchange on the latest discoveries in plant sciences.
For more than 200 years, plant research has been a key research area at the University of Bonn, both at the basic level and as an applied science in agriculture. Plant research in Bonn is connected with names like Julius von Sachs, Wilhelm Pfeffer, Robert Caspary and of course Eduard Strasburger, who all worked in Bonn and set footprints that we still see today. Drawing on the spirit of translational research that has been established in Bonn for two centuries, the organizing committee put together a conference program that emphasizes the importance of Plant Sciences for a Sustainable Future in 8 plenary talks, 21 symposia and a number of workshops. Together with my colleagues, I would be thrilled if you take the opportunity to participate in this in-person meeting and actively engage in presenting and discussing current work
and ideas in Bonn. The City of Bonn welcomes you at the birthplace of Ludwig van Beethoven on the Rhine, a city with plenty of history and today a forward-looking, colorful, and charming international location.
See for yourself what variety is offered to you here both in science and beyond!
Prof. Dr. Andreas Meyer

Über 350 Teams von Universitäten aus der ganzen Welt haben am diesjährigen iGEM-Wettbewerb (international Genetically Engineered Machine competition) teilgenommen. Den ersten Platz ergatterte das Team aus Marburg: Mit ihrem Projekt OpenPlast haben 17 Studierende unterschiedlicher Fachdisziplinen der Philipps-Universität Marburg eine Technologie präsentiert, welche die Entwicklung neuer, klimaresistenter Nutzpflanzen rasant beschleunigen kann. Dazu setzte das Team auf Photosynthese treibende Chloroplasten, was einige Vorteile für die finale Anwendung in Nutzpflanzen bietet. Genetische Veränderungen im Chloroplasten werden nicht durch Pollen übertragen und erhöhen die biologische Sicherheit. Mit diesem Ansatz holte es den Gesamtsieg. Außerdem kommunizierte es die Ergebnisse an Schulen und in der Landwirtschaft. Warum das Team die Jury überzeugte und was ihr neues System auszeichnet, schildern die Betreuerinnen und die Studierenden hier.

Awarded: how proteins regulate a central gene switch in seedlings

Dr. Katharina Bursch receives this year’s Best Paper Prize in plant sciences from the German Society for Plant Sciences’ (DBG) Wilhelm Pfeffer Foundation. The prize is endowed with 1,000 Euros. “Dr. Bursch has demonstrated the existence and mode of action of cofactors that influence the growth of the seedlings’ stem after emerging from the soil into the light, more than 20 years after these cofactors were predicted”, highlights the foundation’s board. In her work she showed how a universal transcription factor like HY5 (LONG HYPOCOTYL 5) can activate transcription of its target genes through the interaction with cofactors. Dr Bursch and her colleagues from the working group of Dr. Henrik Johansson (Freie Universität Berlin), together with collaboration partners from the UK and Switzerland, identified the B-Box proteins BBX20, BBX21 and BBX22 that allow HY5 to fulfill its function as a positive regulator of photomorphogenesis in the model plant Arabidopsis thaliana. With the identification of these cofactors, published in Nature Plants (Identification of BBX proteins as rate-limiting cofactors of HY5 https://doi.org/10.1038/s41477-020-0725-0), the understanding of how a master transcriptional regulator gains specificity and dynamicity was extended. Dr. Bursch will receive her certificate in September next year at the Botanik-Tagung (International Conference of the German Society for Plant Sciences) in Bonn, Germany. The prize money was already given to her.

Open Statement on the Regulation of Genome Edited Plants and Crops

The EU and New Zealand differ from most other countries and their regulations for precision breeding techniques (see Schmidt, Belisle, Frommer (2020), EMBO Rep 2020, e50680, https://doi.org/10.15252/embr.202050680)

132 European research institutes and science associations – with DBG being one of them - strongly recommend to the European Council, European Parliament and the European Commission to revise the existing directive for precision breeding, also known as genome editing. This is not only important for recovery from the COVID-19 crisis but also since genome-editing offers many solutions for a fast, relatively simple and much more directed way to create resilience to climate change compared to previous breeding techniques. Moreover the breeding of plants that are less dependent on fertilizers and pesticides is more efficient. Use of these methods preserves natural resources of our planet and supports to achieve the Sustainable Development Goals of the United Nations as well as the Green Deal of the EU. The European Sustainable Agriculture through Genome Editing (EU-SAGE) Network, under which the institutions named above are unified, recommends the European Commission to endorse this message for the benefit and welfare of all EU citizens and to adapt the current regulations to use genome-editing for crop and plant breeding to recent scientific results. In its Open Statement the EU-SAGE network cites scientific studies that demonstrate the successful creation of genome-edited plants with resilience to climate change and resistance against pests and diseases and therefore higher yields and revenues. Other studies have proven to reduce the dependency on pesticides by improving resistance against diseases in rice, wine, wheat, and grapefruit. In addition precision breeding accelerates the introduction of healthy traits into vegetables and fruits, as studies have shown.

Review: Likely roles of the distinct cytosol- and plastidlocated Glutamine synthetase isoenzymes in A. thaliana

Arabidopsis thaliana revels a species-specific functional redundancy of the Glutamine Synthetase gene family, having an isoenzyme compensation mechanism that prevents gene loss of function.

In their review "Glutamine synthetase: an unlikely case of functional redundancy in Arabidopsis thaliana" the authors Moreira, Coimbra and Melo integrate analyses on the likely roles of the distinct cytosol- and plastidlocated Glutamine synthetase (GS) isoenzymes in the model plant, highlighting the redundancy of the GS gene family specifically occurring in this plant. This is in contrast to GS isoenzymes that were observed in nitrogen metabolism in species like Oryza sativa and Zea mays.

Review: Hydrogen sulphide - an emerging regulator of plant defence signalling

Hydrogen sulfide enhances plant immunity against invading pathogens.

A growing body of evidence indicates potential role of H2S in plant defence, particularly against bacterial and fungal pathogens. Recent studies suggested that the gaseous signalling molecule participates in plant defence potentially by

  1. regulating glutathione metabolism,
  2. inducing expression of pathogenesis-related (PR) and other defence-related genes,
  3. modulating enzyme activity through post-translational modifications, and
  4. interacting with phytohormones such as jasmonic acid, ethylene and auxin.

The authors Choudhary, Singh, Khatri, and Gupta discuss the biosynthesis, metabolism and interaction of H2S with phytohormones, and highlight evidence gathered so far to support the emerging roles of H2S in plant defence against invading pathogens.

Review: How H2S mitigates adverse effects of abiotic stress

Application of exogenous hydrogen sulfide induces changes, at the biochemical and molecular level, that mitigate the detrimental effects of diverse abiotic stressors.

Since signalling molecules like hydrogen sulfide (H2S) play a crucial role in mitigating the adverse effects of environmental stresses in plants it is important to understand the several physiological and biochemical mechanisms. The authors review recent advances in understanding the beneficial roles of H2S in conferring multiple abiotic stress tolerance in plants. And discuss the interaction and crosstalk between H2S and other signal molecules and highlight some genetic engineering-based current and future directions.

Seed biologists beware: Estimates of initial viability based on ungerminated seeds at the end of an experiment may be error-prone

It is recommended to determine initial seed viability at the start of the experiment, since prolonged duration of ungerminated seeds in germination treatments can lead to loss of viability.

In his viewpoint paper Author Lamont asks for caution against the routine use of end-of-trial germination and viability of ungerminated seeds as an estimate of initial viability in determining germination success of various treatments. He analyses Leucadendron species and in his paper also explores ways to deal with the problem and to preference estimates of initial viability to be undertaken on a separate sample of seeds concurrently with the experiment as this avoids the risk of seed death during the trial.

Does plant leaf flammability converge with increasing radiant heat flux in Australian fire-prone woodlands?

Leaf flammability patterns are significantly affected by increasing radiant heat flux, with important implications for integrating leaf flammability into wildfire models.

From their findings the authors Krix, Murray and Murray conclude that leaf flammability is significantly affected by increasing radiant heat flux. In their paper “Increasing radiant heat flux affects leaf flammability patterns in plant species of eastern Australian fire-prone woodlands” they suggest that of the flammability attributes assessed, flame duration is the most informative to include in wildfire models which explicitly consider species’ flammability, given that differences among species in flame duration are maintained across a radiant heat flux gradient.

How seedling's shoot:root ratio, moiture gradient and species niche are associated

The seedling shoot:root ratio has a general adaptive role of in relation to the species niche position on the soil moisture gradient in temperate grassland species.

In their research paper "Shoot:root ratio of seedlings is associated with species niche on soil moisture gradient", Mašková, Maternová, Tĕšitel explore evolutionary adaptations determining plant early growth strategies in 15 herbaceous genera of temperate grasslands differing in their requirements for soil water availability. Linear mixed-effect models identified the length-based shoot:root ratio of seedlings was positively associated with soil moisture requirements in a congeneric species comparison. Nitrogen and phosphorus seed concentrations had an additional negative effect on the shoot:root ratio. Neither of these trends was found for the mass-based shoot:root ratio.
They thus demonstrated for the first time that there might be a general adaptation modifying the seedling shoot:root ratio according to the species niche position on the soil moisture gradient in temperate grassland species across a broad range of angiosperm phylogeny. This adaptation seems to be affected by seed mineral nutrient reserves and may
operate in parallel to the well-known phenotypic plasticity.

Review: Genome-wide identification studies – A primer to explore new genes in plant species

Genome-wide studies provide an initial framework to identify gene families in plant genomes and further characterize their gene structures, evolutionary relationships, protein interactions, gene expression patterns in various tissues and predict putative gene functions using various computational tools.

Genome data have accumulated rapidly in recent years, doubling roughly after every 6 months due to the influx of next-generation sequencing technologies. A plethora of plant genomes are available in comprehensive public databases. This easy access to data provides an opportunity to explore genome datasets and recruit new genes in various plant species not possible a decade ago. In the past few years, many gene families have been published using these public datasets. These genome-wide studies identify and characterize gene members, gene structures, evolutionary relationships, expression patterns, protein interactions and gene ontologies, and predict putative gene functions using various computational tools. Such studies provide meaningful information and an initial framework for further functional elucidation. The review by I. Safder, G. Shao, Z. Sheng, P. Hu, and S. Tang provides a concise layout of approaches used in these gene family studies and demonstrates an outline for employing various plant genome datasets in future studies.

Review: Biotechnology of virus eradication and plant vaccination in phytobiome context

For successful control of viral diseases of grapes, the focus of research should shift from the complete eradication of viruses to a detailed study of the RNA pool of naturally occurring grape viruses, the efficient in vitro vaccination systems and possible tools to protect beneficial phytobiome from obliteration.

A plant’s associated biota plays an integral role in its metabolism, nutrient uptake, stress tolerance, pathogen resistance and other physiological processes. Although a virome is an integral part of the phytobiome, a major contradiction exists between the holobiont approach and the practical need to eradicate pathogens from agricultural crops. In their review, V. Oberemok, K. Laikova, I. Golovkin, L. Kryukov and R. Kamenetsky-Goldstein discuss grapevine virus control. But the issue is also relevant for numerous other crops, including potato, cassava, citrus, cacao and other species. Grapevine diseases, especially viral infections, cause main crop losses. Methods have been developed to eliminate viruses and other microorganisms from plant material, but elimination of viruses from plant material does not guarantee protection from future reinfection. Elimination of viral particles in plant material could create genetic drift, leading in turn to an increase in the occurrence of pathogenic strains of viruses. A possible solution may be a combination of virus elimination and plant propagation in tissue culture with in vitro vaccination. In this context, possible strategies to control viral infections include application of plant resistance inducers, cross protection and vaccination using siRNA, dsRNA and viral replicons during plant ‘cleaning’ and in vitro propagation. The experience and knowledge accumulated in human immunization can help plant scientists to develop and employ new methods of protection, leading to more sustainable and healthier crop production.

Review: Auxin in plant development - structure, signalling, regulation and response mechanisms

Auxin-integrating chemical and molecular processes are involved in plant growth and development, regulated by the synthesis and distribution of the phytohormon.

Auxins as plant hormones play a central role in controlling growth and development across different environmental conditions. In their review G. L. B. Gomes and K. C. Scortecci summarise recent advances in understanding the biosynthetic pathways, both dependent and independent of tryptophan, highlighting the intermediate indole compounds (indole-3-acetamide, indole-3-acetaldoxime, indole-3-pyruvic acid and tryptamine) and the key enzymes for auxin biosynthesis, such as YUCs and TAAs. In relation to the signalling cascade, it has been shown that auxins influence gene expression regulation by the connection between synthesis and distribution. Moreover, the molecular action of the auxin response factors and auxin/indole-3-acetic acid transcription factors with the F-box TIR1/AFB auxin receptors regulates gene expression. In addition they also demonstrate the importance of microRNAs in the auxin signalling pathway and their influence on plant plasticity to environmental fluctuations. Finally, this review describes the chemical and biological processes involving auxins in plants.

Review: Drought and crop yield

Drought stress negatively affects crop plants by reduced transpiration and root architecture leading to dehydration and yield penalty.

The review summarizes the effects of drought stress on crop plants and relates the dehydration-dependent yield penalty to the harvested organ and tissue. The control of shoot transpiration and the reorganization of root architecture are of core importance for maintaining proper plant water relationships. Upon dehydration, the provision and partitioning of assimilates and the uptake and distribution of nutrients define remaining growth activity. Domestication of crops by selection for high yield under high input has restricted the genetic repertoire for achieving drought stress tolerance. Introgression of suitable alleles from wild relatives into commercial cultivars might improve the ability to grow with less water. As the authors KJ Dietz, C Zörb, and CM. Geilfus,conclude, future research activities should focus more on field studies in order to generate more realistic improvements to crops. Robotic field phenotyping should be integrated into genetic mapping for the identification of relevant traits.

How vegetation, native and non-native bees are linked to vine production

Pollination is provided by biodiversity and maintains global food production. When we look to vineyards surrounded by intermediate native vegetation, we can observe a balance between the resource availability from vineyards and native vegetation.

There are positive relationships between vineyard production and native vegetation in the landscape. The native fragments inserted within landscapes with more native vegetation area exhibited better parameters of vine production and quality. Apis and non-Apis (such as flies and small bees) floral visitors, known to have different effects on vine pollination, could hypothetically provide variation in vine production and quality. Considering a near 20% native vegetation increment, there was an enhancement, on average, of ten-fold more berries per bunch, the changing physical and chemical fruit traits by vegetation increment could also increase the aggregate value of vines and the value of pollination services in the economy.

Factory of molecules

In Ballota acetabuolosa, peltates and long-stalked capitates are responsible for terpene production. γ-Muurolene, β-caryophyllene and (E)-nerolidol prevail in the foliar and floral volatile organic compound (VOC) profiles.

Within the Open Science project a multidisciplinary study analyzed Ballota acetabulosa (L.) Benth. at the Ghirardi Botanic Garden (Toscolano Maderno, BS, Italy). Micromorphological and histochemical investigations were performed on the secreting structures of the vegetative and reproductive organs under light, fuorescence and electronic microscopy. Concurrently spontaneously emitted volatiles from leaves and flowers were examined. Four trichome morphotypes were identified: peltate and short-stalked, mediumstalked and long-stalked capitate trichomes, each with a specific distribution pattern. The histochemical analysis was confirmed using ultrastructural observations, with the peltates and long-stalked capitates as the main sites responsible for terpene production. The head-space characterization revealed that sesquiterpene hydrocarbons dominated both in leaves and flowers, with c-muurolene, b-caryophyllene and (E)-nerolidol as the most abundant compounds. Moreover, a comparison with literature data concerning the ecological roles of the main compounds suggested their dominant roles in defence, both at the leaf and flower level.
