Sorry, report in German only

Ihre Ergebnisse und Forschungsarbeiten über die vielfältigen Interaktionen zwischen (Nutz-)Pflanzen und Mikroben tauschten knapp 20 angehende Wissenschaftler*innen aus drei Ländern im Februar in Königswinter aus. Die Tagung thematisierte sowohl Symbiosen als auch Pflanzen-Pathogene. Eine externe Vortragende berichtete über Jobs außerhalb von Universtäten und ein Mitmach-Workshop ermunterte die Teilnehmenden über Chancen und Risiken der öffentlichen Kommunikation ihrer Forschungsthemen nachzudenken. Einig war man sich, dass es ein großes Interesse an der Interaktions-Forschung geben sollte, da diese dazu beiträgt, anwenderfreundliche Lösungen für den Erhalt der Pflanzengesundheit und der Ertragsmengen zu bieten. Die fünf Organisator*innen des Eduard-Strasburger-Workshops der DBG von angehenden Nachwuchskräften der Sektion für Interaktionen für andere junge Pflanzenwissenschaftler*innen fassen die Veranstaltung zusammen.

Cathrin Manz (Philipps-Universität Marburg)

Cathrin Manz's Master thesis was awarded with the Prize for the Best Plant Science Master Thesis, which was carried out at Philipps-Universität Marburg in the year 2019.

Title: "Diversity assessment of the ectomycorrhizal genus Russula in tropical montane forests in Panama"

For the first time Manz investigated the diversity of Russula species (“brittlegills”) in the mountain rainforests of Panama. More than 45 species were discovered for the first time for Panama with many of them new to science.

The diversity of ectomycorrhizal fungi in the tropics is still largely underexplored, even though they constitute a key component of tropical montane forest ecosystems. In this study, 106 collections of the genus Russula (“brittlegills”) were collected in Chiriquí, Panama and described as fresh fruiting bodies. The samples were analysed with phylogenetic methods using the universal fungal barcode ITS. The resulting phylogenetic tree revealed a total number of 90 Russula species in Panama of which 47 species were newly recorded for this country. Among these samples are many putatively new species. A selection of four new Russula species from subsection Roseinae were analysed morphologically by light and scanning electron microscopy in the context of the master thesis. Five patterns for ectomycorrhizal partners and geographic distribution were revealed. Facing habitat loss and climate change, it is today more than ever necessary to collect and store specimens with associated data and to openly share these resources. Otherwise many species will become extinct unnoticed.

Erstmals haben wir unseren neuen Preis für Wissenschaftskommunikation verliehen. Die Auszeichnung ging an Robert Hoffie, Doktorand am Leibniz-Institut für Pflanzengenetik und Kulturpflanzenforschung in Gatersleben (IPK). Als @ForscherRobert engagiert sich der Pflanzenforscher in Sozialen Medien, erklärt geduldig den Stand der Forschung über moderne Methoden in der Pflanzenforschung und scheut - wenn es nötig ist - auch nicht die Auseinandersetzung mit Politikern.
„Wenige andere Pflanzenwissenschaftler sind so engagiert in den sozialen Netzwerken wie Robert Hoffie“, sagte Prof. Dr. Stefan Rensing, Sprecher der Sektion. Er wünsche sich mehr Wissenschaftler wie Robert Hoffie, die unsere Themen in die Öffentlichkeit tragen und unsere Sichtbarkeit erhöhen.

Die Auszeichnung verlieh die Sektion am 13. Februar, während der jährlichen Konferenz Molecular Biology of Plants in Dabringhausen (Nordrhein-Westfalen). „Der Preis ist für mich Motivation und Bestätigung zugleich“, erklärte Robert Hoffie. Denn der aktuelle Stand der Wissenschaft sei das Beste, was wir haben, um zu fundierten Einschätzungen zu kommen. "Worauf, wenn nicht darauf, sollen wir unsere Einschätzungen denn künftig sonst stützen?“ fragt sich der 28-Jährige. Zwar könne die Wissenschaft nicht die Politik ersetzen, werde aber selbst immer mehr zu einem gesellschaftlichen Akteur.

    Erik Pischke's Master thesis was awarded with the Prize for the Best Plant Science Master Thesis, which was carried out at Rostock University in the year 2019.

    Title:

    The role of the leucine biosynthesis for Pb tolerance in Arabidopsis thaliana

    He found out that the heavy metal lead can differentially affect the growth of ecotypes and mutants of A. thaliana and that an enzyme involved in leucine biosynthesis is essential for Pb tolerance.

    Natural variance of lead tolerance was tested for different ecotypes of A. thaliana to identify molecular mechanism involved in Pb tolerance. Liquid seedling assays were performed, and root lengths were measured upon exposure to Pb. Genome wide association analysis had pointed at enzymes of leucine biosynthesis. Therefore, respective mutants were studied. They showed strong Pb hypersensitivity in comparison to the reference wildtype. A partial rescue of the lead-affected phenotype was observed when leucine was supplied to the medium. Upcoming experiments will aim at understanding the genetic and metabolic reasons for the impacts that Pb has on the leucine biosynthesis in A. thaliana.

    Nicola Schmidt s Master thesis was awarded with the Prize for the Best Plant Science Master Thesis, which was carried out at Technical University Dresden in the year 2019.

    Title:

    Characterisation of the endogenous phytopararetrovirus beetEPRV3 in the sugar beet genome (Beta vulgaris), a new member of the florendoviruses within the Caulimoviridae family

    For the first time, the three endopararetrovirus families within the sugar beet genome were described and analysed focusing on the family beetEPRV3. The element structure turned out to be characteristic for the respective beetEPRV family, pointing to specific evolutionary scenarios. Further, the viral sequences were found to be located within highly AT-rich heterochromatin, which provides an explanation for lacking virulence of beetEPRVs.

    Endopararetroviruses (EPRVs) are a widespread component of animal and plant genomes as a result of the integration of the viral DNA. A reactivation can cause devastating diseases, as it is known for tobacco or petunia. Using comprehensive bioinformatic methods, in this work the EPRVs within the sugar beet genome were identified and assigned to the florendoviruses, which is an abundant genus within the Caulimoviridae. The element structure was reconstructed for all three beetEPRV families. Two families (beetEPRV1 and beetEPRV3) show intact copies, whereas the third family (beetEPRV2) is arranged in a more fragmented manner. The family beetEPRV3 was furthermore analysed using molecular biological and cytogenetic methods like Southern hybridisation and fluorescent in situ hybridisation. It turned out that EPRVs belonging to this family accumulate in tight, repetitive and therefore mostly inaccessible DNA regions, allowing them to escape the host’s elimination mechanisms. These findings may help to understand how EPRVs keep their virulence in some hosts over long periods.

    Paul David Grünhofer (Bonn University)

    Paul David Grünhofer's Master thesis was awarded with the Prize for the Best Plant Science Master Thesis, which was carried out at Rheinische Friedrich-Wilhelms-Universität Bonn in the year 2019.

    Title:

    Formation and chemical composition of suberin in poplar roots

    Grünhofer analysed spatiotemporal suberin deposition in poplar roots and its chemical composition. Most parts of the results comprise control as well as osmotic stress conditions.

    Plants employ suberization of root tissue as mechanism of protection against various biotic and abiotic environmental stresses. The tissue-specific formation of suberin under control and stress conditions has been investigated by use of in-vitro tissue culture, hydroponics, fluorescence microscopy and gas chromatography. The main focus of this thesis was to establish a scientifically standardized and reproducible method to grow and treat poplar roots with a variety of different stresses, in order to lay a solid foundation for future research. In addition to that it could already be shown by use of fluorescence microscopy that a treatment of the roots with a mild osmotic stress ( 0.4 MPa) resulted in a shift of the onset of suberization towards the root tip, if compared to control conditions. An analytical preparation and examination of the harvested roots by gas chromatography showed a remarkable overlap of the suberin composition to that of the commonly used model organism Arabidopsis thaliana. A quantitative evaluation to answer the question if the mild osmotic stress in fact does induce an increased suberization of the root tissue could not be answered within this work due to limited time. However, answering this question as well as the examination of more severe osmotic stresses (-0.6 MPa and -0.8 MPa) and the treatment of roots with salt stress will follow in the seamlessly started dissertation. These topics are especially interesting due to rising temperatures in the future, which will make water (represented by osmotic stress) and thereby caused salt stress an even more prominent problem in our soils

    Nathalie Hering's Master thesis was awarded with the Prize for the Best Plant Science Master Thesis, which was carried out at KIT Karlsruhe in the year 2019.

    Title:

    In-situ hybridization in Salvia flowers and closely related Lamiaceae for the detection of developmental genes

    She detected an unexpected occurrence of B-class identity genes in the ovary of adult Salvia flowers and closely related Lamiaceae

    The flower is an evolutionary key innovation that makes a major contribution to the conservation of the species, as a specialized flower-pollinator interaction is the key to preserve the genetic lineage for many species. Within the flower development, there exists so-called "Genes of Speciation", which are significantly involved in producing reproductive barriers. From this, the debate about the species concept could be resolved, as an analysis of these genes could allow a systematically correct classification of the species. In order to understand the flower development in Salvia and closely related Lamiaceae, the temporal and spatial expression pattern of participating homeotic genes must be considered comparatively. Within this work, the expression of the B-class developmental genes GLOBOSA (GLO) and DEFICIENS (DEF) was investigated qualitatively and quantitatively as well as with the help of in-situ hybridization (ISH) in adult Salvia flowers as well as closely related Lamiaceae. ISH is a molecular biology method for the specific detection of nucleic acids in the cell of histological sections in vivo. By applying this method, the developmental genes GLO and DEF could be successfully localized via ISH in the ovary and stamen of flowers of the Lamiaceae.

    The occurrence of the B-class identity gene GLO in the stamens corresponds to the ABC model according to Coen and Meyerowitz. The unexpected localization of the two developmental genes GLO and DEF in the ovary might indicate an evolutionary young, unknown protein or point to a repression of the developmental genes by an unknown microRNA in the fourth whorl. The occurrence of the developmental genes in flowers is confirmed by a qualitative and quantitative gene expression analysis. Accurate temporal expression patterns of the developmental genes could not be detected, only that these genes occur more frequently in late developmental stages of flowering. However, the presence of DEF in the leaf implies an early involvement in the combinatorial network of flower development, in addition to its proper function as a B-class identity gene.

    Mary Beyer (Salzburg University)

    Mary Beyer's Master thesis was awarded with the Prize for the Best Plant Science Master Thesis, which was carried out at Salzburg University in the year 2019.

    Title

    Is heavy metal hyperaccumulation in Noccaea caerulescens acting as a defence mechanism against herbivores?

    Mary Beyer found out that accumulated heavy metals can have a deterring effect on herbivores, supporting the “elemental defence hypothesis”. However, the degree of this effect depends largely on the type of heavy metal and the species of herbivore as the feeding experiments showed.

    The aim of this thesis was to provide new insights to the “elemental defence hypothesis”. According to this hypothesis, heavy metals act as a defence mechanism, by deterring or killing herbivores and pathogens, which led to a higher accumulation in certain plants (hyperaccumulators). Four types of herbivores (Arion vulgaris, Vanessa cardui, Plutella xylostella and Pieris rapae) were offered plants of the hyperaccumulator Noccaea caerulescens, treated with different concentrations of nickel and zinc, in a free choice feeding trial. The feeding damage on each plant was determined and thus it was assessed if nickel and/or zinc had any effect on the herbivores feeding behaviour.

    The results support a significant correlation of feeding preferences and foliar zinc concentrations, reducing herbivory by up to 20%. However, this was not the case for foliar nickel concentrations, though a tendency of some herbivores preferring low levels of nickel could be observed. This shows that the effect of accumulated heavy metals on herbivory depends largely on the type of metal and species of herbivore.

    Jannes Höpke's Master thesis was awarded with the Prize for the Best Plant Science Master Thesis, which was carried out at Carl von Ossietzky-Universität Oldenburg in the year 2019.

    Title:

    The intricate species boundary between Veronica spicata and V. orchidea (Plantaginaceae)

    For the fist time a systematical comparison regarding missing data in combination with missing allele-dosis-information for population genetical methods like PCA/PCoA and STRUCTURE was conducted. Moreover, genetical material from the type localities of V. barrelieri subsp. crassifolia und V. tzesnae was analysed for the first time in this study.

    The aim was to analyse the potentially hybridising species Veronica spicata and V. orchidea (Plantaginaceae) regarding their species boundary. Therefore, both species and morphologically similar species were analysed using Genotyping-by-Sequencing (GBS). The same question was already analysed by Bardy et al. (2011) using AFLP data but we were not able to completely confirm their results. To get a better understanding of how mixed ploidy-levels, the influence of missing data, and missing allele-dosis-information influence population genetical analyses, simulations and analyses of GBS data were conducted to reveal the reasons for the observed differences. Hereby a bug in the programme ipyrad was found out, the importance of paralogs was analysed and the difference between the coding of AFLP and diploidised SNP-Data was worked out

    Felix Rehms (Münster University)

    Felix Rehms's Master thesis was awarded with the Prize for the Best Plant Science Master Thesis, which was carried out at Westfälische Wilhelms-Universität Münster in the year 2019.

    Title:

    Development and application of genetically encoded fluorescent sensors for hypoxia investigation in plants

    Rehms documents the visualization of Ca2+-accumulation in energy-deprived cells and the subsequent calcium signal propagation in Arabidopsis thaliana seedlings during prolonged oxygen restriction. He also started the development of genetically coded fluorescent oxygen sensors for use in-planta.

    With regards to the growing frequency of extreme precipitation and flooding events caused by global climate changes, tolerance to oxygen deprivation (hypoxia; assumedly the most severe plant stress caused by prolonged submergence) is rapidly gaining relevance as a trait in crop breeding, even though, as of yet, the underlying mechanisms are mostly unknown.

    To shed light on the role of second messengers in a plant’s perception and signal transduction of hypoxic conditions or the resulting energy crisis (caused by inhibition of aerobic respiration), genetically encoded fluorescent sensors of cytosolic Ca2+ and ATP concentration were employed for microscopic investigation of submerged Arabidopsis thaliana seedlings in a spatio-temporal resolution.

    This way, he was able to record multiple waves of Ca2+-elevations, which were assumedly triggered by the collapse of energy upkeep and subsequent breakdown of active transport mechanisms that ensured the upkeep of steep ion gradients across membranes. Starting from the first energy depleted tissues or cells this wave spreads outwards and across the full seedling. The dynamics of these waves and comparisons to ATP monitoring in hypoxic seedlings suggests active signal propagation, rather than a universal increase caused exclusively by energy deprivation and passive ion leakage.

    Additionally, this work documented the beginning development of genetically coded fluorescent oxygen indicators. Such oxygen sensors can be ubiquitously expressed in all tissues and can be applied in-vivo to monitor ongoing developments. In contrast to chemical and physical oxygen measurements, this does not cause any additional plant stress. This makes the fluorescent sensors ideal for the investigation of the oxygen dependency of signals in hypoxic plants. On top of that, the sensors’ independence of plant adaption or developmental mechanisms may lead to the identification of hypoxic niches that were not implicated by expression of hypoxia marker genes.

    The DBG awards the two young plant scientists Dr. Aleksandra Sapala (MPI for Plant Breeding Research Cologne, Dr. Richard Smith at Prof. Miltos Tsiantis) and Dr. Jutta Baldauf (Bonn University, Prof. Frank Hochholdinger) with its Best Paper Prize. Sapala has shown why plants have puzzle cells, how this shape emerges and what advantages they provide for the plant. In the journal eLife (DOI: 10.7554/eLife.32794) she also demonstrates that in plants physics play just an important role as biochemistry or genetics. Baldauf described extensive gene expression complementation in maize hybrids driven by evolutionary younger non-syntenic genes in the journal Current Biology (DOI: 10.1016/j.cub.2017.12.027). These SPE genes could be used to identify high-yield plants. Both awardees will receive their certificates next year during the Conference Botanikertagung in Rostock, Germany. The financial endowments were already presented to them.

    The DBG awarded the two scientists Dr. Katja Meyer (Bielefeld University, WG Prof. D. Staiger) and Dr. Max Lauterbach (Mainz University, WG Prof. G. Kadereit, now Australia) with the Best Paper Prize in Plant Sciences 2018. Meyer adapted the iCLIP technique for plants and identified numerous rhythmic transcripts to be directly regulated by the clock-controlled RNA-binding protein AtGRP7. She published the results in the Journal Genome Biology (DOI: 10.1186/s13059-017-1332-x). Lauterbach identified genes putatively encoding novel C4 proteins through a comparison of five chenopod species with different photosynthetic types. He published the results in the journal Frontiers in Plant Science (DOI: 10.3389/fpls.2017.01939). The awardees will receive their certificates next year during the Conference Botanikertagung in Rostock, Germany. The financial endowments were already given to them.

    DBG Honoured best Master Theses

    Bielefeld University awarded certificates for the best Master theses of the year 2017. Among them the prize for the best plant science master thesis of Jan Hendrik Hoerner (third from right). Photo and Copyright: Ch. Weische, Bielefeld University on 6th Dec 2017

    Why an invasive pest slug devoured some lettuces while others remain untouched was one of the topics of the honoured master theses (little hint: it were not the salads themselves). The other young plant scientists elucidated specific functions of N-glycosylated proteins in plants, analysed the effects of inhibited chloroplast's development on genetic expression, tested, which substances of an invasive plant contributed to substantial crop failure. One thesis clarified three algal taxa of Trachelomonas, that were validly described already 100 years ago. For the fourth time the German Society for Plant Sciences (DBG) has awarded outstanding MSc theses. This year they were given to three female and two male biologists from the universities of Bielefeld, Münster, Salzburg, Kiel as well as LMU in Munich. The summaries and images of the outstanding works are now on the website.

C) The sharply pointed and hairy base of E. cicutarium seed facilitates zoochory. D) Upcoiling awn of the ripe and dry E. cicutarium seed. Once on soil, humidity causes the helical shape to unwind and drill the seed with the sharply pointed base ahead into the ground. Graphs: Jan Hendrik Hoerner

    Jan Hendrik Hoerner's Master thesis was awarded with the Prize for the Best Plant Science Master Thesis, which was carried out at Bielefeld University in the year 2017.

    Title of awarded thesis

    "Allelopathic effects of the invasive plant Erodium cicutarium on agricultural crop plants"

    The invasive common stork´s-bill Erodium cicutarium causes yield reduction of various crops in North America. Jan Hendrik Hoerner examined responsible allelochemicals, natural substances produced by the stork´s-bill, which are able to suppress the growth of other plants. He fractionated phenolic compounds with high inhibitory effects, even in minor concentrations.

    The photosynthetic machinery. Linear electron flow (LEF), cyclic electron flow (CEF) and the roles of the transmembrane electrochemical proton gradient. As electron transfer is coupled to proton translocation, LEF and CEF contribute to the formation of the proton gradient. LEF involves water splitting and NADPH production. The proton gradient fuels ATP synthesis, induces non-photochemical quenching (qE) and exerts photosynthetic control. LHC = light harvesting complex; PS = photosystem; Cyt b6f = cytochrome b6f complex; PC = plastocyanin; FDX = ferredoxin; FNR = FDX:NADP+ reductase; ATPase = CF1-F0-ATP-synthase; PGRL1 = PGR5-like photosynthetic phenotype 1; PGR5 = proton gradient regulation 5.
