The future lies in our hands – today, on Future Day 2019 (Zukunftstag 2019), we took the opportunity to show young people relevant future research topics and interesting jobs related to plant science.

Eight girls and boys visited the IGZ for a one-day internship and were thrilled. They made soap, infiltrated tobacco plants, spread yeast cultures on plates and tried out our microscopes. In the greenhouse, they were learned how to adjust the pH-value of nutrient solutions and had a look into climatic chambers and under the greenhouse. Overall, a diverse program under competent and friendly guidance by our staff for and with smart, interested children and young people.

We all had a very nice day and maybe we could give an impulse for later career decisions!

We congratulate our colleague Ariane Krause on the successful publication of her dissertation at the Technical University of Berlin with the title:

“Valuing wastes – an integrated system analysis of bioenergy, ecological sanitation, and soil fertility management in smallholder farming in Karagwe, Tanzania”

Abstract:

My dissertation had as its starting point the intention of two Tanzanian farmer’s initiatives and their German partners to disseminate sustainable cooking and sanitation technologies to smallholder households in Karagwe District, in northwest Tanzania (TZ). These locally developed and adapted technologies include improved cook stoves, such as microgasifiers, and a system combining biogas digesters and burners for cooking, as well as urine-diverting dry toilets and thermal sterilization/pasteurization for ecological sanitation (EcoSan). Currently, the most common combination of technologies used for cooking and sanitation in Karagwe smallholdings is a three-stone fire and pit latrine. Switching to the new alternatives could potentially lead to (i) optimized resource consumption, (ii) lower environmental emissions, and (iii) a higher availability of domestic residues for soil fertility management. The latter include biogas slurry from anaerobic digestion, powdery biochar from microgasifiers, and sanitized human excreta from EcoSan facilities. These residues are `locally available resources’ that can be used for on-farm material cycling. Using TZ as an example and local initiatives as case studies, I have examined the triple nexus of `energy-sanitation-agriculture’ with an interdispicplinary multi-method approach.

Empirically and analytically, my results shed light on agronomic potentials of an intersectional resource management for circular economies and on values of material cycling in smallholder farming systems as well as on weak points in the system, from both ecological and socio-economic perspectives. As one example, I demonstrated that all the treatments analyzed could enhance crop productivity up to 400 % in a short-term experiment on the local Andosol. [Please see longer Abstract in my thesis for the summary of more results.]

Ultimately, I conclude that a particularly promising way of implementing an intersectional resource management around the nexus energy-sanitation-agriculture is the combination of using microgasifiers for cooking and implementing EcoSan, in addition to the combined recycling of biochar and sanitized excreta in `CaSa-compost’. This approach can achieve multiple goals including: (i) increase access to fertilizers, (ii) decrease nutrient depletion and acidification of soils, (iii) increase food production and farm income, (iv) reduce resource consumption, and (v) reduce environmental impacts, like global warming or eutrophication. For many smallholder farmers in Sub-Saharan Africa, this practical approach thus represents a viable exit strategy from the vicious circle of soil acidity and P-scarcity leading to insufficient production of food crops, which in turn leads to insufficient production of residual matter for soil fertility management and improvement.

There are many research institutes focussing on environmental sciences and earth sciences belonging to the Leibniz association or Helmholtz association. All of them working on exciting topics highly relevant to science, politics, the public or industry. Being in contact with these stakeholders, starting a dialogue and involving them into projects has always been important, but it is getting even more important during the last years.

This monday, december 3rd the Workshop “Wissenstransfer in den Umwelt- und Geowissenschaften bei Leibniz und Helmholtz” (`Knowledge transfer in environmental sciences and earth sciences´) took place in Berlin, supported by both associations. The workshop aimed to build networks between colleagues responsible for transfer in both associations, to find common topics and  identify challenges to work on. Discussions mainly focussed on culture of transfer at the institutions, stakeholder engagement, indicators of knowledge transfer and the development of competences in this field.

The event was initiated and organized by transfer managers from:

  • Leibniz-Institute of Freshwater Ecology and Inland Fisheries (Johannes Graupner, IGB),
  • Earth System Knowledge Platform of the Helmholtz association (Nicola Isensahl, former ESKP),
  • Leibniz Institute of Vegetable and Ornamental Crops (Marina Korn, IGZ),
  • Alfred-Wegner-Institute (Gesche Krause, AWI Helmholtz),
  • Leibniz Center for Agricultural Landscape Research (Katharina Schmidt, ZALF & agrathaer)
  • and Potsdam Institute for Climate Impact Research (Ulrike Sylla, PIK Leibniz).

During a final feedback round both, the idea and results of the workshop have been estimated very positively by the participants.

“Epigenetic control of gene activation in Arabidopsis flower development”

 

Abstract:

Developmental switches and cell fate decisions in plants require coordinated changes in the activities of thousands of genes. Concerted activities of transcription factors and epigenetic regulators are essential for spatiotemporal control of gene expression programs. Polycomb repressive complex 2 (PRC2) mediates the epigenetic memory of gene silencing in plant development, thereby restricting gene activities to specific cell types and developmental stages. RELATIVE OF EARLY FLOWERING 6 (REF6) is a Jumonji (JMJ)-type histone demethylase that counteracts PRC2-mediated gene silencing in plants. Research in my group recently showed that REF6 and its two close paralogs determine spatial ‘boundaries’ of the repressive histone H3K27me3 mark in the genome, and control the tissue-specific release from PRC2-mediated gene repression. Targeted mutagenesis revealed that these histone demethylases display pleiotropic, redundant functions in plant development, several of which depend on trans factor-mediated recruitment. Thus, JMJ-type histone demethylases restrict repressive chromatin domains, and contribute to tissue-specific gene activation via complementary targeting mechanisms.

Metabolic differences in chromosome substitution lines of Arabidopsis thaliana received by Reverse Breeding”

 

Abstract:

Traditionally, hybrid seeds are produced by crossing selected inbred lines. A recent method for haploid production in the model plant A. thaliana (Ravi and Chan, 2010) enabled us to provide a proof of concept for an alternative strategy: Reverse Breeding, a new approach that simplifies meiosis such that homozygous parental lines can be gene-rated from a vigorous hybrid individual (Dirks et al. 2003, 2009). We silenced DMC1, which encodes the meiotic recombination protein DISRUPTED MEIOTIC cDNA1, in hybrids of A. thaliana, so that non-recombined parental chromosomes segregate during meiosis (Wijnker et al. 2008, 2012). We then converted the resulting gametes into adult haploid plants, and subsequently into homozygous diploids, so that each contained half the genome of the original hybrid. From 36 homozygous lines, we were able to identify a complete set of chromosome-substitution lines. Some of those lines were analyzed for metabolic differences by LC-MS.  Among others, several glucosinolates have already been identified to decrease in one of the chromosome substitution lines. Elucidating the genetic differences between the parental lines can explain those metabolic changes.

„Fungal root endophytes and their potential role for improving agriculture under nutrient and drought stress”

 

Abstract:

All terrestrial plants in natural ecosystems are assumed to have a symbiotic relationship with fungi, with particular importance attached to fungal root endophytes. This highly diverse group of fungi can have a profound impact on plant communities and their fitness by initiating tolerances against abiotic and biotic stressors. The aim of the project is to characterize selected fungal root endophytes from plants of disturbed sites (reclamation sites) or extreme habitats to characterize these fungi and to investigate their effect on the growth of agricultural plants under nutrient and drought stress.

In the scope of the research project “VUNA” they developed the new VUNA-recycling process. During the process they obtain nutrients out of urine and produce an urine-based fertilizer. The final product is called Aurin and has got a global approval.

Philip A. Wigge was appointed W3 Professor for Plant Nutritional Genomics at the Institute of Biology and Biochemistry at the University of Potsdam, as a joint professorship with the Leibniz-Institute of Vegetable and Ornamental Crops (IGZ).

After studying Biochemistry at the University of Oxford, Philip Wigge obtained his PhD from the University of Cambridge studying how yeast cells divide. During his postdoctoral studies he switched his research focus to plants, working at the Salk Institute and later at the Max-Planck-Institute for Developmental Biology in Tübingen. During this time he participated in the discovery of the compound that induces flowering in plants (florigen). Since 2005, Philip Wigge has been an independent group leader, first at the John Innes Centre in Norwich and since 2012 in Cambridge at the Sainsbury Laboratory. His research seeks to understand how plants sense and respond to temperature. Plants are remarkably responsive to temperature, and detect as little as a 1ºC difference in temperature. This is particularly relevant in the context of climate-change, where crop yields have already been adversely affected by heat stress. Philip Wigge will be a Head of Department at the IGZ and is particularly interested to develop wide-ranging collaborations within the Berlin/Brandenburg area to accelerate the development of climate-resilient agriculture.

IGZ und many of its cooperation partners are looking forward to work with Philip Wigge and his group. His work is of fundamental scientific interest, but also has a large potential value for food production systems in a changing environment. Philip is now transferring from Cambridge to Grossbeeren/Potsdam and will have his lab established at IGZ in spring of 2019.

Space Medicine meets Horticulture

When thinking about medicine (and space), horticulture won´t be your next thought necessarily. But why not? Not only that  healthy human nutrition  definitely includes vegetables;  research in horticulture uses  state-of-the-art lab equipment, phytochambers and hightech-greenhouses to investigate plant genes  and  metabolites, plant growth and growth conditions, as well as the  benefits of plants for people.

Not only that  healthy human nutrition  definitely includes vegetables;  research in horticulture uses  state-of-the-art lab equipment, phytochambers and hightech-greenhouses to investigate plant genes  and  metabolites, plant growth and growth conditions, as well as the  benefits of plants for people.

Monday this week Prof Hanns-Christian Gunga and Dr Oliver Opatz  from the   Center for Space Medicine and Extreme Environments  of the  Charité Berlin visited the IGZ. They were particularly interested in our state of the art technical infrastructures such as the gas exchange greenhouse and the climate chambers for investigating the impact of extreme environments (e.g. temperature) on the human body.

Prof Tilman  Brück, head of the Research Group Economic development and Food security, Prof Susanne Baldermann, head of RG Food Chemistry and Human Nutrition, and Dr Hanna Freudenreich explained the research  topics and methods of our institute. While showing Prof Gunga and Dr Opatz around, a lively discussion ensued on shared knowledge gaps, common methods and potential new bridges between  both  scientific fields – horticulture and (space) medicine.

An International, Interdisciplinary Research Workshop

With financial support from BMBF and the Leibniz Association

 

2-3 April 2019

Bonn, Germany

 

Organizers: Tilman Brück (IGZ and ISDC), Heinz Peters (Welthungerhilfe) and Martin Petrick (Justus-Liebig-Universität Gießen and IAMO)

The objective of the workshop is to advance our knowledge of home and school gardens, resilience, food security, and related interventions. We would like to deepen our understanding of how informal small-scale home gardening acts as a coping strategy to strengthen the food and nutritional security and resilience of vulnerable households living under extreme uncertainty. In addition, we would like to learn more about how home and school gardens may have positive effects beyond their immediate outcomes (food security and nutrition), such as on women empowerment.

 

Please go to the following website for further information on the application and registration for the workshop: www.igzev.de/crises_workshop

Also this year IGZ is – of course – participating in the Zukunftstag (Future Day) – Boy´s- and Girl´s Day, since we would like to give you the chance to get an insight into the fascination of plant sciences.

The day starts on March 28th at 9.30 am and we´ll be done around 2pm.

 

And that´s what we offer to the girls and boys:

  • conduct experiments in our labs
  • prepare and check experiments running in the greenhouses
  • get a tour through the Gas Exchange Greenhouse (unique in Germany) and our phytochambers

 

We are looking forward to the girls and boys visiting us on March 28th.

Unfortunately we are booked out already, but there will be another chance next year!

 

And here are some memories from last year (2018):
