Invitation to the guest talk, 05 November 2019

Venue: Conference room

Time: 1 p.m.

Speaker and title of the presentation: Prof. Marc Wolfram & Dr. Martina Artman

Leibniz Institute of Ecological Urban and Regional Development (IOER), Dresden

Spatial sustainability science: The IOER research agenda and its intersections with horticulture research

Abstract:

The Leibniz Institute of Ecological Urban and Regional Development (IOER) in Dresden investigates dynamic interactions between society, ecosystems and built environs at and across multiple spatial scales, as well as options and methods for responsible stewardship towards sustainability. The research is highly interdisciplinary, working across a range of disciplines in the social-, natural- and engineering sciences. It is also transdisciplinary, collaborating closely with stakeholders in the public, private and civil society sectors in knowledge co-production and -transfer. The IOER specifically aims to foster just urban and regional transformations that enable humanity to thrive within a safe ecological operating space. This agenda also entails diverse implications regarding the current and potential future role of horticulture research, considering for instance local food production, environmental quality and conditions, the circular economy, or human-nature relations more generally. Therefore, this presentation will provide a brief introduction and overview of the IOER and its research, focusing specifically on options and opportunities for collaboration with the IGZ.

“Monitoring Cellular Energy Physiology and Regulation in Plants”

 

Abstract

The energy conversion that occurs in plant cells requires tight surveillance and dynamic adjustment to meet demands, maintain efficiency and avoid dysfunction. Frequent and often dramatic changes in the environment and developmental transitions of plants, such as the day-night transitions, changes in oxygen availability or seed germination make tailored control mechanisms particularly important. Nevertheless there is a limited understanding of the dynamics of energy physiology and their regulation at the subcellular level in plants. We have been using quantitative confocal microscopy and fluorimetry to assess transitions in energy physiology in vivo using genetically-encoded fluorescent protein sensors. In this seminar I would like to highlight recent progress that we have made in dissecting subcellular ATP dynamics, redox regulation and calcium transport. The impact of cellular energy dynamics and its control as central determinant of plant-environment interactions will be discussed.

On Tuesday, 21 May 2019, scientists from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrttechnik; DLR) and its Institute for Aerospace Medicine of, the Helmholtz Centre for Environmental Research (UFZ) in Leipzig, the German Biomass Research Centre (DBFZ) in Leipzig and the Erfurt University of Applied Sciences met with staff from the program areas “Functional Plant Biology” (PB FUNCT), “Plant Quality and Food Safety” (PB QUALITY) and “Horticultural Systems of the Future” (PB HORTSYS) as well as the Scientific Director of the IGZ met for an expert discussion at our institute.

The aim of this meeting was to create a inter-institutional and interdisciplinary professional exchange on approaches and possibilities for the desalination of urine-based recycling fertilizers.

Background: Both urine and urine-based recycling fertilizers, such as C.R.O.P. or Aurin fertilizers, have a very high salt content (especially NaCl), which can be a problem in horticultural applications (i.e. salt stress for the plants). Possibilities to reduce the salt content include on the one hand process-technical approaches during the production of the recycling fertilizers, and on the other hand a cascade effect in which first salt-tolerant plants (so-called halophytes) and then vegetables are cultivated.

The participants exchanged information on preliminary work, experience and knowledge of their field and discussed relevant and interesting research questions. This meeting offered scientists from different fields the opportunity for an enriching and creative exchange of ideas. The interdisciplinary discussion ultimately led to a deeper and at the same time broader understanding of the problem and possible solutions by all participants. In the synthesis of the meeting the concept of a future research cooperation was outlined and thus the foundation stone for an interdisciplinary cooperation of the participating institutes was laid.

On May 6th 2019, Dr. Ariane Krause and Franziska Häfner of the program area “Horticultural Systems of the Future” (HORTSYS) invited to the symposium “Multiple perspectives on circular economies & horticulture: Learning from & about Indian natural farming”. The director of the institute, Prof. Dr. Eckhard George, first welcomed the numerous guests. This was followed by a series of short lectures on the subject. Ariane Krause began with a lecture on ongoing research projects at the IGZ, which aim to increase sustainability in horticultural production systems through nutrient recycling. This was followed by Dr. Mrinalini Kochupillai of the Technical University of Munich who discussed what the EU can learn from the Indian experience regarding their political framework to natural agriculture. Jasper Matthiessen & Karthik Jeganathan of the Arts of Living Foundation spoke about the experiences and the scientific background of the traditional Sri Sri Natural Farming principle in modern Indian agriculture. Julia Köninger of TU Munich spoke about future fertilization strategies in European and Indian agriculture. Dr. Daniel Münster of the University of Heidelberg concluded the round of lectures with insights into his ethnographic work on the Indian agricultural principle of “Zero Budget Natural Farming”. After a tour of the institute, during which the guests were able to gain an insight into the work of IGZ, the participants met in the afternoon to discuss future research questions and possible cooperation with a view to future EU calls. Already in December 2018 scientists from different disciplines met with representatives from practice, industry and ministries for a symposium on “Nutrient Cycling for Circular Economies”. We are pleased about the renewed interest in the dialogue on nutrient recycling, environmental services and horticulture and plan to continue this series of symposia.

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.

How to define nutritional security and how can plant science contribute to increase nutritional security? These are only two of the questions discussed on the first meeting of the newly established European Plant Science Organisation – EPSO Working Group “Nutritional Security” organized by IGZ Leibniz-Institut für Gemüse- und Zierpflanzenbau. Participants from around Europe are meeting in Berlin to figure out how research, economy and politics could contribute to enhancing nutritional values of the food consumed. It is well known that eating fresh fruits and vegetables is incredibly important. But convincing people to consume healthy, diverse food is also a matter of economic circumstances, education, communication and of trained habits.

“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.

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.

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.

Colloquia

Invited guest, 29 October 2019

Venue:

Conference room

Time:

1 p.m.

 

Speaker and title of the presentation:

Dr Vanessa Wahl

Max Planck Institute of Molecular Plant Physiology, Potsdam-Golm

Resource-demanding developmental transitions in Arabidopsis thaliana and Solanum tuberosum

 

Abstract

The research group of Dr Vanessa Wahl focuses on how the metabolic and nutritional status modulates developmental transitions in plants. There is a particular interest in processes happening at the shoot apex that regulate meristem size and the timing of e.g. the floral transition. They use Arabidopsis thaliana as a model system in order to understand the basic mechanisms, but are extending the knowledge gained to study the regulation of developmental transitions in the crop species Solanum tuberosum (potato) and the ornamental species Chrysanthemum. Dr Vanessa Wahl will present recent findings on how the availability of sucrose or nitrate affect plant development (e.g. Musialak-Lange et al., in prep.; Olas et al., New Phytologist, 2019).
