Vortragende*r: Dr. Tsu-Wei Chen (Uni Hannover)

Thema: Understanding the dynamics of canopy function in vegetable crops

Datum und Uhrzeit: 29.09.2020 – 13:00 Uhr

Sprache: Englisch

Zusammenfassung: 

Kenntnisse über die dynamische Funktion und die physiologischen Mechanismen auf der Ebene der Überdachung sind erforderlich, um Strategien zur Verbesserung der Leistung von Gemüsepflanzen zu entwickeln. In diesem Vortrag werde ich Gurken und Tomaten, die wichtigsten Gewächshausgemüsepflanzen, verwenden, um zu zeigen, wie sich Salzgehaltstress auf die architektonischen und physiologischen Einschränkungen der Trockenmassenproduktion auf der Ebene der Überdachung auswirkt.

Um dies zu erreichen, werden zwei Rahmenbedingungen für funktionell-strukturelle Pflanzenmodelle ( FSPM), in dem die 3D-Architektur von Pflanzen explizit beschrieben wird, wurden konstruiert, parametrisiert und bewertet. Das erste Gerüst war ein statisches Architekturmodell des Gurkenhimmels in Verbindung mit einem biochemischen Modell der Photosynthese und einer quantitativen Begrenzungsanalyse der Photosynthese, um die Auswirkungen physiologischer Prozesse auf die Begrenzung der Photosynthese vom Blatt auf die gesamte Pflanzenebene zu skalieren. Unter Verwendung dieses Rahmens wurden die Einflüsse des Salzgehalts, der augenblicklichen Lichtverhältnisse und ihrer Wechselwirkungen auf architektonische und physiologische Einschränkungen bei Gurken systematisch und quantitativ analysiert. Das zweite Gerüst, ein dynamisches FSPM des Tomatenwachstums, wurde verwendet, um die Auswirkungen architektonischer Merkmale auf die Trockenmassenproduktion der gesamten Pflanze und ihre Wechselwirkungen mit Temperatur und Salzgehalt zu untersuchen. Wir unterstreichen die Bedeutung der Pflanzenarchitektur auf Baldachinebene für die Untersuchung der Reaktionen der Pflanzen auf die Umwelt und zeigen die Vorzüge von FSPM als heuristisches Werkzeug.

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.

Dr. Vanessa Wahl

Max-Planck Institut für Molekulare Pflanzenphysiologie, 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).

„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.
