Lay Summary (German)

Lead
Pflanzenwachstum wird durch kühle Temperaturen limitiert. Der Zusammenhang von Wachstum und Temperatur unterscheidet sich zwischen Arten und Sorten von Pflanzen. Neue bildverarbeitende Methoden zur Analyse von Wachstum werden im Feld und in der Klimakammer verwendet, um ein besseres Verständnis des Zusammenhangs zu erlangen.
Lay summary

Inhalt und Ziel des Forschungsprojektes

Das Erscheinungsbild oder der Phänotyp von Pflanzen kann heute mit Hilfe bildverarbeitender Methoden sehr präzise analysiert werden. Die technischen Möglichkeiten einer weltweit einzigartigen Feld-Phänotypisierungs-Anlage werden in diesem Projekt genutzt, um das Wachstum und andere Parameter mehrerer hundert Weizen- und Soja-Genotypen im Jahres- und teilweise auch im Tagesverlauf zu charakterisieren. Ebenso werden einige ausgewählte Genotypen unter kontrollierten Bedingungen in der Klimakammer analysiert.

Hauptziel des Projektes ist es, die Aussagekraft von Wuchsanalysen zu überprüfen im Hinblick auf ein besseres Verständnis der Pflanzenphysiologie und der Ertragsbildung von relevanten Kulturpflanzen. Analysen des Transkriptoms und der Genetik der untersuchten Populationen werden im Kontext der pflanzlichen Kühletoleranz diskutiert. Die Untersuchungen werden dazu beitragen, die Leistungsfähigkeit von Kulturpflanzen präziser charakterisieren zu können.

Wissenschaftlicher und gesellschaftlicher Kontext des Forschungsprojekts

Das Projekt verbindet Grundlagenforschung mit anwendungsorientierter Forschung. Weizen und Soja wurden einerseits aufgrund ihrer hohen wirtschaftlichen Bedeutung ausgewählt; andererseits weil sie sich hinsichtlich ihrer Kühletoleranz stark voneinander unterscheiden. Ein verbessertes Verständnis der Kühletoleranz, das mit Hilfe von Wachstumsanalysen erzielt wird, kann den Weg weisen für eine Reihe ähnlicher Anwendungen moderner Phänotypisierungsanlagen zur Züchtung resourceneffizienterer Kulturpflanzen.

Abstract

Plant growth is limited by cold temperatures. The low temperature limit differs between species and it restricts the region in which a crop can be grown. In the field, limiting cold temperatures are often only reached during a short period of the diel (24 h) cycle. It is unknown whether plants have different temperature requirements at different times throughout the diel cycle and also whether and how the genotype-specific temperature requirements change with development. Especially for crop plants, this is an important research area, which needs attention for improved crop performance under cold conditions. This would result in accelerated yield formation, thus minimizing losses conferred by summer drought and heat stress. The applicant’s group has established field phenotyping methods that allow for growth monitoring with high precision at low temperature. The aim of the proposed project is to assess the value of growth monitoring as a dynamic trait in limiting temperatures for physiological and breeding-related studies in winter wheat and soybean. These two species are globally important crops; they differ with respect to their low temperature sensitivity and their growth morphology. Based on field and climate chamber experiments, genome wide association studies (GWAS), analyses of the transcriptome as well as growth modelling will be performed to verify the use of growth response to cold temperatures as a dynamic trait for the evaluation of crop performance. The ETH field phenotyping platform (FIP) will be employed for analyses of growth along with hyperspectral and thermal imaging of a high number of genotypes. The proposed study will contribute to an improved understanding of cold tolerance in crops as well as to improved high-throughput field phenotyping concepts.
