Improving wheat photosynthesis through wide crossing with wild relatives and selection using novel environments

Lead Research Organisation: University of Nottingham
Department Name: Sch of Biosciences

Abstract

Wheat yield gains are currently insufficient to meet the demands of the future thus posing a risk to global food security. In order to increase yields it is necessary to improve photosynthesis, as this is the primary determinant of biomass. The ability to select for improved photosynthesis within modern bread wheat cultivars is constrained by genetic 'bottlenecks' which occurred following domestication. To increase genetic diversity it may be possible to exploit wild relative germplasm, of particular interest are the genus' Aegilops and Triticum, which exhibit variable photosynthetic traits. In this work, double haploid lines of bread wheat containing introgressions from Aegilops mutica and Triticum urartu are to be screened using a variety of novel environmental conditions including sub-ambient CO2 . The photosynthetic , photoprotective and photorespiratory properties will be evaluated using a variety of techniques including chlorophyll fluorescence, gas exchanging and leaf biochemistry.

Description This is an ICase studentship with the industrial partner BASF. A three month placement will be completed in 2021 in Ghent, Belgium. 
Organisation BASF
Country Germany 
Sector Private 
PI Contribution A placement will be completed in 2021 at BASF in Ghent, Belgium.
Collaborator Contribution The partners have provided financial support for this project, which has contributed to the cost of growing space and resources required to complete experimental work at the University of Nottingham. During a planned three month placement at BASF in 2021, accommodation and research facilities will be provided and paid for by BASF. Throughout the project experimental design , ideas and data analysis have been discussed in meetings with two supervisors at BASF, to come to an agreement on the progression of the project.
Impact Outcomes not available at this point.
Start Year 2017

Results and Impact Accepted onto the learning leader program for 2020 which runs between The Univeristy of Nottingham and local primary schools. I will be running five sessions in June 2020, which will cover the following topics: The importance of wheat, Role of photosynthesis, How do plants take up water and use light energy, The hidden parts of a leaf - an introduction to stomata.
