Submergence-tolerance of wheat (Triticum aestivum) - help it cope with future climate changes!
Common Wheat (Triticum aestivum) is along with rice and corn one of the most important crops worldwide. However, recent climate change models indicate that large wheat growing areas will face an increase in unfavourable growing conditions due to changes in temperature and precipitation in the next decades. This will most likely lead to an increased number of flooded wheat fields, especially in Denmark. Since wheat is a terrestrial plant, it does not cope well with water excess, and tons of crops are therefore already lost each year due to flooded fields.
The exact reason for submergence induces yield loss in wheat is however poorly understood. Is it due to low underwater photosynthesis? Or lacking oxygen transport to the roots? Is there a difference in submergence tolerance between various wheat cultivars and in that case why? These are some of the questions you will have the opportunity to work with in this project by measuring underwater photosynthesis in the lab, doing fieldwork on flooded wheat-fields etc. We are currently a group of associate professor, postdoc and PhD-student working on a Villum Fonden grant to assess the submergence tolerance of wheat.
