About the Project
Hypothesis: eCO2 acts as a stress stimulus that can alter the expression of defence mechanisms.
Preliminary data: experiments run by the supervisors have demonstrated the impact of eCO2 in response to biotic challenge. First, a metabolomics analysis identified that oak seedling metabolism is altered in a stronger way upon infection with powdery mildew and exposure to eCO2. Second, the amount of plant material consumed by leaf miners was found to be significantly reduced in the mature oak trees exposed eCO2. These results point towards an effect of eCO2 in the expression of plant defence mechanisms, and this is what this project will study.
• Effect of eCO2 in resistance. Disease (powdery mildew) and insect pest (leaf miners) incidence (and phenology) will be assessed in seedlings and mature oak trees growing at the FACE facilities. Both supervisors have extensive expertise on image analysis of pests and diseases.
• Expression of priming of defence. This task will assess the metabolomic changes triggered by eCO2 and challenge with pathogens and pests.
• The interplay between pests and pathogens: This component will determine how the timing of infestation, both in terms of tree or leaf development, but also whether insect pest or pathogen takes hold first, influences resistance outcomes.
This project will address whether the changes triggered by eCO2 are altering the expression of priming of defence and consequently their resistance capacity to pests and pathogens.
An annual maintenance grant at current UK Research Councils rates (national minimum doctoral stipend for 2019/20 is £15,009), to be paid in monthly instalments to the Leverhulme Trust Doctoral Scholar by the University.
All studentships will come with a minimum of £3,000 Research Training Support Grant. This can be increased, if there are justified project costs, up to a maximum of £12,000.
Funding is available for UK or EU students only.
