PhD Studentship - Understanding the soil microbiome under controlled light conditions

Our research group is working within a consortium that is testing semi-transparent solar installations on crop growth-houses, to enhance biological and financial resilience in protected farming. We are evaluating electricity supply, the effect of partial shade on crops, and use of resources, such as water-use efficiency. As well as commercial aims, there is scientific interest in how manipulating the light quantity and quality can alter or enhance crop characteristics. Typically, LED-lighting is tailored by the farmer, but coloured, semi-transparent, photovoltaic materials can also be used to shade crops in all or part of the light spectrum. This project will provide new cell biology and commercial understanding of crop effects, and explore how altered light regimes affect pathogens, rhizosphere communities and plant root biology. The ideal candidate would have experience in microbiology, plant biology or molecular biology. You should be enthusiastic about supporting NetZero farming and have an interest in the fundamental science that underpins agriculture. Experience in analysing microbiomes and bioinformatic data would be helpful but training will be provided in all required areas. 

Project design: 

1. Microbiome and mycorrhizae in altered light conditions

              Rhizosphere microbe number and diversity will be surveyed to inform experiments on plant-microbe communication (ii) and protective organisms (iii)

2. Host-plant root signals under altered light conditions

              Plant metabolites and their specific transport will be studied in rhizosphere and root cells to understand effects of light quantity/quality on microbial behaviour and crop 

3.  Disease characteristics under altered light 

              Identification and pathogenicity testing of representative soil-borne pathogens will be linked with soil microbial health (i)

Support and training:

The doctoral student will be supported by a team with expertise in plant biology, soil health, next generation sequencing and statistics and they will work within two research groups of scientists at all education and career stages. The student will join the large community of postgraduate students across Science, NRI and the Faculty. Training and courses will be provided and project components tailored to meet the interests and experience of the applicant. There will be opportunities for networking with farm businesses and dissemination of findings at conferences.
