* APPLY VIA: https://research.reading.ac.uk/foodbiosystems/apply-for-a-phd/ * * DO NOT APPLY DIRECTLY TO QUEEN'S FOR THIS PHD PROJECT * Plants manipulate the rhizosphere (soil surrounding the plant root) through the release of water-soluble and volatile organic compounds known collectively as root exudate. Root exudate can recruit beneficial soil microflora and fauna; however, it can also attract parasites and pathogens, with implications for plant health and yield. Our preliminary data demonstrate that temperature alters tomato root exudate composition, which affects the hatching and attraction of economically important plant parasites and microbes. Understanding the impact of temperature on important plant-rhizosphere interactions will help to develop climate-smart approaches to crop protection, driving the sustainable intensification of agriculture. We have generated transcriptomic datasets from developmentally-matched tomato seedlings grown independently at 18, 23 and 28 degrees C. Our data indicate that non-coding microRNAs and predicted target genes are differentially expressed as a factor of temperature. MicroRNAs regulate the expression of target genes in a sequence-dependent manner, modulating diverse aspects of plant physiology and function. Individual microRNAs have the potential to regulate hundreds of transcripts simultaneously. On that basis, microRNAs and/or microRNA target sites on targeted genes, represent an attractive focal point for breeding / biotechnology and novel crop improvement strategies. Our data identify a range of target genes that demonstrate asymmetric differential expression relative to their cognate microRNA, belong to a wide range of families, including ATPBinding Cassette (ABC) transporters, Multidrug And Toxic compound Extrusion (MATE) transporters, Ethylene Response Factors (ERFs), UDP-glycosyltransferases, and sugar transporters, which have all been linked to the control of root exudate composition previously. We hypothesise that these microRNAs and target genes contribute to the modification of root exudate composition and altered interactions with parasites and microbes as a factor of temperature.
The goal of this project is to link selected temperature-regulated microRNAs and target genes to specific changes in root exudate composition, and altered plant-rhizosphere interactions. We will address this goal by confirming microRNA-mRNA interactions (transcriptomics and degradome sequencing) and investigating
microRNA and target gene functions (transgenic over-expression / microRNA decoys / RNA interference). We will
then assess parasite / microbe behaviours for a range of organisms, including Globodera pallida, Meloidogyne
incognita, Bacillus subtilis, Pseudomonas aeruginosa, Agrobacterium tumefaciens, Funneliformis and Rhizophagus species (hatching / attraction / invasion / biofilm formation / Vir gene induction / spore
germination / hyphal branching etc. as appropriate to individual species). We will also assess exudate compositional change using metabolomics (LC-Qtof-MS and GC-MS).
A core driver for this proposal is our recently discovered ability to alter the behaviour of selected plant pathogens and microbes within the rhizosphere by manipulating plant root exudate composition using
temperature. This finding provides a new opportunity to: (i) dissect exudate-pathogen interplay to optimise the selection of beneficial (pathogen inhibiting) exudate components; (ii) identify the mechanisms driving beneficial plant root exudate changes. This project will link individual temperature-regulated microRNAs and target genes to specific changes in root exudate chemistry, and altered plant-rhizosphere interactions. These microRNAs and target genes could be exploited for crop improvement through breeding, genome editing or biotechnology. Likewise, an understanding of the exudate compounds that influence organismal behaviour in the rhizosphere would be valuable, and could lead to new methods of rhizosphere engineering.
Training opportunities: Technical training will include: transcriptomics and bioinformatics; core molecular techniques (including DNA / RNA extraction, qRT-PCR etc.); plasmid design and construction; plant transgenesis;
reverse genetics; parasite and microbe behavioural assays / AMF interaction assays will be taught in conjunction with collaborators in the Pelligrino lab (Scuola Superiore Sant’Anna [SSSA; Pisa, Italy]); metabolomics and data analysis; training in communication with the general public, including children through workshops/school visits.
Attendance at diverse national and international conferences will provide further opportunities to develop presentation skills and network with peers. QUB offers a wide range of training courses in conjunction with the Graduate School, and the ‘Postgraduate
Development Programme’. Likewise, The University of Reading offers the ‘Reading Researcher Development Programme’. Collectively, these programmes offer a broad range of relevant skills and training opportunities for the student.
There will also be opportunities to collaborate with international partners in Kenya / Ghana, to explore opportunities to translate project outcomes into the sub-Saharan Africa context.
Student profile: This project would suit a student with a degree in biological science / microbiology / plant biology, who has a keen interest in plant interactions. The successful student should be willing to learn a wide
variety of technical skills and apply a creative mind-set to this challenging project. Previous experience in plant sciences, molecular biology, bioinformatics, nematology, microbiology would be beneficial, but not strictly required.
This project is part of the FoodBioSystems BBSRC Doctoral Training Partnership (DTP), it will be funded subject to a competition to identify the strongest applicants. Due to restrictions on the funding, this studentship is only open to UK students and EU students who have lived in the UK for the past three years. The FoodBioSystems DTP is a collaboration between the University of Reading, Cranfield University, Queen’s University Belfast, Aberystwyth University, Surrey University and Brunel University London. Our vision is to develop the next generation of highly skilled UK Agri-Food bioscientists with expertise spanning the entire food
value chain. We have over 60 Associate and Affiliate partners. To find out more about us and the training programme we offer all our postgraduate researchers please visit

The School of Biological Sciences provides PhD and MPhil (research degree) programmes in subjects ranging from basic biochemistry, molecular genetics and cancer research, to agricultural science, marine ecology and the economic evaluation of ecosystem services and food retailing. If you have a topic or research question in mind, please use the Find a Supervisor link (see Apply tab) to identify the most appropriate member of staff to support your idea. If not, don't worry, we regularly advertise funded projects and there is no harm in browsing our academic staff profiles for inspiration and then contacting whoever seems best: we are very open to applications from suitably qualified people interested in scientific research. In every case, a PhD or MPhil course provides the means of being part of a cutting edge scientific research team and contributing to genuine new discoveries or the development of new methods for practical use. If you cannot study full time, we offer pro-rata part time research degree programmes as well.
To help orientation, the School is organised into three research theme clusters:
- Ecosystem Biology and Sustainability
- Microbes and Pathogen Biology
- Food Safety and Nutrition
Ecosystem Biology and Sustainability:
In this cluster, you could research biodiversity and ecosystem services for environments ranging from tropical forests to deep oceans, using field techniques and skills such as wildlife tracking, taxonomy, geostatistics, molecular and genetic ecology, foodweb-analysis, microcosm and mesocosm experiments and mathematical/computational methods. Alternatively, you could study the behaviour and temperament of wild, agricultural or domestic animals and their implications for welfare and ability to respond to environmental change. Potential research projects include phylogenetic analysis of rare and newly discovered species, examination of ecological interactions in tropical systems, agricultural soils, or marine communities, using state-of-the-art genetic analysis, surveys using drones or satellite tagging, or experiments in tanks and field plots, including careful and ethical examinations of animal behaviour. Projects range from theoretical analysis of stability in ecosystems, through discovery of new species and mechanisms of interaction, or responses to climate change, to the assessment of EU agri-environment schemes, development of new methods for commercial fisheries management and economic evaluations of conservation measures. Projects very often have an international dimension and include collaboration with other researchers worldwide.
Microbes and Pathogen Biology:
This cluster covers a diverse array of research interests united by an emphasis on molecular approaches applied to both fundamental and applied questions over the range from molecular to ecological systems. These interests include biochemistry, food safety, microbiology and parasite control with applications in human and animal health, nutrition, plant and soil sciences, and agricultural development. We have a long-standing reputation in parasite biology and in applied microbiology (for example in clearing land of contamination) as well as strong contributions to fundamental methods in understanding cancer, developing veterinary vaccines and molecular detectors for toxins and diseases. The common thread is our strong molecular approach using and developing cutting edge genomic, transcriptomic/proteomic methods. Research students in this cluster enjoy a range of strong international links across Europe, Asia, North and South America.
Food Safety and Nutrition:
Research opportunities offered by this cluster span the entire food chain "from farm to fork" with a strong emphasis on food safety and nutrition, public health and food security. In this cluster you would conduct research under the supervision of leading scientists based in the Institute for Global Food Security and benefit from integration with business experts, helping you gain leadership positions nationally and internationally.

School of Biological Sciences
For a PhD you will have a principal and second supervisor who advise your independent studies and will be supported by a wider team from the academic staff - who they are, of course, depends on your project. For further details on any aspect of postgraduate research degrees within the School of Biological Sciences, contact: email@example.com.
A research degree offers students an opportunity to foster their capacity for independent research and critical thought. It also allows students to explore an area of interest and so understand and solve theoretical and practical problems within the field. Undertaking a research degree can enhance a student’s written and oral communication skills and a PhD is almost always a formal requirement for an academic post.
Assessment processes for the Research Degree differ from taught degrees. Students will be expected to present drafts of their work at regular intervals to their supervisor who will provide written and oral feedback; a formal assessment process takes place annually.
This Annual Progress Review requires students to present their work in writing and orally to a panel of academics from within the School. Successful completion of this process will allow students to register for the next academic year.
The final assessment of the doctoral degree is both oral and written. Students will submit their thesis to an internal and external examining team who will review the written thesis before inviting the student to orally defend their work at a Viva Voce.
Supervisors will offer feedback on draft work at regular intervals throughout the period of registration on the degree.
The minimum academic requirement for admission to a research degree programme is normally an Upper Second Class Honours degree from a UK or ROI HE provider, or an equivalent qualification acceptable to the University. Further information can be obtained by contacting the School.
For information on international qualification equivalents, please check the specific information for your country.
Evidence of an IELTS* score of 6.5, with not less than 5.5 in any component, or an equivalent qualification acceptable to the University is required (*taken within the last 2 years).
