Nottingham PhD studentship: Root sealing regulatory mechanisms in plant colonised by microbes
To seal or not to seal. Characterization of root sealing regulatory mechanisms in plant colonised by microbe
Plant roots are responsible for nutrient and water uptake from the “outside” environment; the soil. This process is controlled by a specialized cell layer in the root, the endodermis. To keep the right concentration of nutrients in the plant, avoiding its leakage, this cell layer has evolved mechanisms of sealing, the blockage of the space between contiguous cells. One missing aspect in this sealing mechanism, critical for the organism survival, is the resident microbiota that is metabolically active and might disturb the cell layer sealing with consequences for nutrient and water balance.
With this proposed project, the University of Nottingham will explore a new technological concept around the use of exogenous small molecules that mimic plant regulatory components to control the root sealing mechanisms directly or through their interactions with the resident root microbiome. It represents an invaluable tool to gain new insight into the regulation of new mineral nutrient homeostatic mechanisms controlled by the root microbiota. Questions Nottingham will address include: What regulatory molecules coordinate the crosstalk between the root sealing and the microbiota? How do different regulatory elements control mineral nutrient accumulation under ecological relevant conditions?
The project will be supervised by a team of supervisors that includes Dr Claudio Screpanti from Syngenta and Dr Gabriel Castrillo and Dr Almudena Ortiz-Urquiza from the University of Nottingham. The successful candidate will join the University of Nottingham’s Plant-Microbe interactions and nutrition group at Sutton Bonington campus, Plant Sciences building at the University of Nottingham.
The successful candidate will have access to a unique range of advanced analytical techniques and equipment (ICP-MS, Laser Ablation Tomography, micro-computed Tomography) and world-class facilities with international standards. They will receive structured training programmes at the University of Nottingham and Syngenta, and attend various training courses (e.g., IT, Career, Research Methods, Project Management) to develop their research and transferable skills.
This PhD is supported by Syngenta Group that is a leading technology company for sustainable agricultural innovation. Syngenta’s mission is to offer large and small farming businesses the tools to address a wide range of challenges associated with crop productivity and health, to manage the effects of climate change and to help preserve biodiversity. The student will have the opportunities to visit and interact with different teams in the R&D environment at Syngenta. The PhD student will be introduced to the current paradigm to discover and optimize new agrochemicals, the so-called Design-Synthesis-Testing-Analysis (DSTA) cycles. Ad-hoc interactive sessions will be organized with different specialists (i.e. chemists, biology, computational experts) at the Syngenta labs. The PhD student will have the opportunity to present her/his projects to the Syngenta scientific community.
The application deadline is Thursday 30 June 2022.
