Job TitlePostdoctoral Researcher
Closing Date8 Feb 2018
GradeSC6
Starting Salary£31,250 - £38,100
Hours per week 37
Project Title Immunity By Pair Design
Expected/Ideal Start Date 01 Mar 2018
Months Duration 30
Main purpose of the job Postdoctoral Researchers work with limited supervision to carry out individual and collaborative research projects relevant to the overall needs of the research programme.



This project will (1) reveal design principles of paired immune receptor complexes and (2) elevate plant disease resistance by enabling design of immune receptors with new recognition capacities.



Plant immunity is triggered upon pathogen detection by dedicated immune receptors. Like animal Nucleotide-binding Leucine-rich Repeat (NLR) proteins, plant immune receptors have a modular structure and can work in pairs, both of which are required for defence activation upon recognition of specific pathogen proteins. How such intracellular immune receptor complexes activate defence solely upon recognition of microbial molecules is poorly understood.



Using novel methods such as domain/domain cross-linking with mass spectrometry (XL-MS) and cryo-electron microscopy, as well as X-ray crystallography, Biochemistry, genetics and cell biology, we will define at a structural level the domain/domain interactions within an immune receptor complex, and how these change upon pathogen perception. The Arabidopsis RRS1/RPS4 immune receptor acts to detect pathogen effectors that target WRKY transcription factors, converting effector interactions with the RRS1 WRKY domain into defence activation via RPS4. We will reveal the intra-molecular reconfigurations required for signalling and thus tackle a problem of broad significance, both for immune receptors, and for other intracellular receptors that are activated by ligand-dependent release from negative regulation.
Department Biological Chemistry
The Biological Chemistry Department at the John Innes Centre carries out fundamental research on molecular processes in plants and microbes. With activities ranging from determining DNA topoisomerase structure to mechanism and the generation of novel functional nanostructures from engineered viruses, we employ a multidisciplinary approach that embraces contemporary aspects of enzymology, structural and molecular biology, bionanotechnology, carbohydrate and natural product chemistry. Coupled with state-of-the-art platform technologies for structural, proteomic and chemical genomic analysis, the Department bridges the gap between molecular science and cellular and systems biology. Collectively these studies provide key information with which to manipulate and control molecules, pathways and processes of agronomic, environmental and industrial importance.
Group Details The Banfield Lab investigates the molecular and structural basis of plant-microbe interactions. Specifically, we are interested in (i) the structure and function of host translocated pathogen effector proteins, how they interact with host cell molecules to perturb activity for the benefit of the pathogen, and (ii) the structure and function of intracellular plant immune receptors (NLRs). For the latter, we are interested in understanding how they recognise and respond to pathogen effectors and/or their functions.
Advert Text Applications are invited for a Postdoctoral Researcher with skills in structural biology and protein chemistry to join the Laboratory of Professor Mark Banfield at the John Innes Centre, in collaboration with Prof. Jonathan Jones' lab at the Sainsbury Laboratory (TSL), in a team to investigate mechanisms of plant innate immunity in the ERC-funded project "ImmunityByPairDesign" (https://tinyurl.com/y8fetp57).

Background:

The project addresses the design principles of paired intracellular plant immune receptor complexes. Plant immunity is triggered upon pathogen detection by dedicated immune receptors. Nucleotide-binding Leucine-rich Repeat (NLR) proteins survey the host intracellular environment and activate defence upon detection of pathogen molecules. Some plant NLRs work in pairs, with one partner acting as a “sensor” to detect pathogens, and the other as a “helper” required for initiation of immunity. Some sensor NLRs contain integrated domains that act as baits to target pathogen molecules by direct binding, or act as substrates of pathogen-derived enzymes. This project aims to unravel how the Arabidopsis RPS4/RRS1 NLR pair converts AvrRps4 or PopP2 recognition into defence activation. We are defining the intra- and inter-molecular interactions of RPS4 and RRS1 in both pre- and post-activation states, revealing the reconfigurations required for signalling. We also aim to use this information to design new specificities for plant NLRs that may have utility in crop disease control.

The role:

This position would suit researchers interested in the molecular mechanisms that underpin innate immunity signalling in plants and animals, with a strong focus on in vitro biochemistry and structural biology. The post-holder will work under the guidance of Prof. Banfield but will be expected to show initiative within the context of the project, in collaboration with RPS4/RRS1 team members in the Jones group. Our goal is to understand the properties and roles of the domains of RPS4 and RRS1, and in particular, to define the structure of these domains, and the structural basis for their interactions pre- and post activation.


The ideal candidate:

The John Innes Centre is a world-class research institute and is looking to appoint an exceptional candidate who has, or expects to soon receive, a PhD in the areas of biochemistry, molecular biology, structural biology, or a related subject. The post-holder will have opportunities to develop their technical and transferable skills during the duration of the appointment through training programmes, coaching and mentoring.

The post-holder will have a keen enthusiasm for research and have long-term career aspirations in science. As well as the ability to carry out independent work they must also be a strong team player and have excellent communication skills. The successful candidate will join a multidisciplinary group with wide interests in molecular plant pathology.

Additional information:

Salary on appointment will be within the range £31,250 to £38,100 per annum depending on qualifications and experience. This post is for a contract of 30 months, with the possibility of extension.
