Impact Summary

Plant -microbe interactions in the rhizosphere can have major impacts on crop yields, with pathogens generating global losses of billions of pound annually. In this project we provide fundamental new understanding about the factors which control the assembly of rhizosphere communities, and will use cutting edge next generation sequencing (NGS) methods to unravel the mechanisms by which plants affect, and are affected by, microbial communities. Importantly, we will use oilseed rape (OSR) as the model system for our research since it suffers from 'yield decline' arising from the development of a detrimental microbiome, which causes UK losses of £43-86 million/year. Our research will impact the following groups: (1) The academic community, particularly those with interests in agricultural systems biology, plant-soil interactions, plant pathology and environmental microbiology. Researchers will particularly benefit from our use of NGS approaches to unravel plant-microbe-soil interactions, and from engineering the rhizosphere biota for beneficial functions. We will engage with researchers through journal papers and at key scientific conferences. The sequencing experiments are a valuable experimental resource for workers in related fields. We will open this data to other researchers for complimentary work, providing added value to the experiments. (2) The agricultural industry, particularly stakeholders with an interest in promoting productivity and sustainability, including crop breeders, land managers and farmers. Industry will benefit from new scientific knowledge which will provide novel approaches to manage the rhizosphere: (a) we will identify microbial contributors to yield at the landscape scale, including, potentially, new pathogens, and soil and environmental characteristics which relate to pathogen distribution. This will underpin development of new crop protection strategies (eg via pesticides) (b) we will identify co-exclusion and co-occurrence relationships within the microbiome which could facilitate development of novel biocontrol approaches (c) we will identify changes in microbial function, and associated plant responses as it changes from a healthy to unhealthy state. This could lead to targeted gene and physiology based crop improvement strategies (d) we will provide soil management options to mitigate development of yield decline; this will provide tangible outputs to farmers within the project timeframe (e) we will elucidate the potential for rhizosphere microbiome engineering through crop genotype which could lead to rotational strategies, and breeding approaches, to manipulate the rhizosphere. While providing outputs to the OSR industry (see letters of support from United Oilseeds and Elsoms) the principles of the work, and the tools we will develop, will be relevant to stakeholders across the industry (see letters of support from Agrii and Origin Fertilisers). (3) Government (eg Defra) and industry organisations (eg NFU, HGCA) with a role in supporting and promoting the competitiveness of UK agriculture; in particular the research addresses the priorities of HGCA (see letter of support). We will form a project steering group with industrial and government stakeholders which will advise on technology transfer. We will engage with these stakeholders through workshops at Warwick in months 24 and 42, project newsletters and the project website, which will provide a summary of project progress. We also intend to engage strongly with the public. In addition to press releases, production of a video iCast and a project website, we plan a series of events at the Natural History Museum, London, where science derived from the project will be communicated directly to the public, including schoolchildren. Society will benefit from trained researchers adept at multidisciplinary working, with skills in ecology, agricultural science and microbiology, and cutting edge NGS methods.
