New evolutionary mechanism in fungicide resistance

Analysis of samples from a 160-year-old experiment at Rothamsted Research reveals the re-emergence of an ancient gene due to modern agricultural practices.

Pests and diseases can develop resistance to chemicals used for crop protection, and this poses a major challenge for future food security. The phenomenon of resistance is not unique to agriculture – the issue of drug resistance by microbiotic organisms poses serious challenges for human health also.

  • Quantifying the impacts of the neonicotinoid restriction on oilseed rape pest control, pollination and productivity

    The recent EU restriction on the use of neonicotinoids for oilseed rape (OSR) production has resulted in much speculation, but little evidence, on the impacts the ban has on pest control and crop production. Farmers report crops lost to cabbage stem flea beetle damage, and a move towards foliar-applied pyrethroid insecticides.  This studentship will use a replicated field experiment to compare pest damage and production under 6 treatments: no pest control; neonicotinoid seed dressing; pyrethroid spray(s); acetamiprid spray(s); trap cropping; and undersowing with legumes.

  • Characterisation of Chemical Signalling from Beneficial Trichoderma spp.

    Trichoderma species are ubiquitous soil saprotrophs utilized in agriculture for their biocontrol activities. Some strains additionally possess the ability to activate induced systemic resistance (ISR) to a broad range of pathogens. Other strains have been shown to stimulate plant growth through the production of plant-growth-promoting (PGP) compounds, although both traits are rarely found together. This project focuses upon a novel, free-living, strain of T.

  • Metabolic engineering of microalgae with enhanced high value lipid production

    Microalgae produce a wide range of high-value compounds such as omega-3 Long Chain Polyunsaturated Fatty Acids (LC-PUFAs), carotenoids, antioxidants and also are a potential source of biofuel. Microalgal production of omega-3 LC-PUFAs is a relatively new emerging research field and significant efforts in strain development and cultivation technologies are required to reduce currently high production prices for algal biomass.

  • Functional Characterisation of AtELO1 in Arabidopsis thaliana using reverse genetics

    ELO genes were first identified in the yeast Saccharomyces cerevisiae where they are responsible for the synthesis of saturated Very Long Chain Fatty Acids (VLCFAs). Higher plants contain saturated and mono-unsaturated VLCFAs which are found in almost all lipid classes but are essential components of sphingolipids and essential for plant development. Interestingly, in land plants VLCFAs synthesis is mediated by the KCS genes, a gene family completely unrelated to the ELO genes. Arabidopsis thaliana contains 21 KCS paralogues with various degrees of tissue specificity.

  • Host plant colonisation by the model pest aphid, Myzus persicae

    Preventing crop losses to pests by host plant resistance plays an important role in food security and sustainable agriculture. The project will elucidate the molecular mechanisms influencing how a model pest species colonises host plants. It will focus on the interaction of peach-potato aphid, Myzus persicae, with potato and will investigate a wild potato species (Solanum stoloniferum) that is aphid resistant and the cultivated potato (Solanum tuberosum) which is susceptible.

  • Unravelling interactions between cereal aphids and ancestral wheat lines to elucidate mechanisms of aphid resistance.

    By safeguarding the yield potential of our crops, crop protection forms an integral part of food security. Wheat is the dominant crop for human consumption in temperate countries and population growth, coupled with per capita increase in consumption drives demand which is expected to keep rising. Currently aphid damage to crops is controlled mainly by insecticide treatments but selection of resistance to these compounds is now widespread and highly resistant populations are present in most countries.

  • Monitoring and investigating altered fungicide sensisitivity in UK field populations of Pyrenopeziza brassicae, the cause of light leaf spot in oilseed rape

    Pyrenopeziza brassicae (Pb) causes light leaf spot (LLS), one of the most important oilseed rape (OSR) diseases in the UK, with an annual loss in excess of £140 million in 2014. Although OSR cultivars resistant to light leaf spot are available, even the most resistant commercial cultivars can still develop LLS under favourable weather conditions. Consistent control relies on the application of systemic fungicides.

  • Metabolic engineering of cowpea roots to combat striga parasitic weeds

    Parasitic weeds from the Striga genus destroy subsistence cereal crops that resource-poor farming communities rely on in sub-Saharan Africa, causing famine and societies to abandon infested areas. Rothamsted Research and the International Centre of Insect Physiology and Ecology discovered that intercropping cereals with a forage legume from the Desmodium genus prevents the weed parasitizing cereals. Desmodium root exudates actively inhibit striga parasitism of cereals and the strategy is now deployed by over 70,000 farmers in East Africa (Kenya, Tanzania, Ethiopia). 

  • Discovery of novel alleles to enhance bound phenolic content of wheat grain

    This project addresses the BBSRC priority “Food, nutrition and health”, specifically “research to enhance the bioavailability of micro-nutrients and other components beneficial to health”. Wheat grain constitutes a large component of the human diet. Recently there has been much interest in the health benefits associated with phenolic compounds present in wheat grain, the majority of which is ferulic acid and coumaric acid ester-linked within cell walls in the grain outer layers, with lesser amounts of free and conjugated forms.

  • Characterisation of the plant N-end rule, a protein degradation pathway of agricultural importance

    Turnover of regulatory proteins is a hugely important control mechanism in signalling and development in plants. Recently, we discovered that a specialised pathway of targeted protein degradation- the N-end rule pathway- regulates ABA signalling and seed oil mobilisation (Holman et al., 2009 PNAS USA) and acts as a sensor for hypoxia and nitric oxide (Gibbs et al., 2011 Nature; 2014, Mol. Cell). Others have shown important roles in leaf development and senescence (Graciet et al., 2011 TIPS).

  • Lipid metabolism and plant defence

    As the population grows, so must the amount of food produced. Three mutants of the model organism Arabidopsis thaliana display an enhanced disease resistance (EDR) phenotype to powdery mildew. In order to get a better understanding of why the plants are resistant to disease and if it is possible to exploit this trait in crops this project aims to utilise metabolomics, transcriptomics and microscopy to understand the mechanism of the EDR phenotype.

  • Securing seed oil synthesis: what can we learn from the extremities?

    Vegetable oils underpin the global bio-based economy, securing the supply of these oils is the challenge facing modern Agriculture.  To meet this challenge, it is essential to identify the controlling factors that are influenced by environmental stress and regulate the flux of fatty acids through various oil assembly pathways to produce seed oils. Much progress has been made in seed acyl-lipid metabolism using model species; this project will use the extremophile oilseed species to identify lipid associated stress tolerance strategies.
