Take-all disease, caused by the soil-borne ascomycete fungus Gaeumannomyces graminis var. tritici (Ggt), is the most damaging root disease of wheat in the UK and worldwide. The fungus invades the roots and destroys the vascular tissue, hindering the plants ability to uptake water and nutrients from the soil. Closely related Phialophora fungal species occur naturally in arable and grassland soils and have considerable potential to suppress take-all disease and to help understand the response of wheat to non-pathogenic / endophytic and pathogenic root invading fungi. The main objective of this project is to understand and characterise the Phialophora-wheat interaction. The infection biology and molecular aspects occurring during root colonisation will be explored using in depth bioimaging analyses and comparative transcriptomic experiments while field trials and controlled environment experiments will be developed to characterise the ability of wheat varieties to sustain Phialophora populations.

全蚀病，由土壤传播的子囊真菌禾顶囊菌变种引起。小麦锈病（Ggt）是英国和全世界小麦最具破坏性的根病。真菌侵入根部并破坏维管组织，阻碍植物从土壤中吸收水分和养分的能力。密切相关的瓶霉属真菌物种自然存在于耕地和草地土壤中，并且具有相当大的潜力来抑制全蚀病，并有助于了解小麦对非致病性/内生和致病性根入侵真菌的反应。本项目的主要目的是了解和验证瓶霉-小麦互作。将使用深入的生物成像分析和比较转录组实验来探索根定殖期间发生的感染生物学和分子方面，同时将开发田间试验和受控环境实验来表征小麦品种维持瓶霉种群的能力。
