This proposal for LINK funded project will build on a solid base of work currently underway, funded through existing LINK programmes, BBSRC, directly by industry, the Scottish Government and the NIAB Trust fund. The proposed study will seek to initiate a better understanding of wheat root growth, morphology and functional relationships with nutrient and water uptake. Methods to describe roots in a diverse range of winter wheat types will be implemented in controlled glasshouse conditions and in the field. The project will form the foundation for improving nutrient sequestration and conversion in this important UK crop through initiation of pre-breeding and development of ideal root ideotypes suitable for use in current and future wheat production. The consortium will concentrate on efficient or enhanced use of resources, especially nitrogen and phosphate and will consider interactions with water availability. In addition, the importance of interactions with beneficial mycorrhizal fungi on nutrient sequestration and the negative impact of soil-borne pathogenic fungi on susceptible genotypes will be considered under field conditions. Finally, the potential impact of agrochemical seed coats on root performance will be assessed. Overall, research in root biology leading to increases in nutrient uptake efficiency will contribute to reductions in diffuse pollution and will substantially reduce green house gas emission due a reduction in the use of nitrogen fertilisers in wheat cultivation

该链接资助的项目的这一建议将基于目前正在进行的稳固工作基础，该计划由现有的链接计划，BBSRC，行业，苏格兰政府和NIAB Trust Fund直接资助。拟议的研究将寻求更好地了解小麦根的生长，形态以及与养分和水吸收的功能关系。描述各种冬季小麦类型的根源的方法将在受控的玻璃屋条件下和现场实施。该项目将构成通过构成适合于当前和未来小麦生产的理想根部iDeytypes的预生产和发展理想的根部意识形态，以改善这种重要的英国农作物中的营养隔离和转化的基础。该财团将集中于有效或增强资源的使用，尤其是氮和磷酸盐，并将考虑与水的相互作用。此外，在田间条件下，将考虑与有益的菌根真菌相互作用对养分隔离以及土壤传播致病真菌对易感基因型的负面影响的重要性。最后，将评估农化学种子涂层对根部性能的潜在影响。总体而言，根系生物学的研究导致养分摄取效率的提高将导致弥漫性污染的降低，并且由于氮肥在小麦种植中使用氮肥而大大减少了温室气体排放
