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

这项LINK资助项目的提案将建立在目前正在进行的工作的坚实基础上，由现有的LINK项目、BBSRC资助，由工业界、苏格兰政府和NIAB信托基金直接资助。提出的研究将寻求更好地了解小麦根系的生长、形态和功能与养分和水分吸收的关系。描述各种冬小麦品种根系的方法将在受控的温室条件下和田间实施。该项目将通过开始预育种和开发适合当前和未来小麦生产的理想根系形态，为改善这种重要的英国作物的养分封存和转化奠定基础。该联盟将集中注意有效或加强利用资源，特别是氮和磷酸盐，并将考虑与水供应的相互作用。此外，将在田间条件下考虑与有益菌根真菌相互作用对养分封存的重要性以及土传致病真菌对敏感基因型的负面影响。最后，评估农药种皮对根系性能的潜在影响。总体而言，根系生物学研究导致养分吸收效率的提高，将有助于减少弥漫性污染，并将大幅减少小麦栽培中氮肥的使用，从而减少温室气体的排放
