As pressure increases to reduce agricultural inputs, more efficient nutrient use has become an important breeding objective. Many plants including cereals such as barley form beneficial associations with soil microbes, which contribute to nutrient assimilation and protect against pathogen attack. Understanding the plant and microbial genetic traits that contribute to efficient colonisation thus has huge potential for the production of improved, low-input cereals and novel crop treatments. This studentship will investigate how strains of the beneficial soil bacterium Pseudomonas fluorescens colonise barley roots, and how this affects disease resistance and plant growth. Near-infrared and micromalting analysis will be performed with our industrial CASE partner; New Heritage Barley, to examine the effect of microbial colonisation on grain quality and flavour. The ultimate aim of this research will be to select and breed barley varieties that encourage beneficial microbial associations.

随着减少农业投入的压力增加，更有效地利用养分已成为重要的育种目标。许多植物，包括谷物，如大麦，与土壤微生物形成有益的联系，有助于营养吸收和抵御病原体的攻击。因此，了解有助于有效定殖的植物和微生物遗传性状对于生产改良的低投入谷物和新型作物处理具有巨大潜力。本研究将调查有益土壤细菌荧光假单胞菌菌株如何在大麦根部定植，以及这如何影响抗病性和植物生长。我们将与我们的工业合作伙伴CASE New Heritage Barley一起进行近红外和微麦芽分析，以检查微生物定殖对谷物质量和风味的影响。这项研究的最终目的是选择和培育能够促进有益微生物结合的大麦品种。
