Seeds are inhabited by diverse microbial communities that have important repercussions for plant growth and development. The role of these communities, the routes by which bacteria colonise seeds, and the factors that determine the composition of these communities remain poorly understood. Preliminary evidence suggests that wild progenitors differ from domesticated relatives not only in terms of their genetic composition and plant phenotype, but also with respect to their plant-associated microbial communities. As the process of domestication has significantly altered the properties of seeds in many cultivated crops, this raises the important question of whether domestication has also altered the seed microbiome. In this research study we will use Phaseolus spp. as model plants to investigate whether domestication has altered the seed-associated microbiome. Furthermore, we will use Pseudomonas syringae pv. phaseolicola, a seed-borne bacterial disease, as a model organism to understand the routes of infection leading to seed colonisation.BBSRC PRIORITY AREA ADDRESSED- Sustainably enhancing agricultural production- Global Food Security

种子中存在着对植物生长和发育有重要影响的各种微生物群落。这些社区的作用，细菌定植种子的途径，以及决定这些社区组成的因素仍然知之甚少。初步证据表明，野生祖先与驯化的亲属不仅在其遗传组成和植物表型方面不同，而且在其与植物相关的微生物群落方面也不同。由于驯化过程显著改变了许多栽培作物种子的特性，这就提出了一个重要的问题，即驯化是否也改变了种子微生物组。在这项研究中，我们将使用菜豆属。作为模式植物来研究驯化是否改变了种子相关的微生物组。此外，我们将使用假单胞菌pv.粮农组织/粮农组织
