Colonization of pollen by bacterial pathogens and seed microbiome through plant domestication

种子中栖息着各种各样的微生物群落，它们对植物的生长和发育有重要的影响。这些群落的作用、细菌侵染种子的途径以及决定这些群落组成的因素仍然知之甚少。初步证据表明，野生祖先不仅在遗传组成和植物表型方面与驯化近亲不同，而且在与植物相关的微生物群落方面也不同。由于驯化过程已经显著改变了许多栽培作物的种子性质，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群。在这项研究中，我们将使用菜豆。作为模式植物来研究驯化是否改变了种子相关的微生物群。此外，我们将使用紫丁香假单胞菌PV。菜豆，一种种子传播的细菌性疾病，作为了解导致种子定植的感染途径的模式生物。BBSRC优先领域--可持续地提高农业生产--全球粮食安全

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
