Identifying host genetic factors shaping rhizosphere microbiome during root disease

豆科植物在农业多样化和可持续性方面发挥着重要作用。豌豆是一种有价值的豆类作物，因为它们有助于满足全球对植物蛋白日益增长的需求。然而，最近化学种子处理的取消使作物容易受到根系病害的影响。由真菌和卵菌病原体引起的根系腐烂会导致生长迟缓、产量下降和作物质量下降。为了应对这一挑战，该博士项目旨在了解(i)根腐病病原体如何影响根分泌物的组成并随后塑造土壤微生物群，以及（ii）与病原体诱导的根际微生物群变化相关的宿主遗传因素是什么。通过结合遗传学、宏基因组学和代谢组学的尖端技术，该项目旨在开发利用宿主遗传学来促进有益微生物种群并使其抵抗压力的策略。

Legumes play an important role in the diversification and sustainability of agriculture. Peas are a valuable legume crop as they contribute to meeting the growing demand for plant protein worldwide. However,recent removal of chemical seed treatments has made the crop vulnerable to root diseases. Root rots, caused by fungal and oomycete pathogens, can result in stunted growth, reduced yields, and lower cropquality. To tackle this challenge, this PhD project is being offered that aims to understand (i) how root rot pathogens influence composition of the root exudates and subsequently shape the soil microbiome and(ii) what are the host genetic factors associated with changes in the rhizosphere microbiome induced by the pathogen. By combining cutting-edge techniques in genetics, metagenomics, and metabolomics, theproject aims to develop strategies that use host genetics to promote beneficial microbial populations and makes it resilient against stress.
