AGRIBIOME

The main goals of AGRIBIOME are to (i) identify microbial hubs (highly connected taxa in microbial networks) regulated by plant genotype while mitigating biotic stresses, (ii) develop molecular markers for plant traits associated with recruitment of beneficial microbes, (iii) establish a new generation of plant probiotics that predictably and consistently enhance crop resilience and (iv) utilize knowledge on microbiome engineering to predict crop disease resistance towards holobiont-based breeding programmes. AGRIBIOME started in 2020 by genotyping a panel of 254 pea lines. These pea lines had previously been phenotyped for their resistance towards root rot when grown in infested field soil under controlled conditions.

AGRIBIOME项目的核心目标包括：(i) 鉴定受植物基因型调控且可缓解生物胁迫的微生物枢纽（microbial hubs，即微生物网络中连接度极高的类群）；(ii) 开发与有益微生物招募相关的植物性状分子标记；(iii) 构建可稳定且可预测地提升作物抗逆性的新一代植物益生菌；(iv) 借助微生物组工程相关知识，预测作物抗病性，以支撑基于全共生体（holobiont）的育种计划。
该项目于2020年启动，首先对254份豌豆品系组成的群体开展基因分型工作。此前，研究人员已在受控条件下，将这些豌豆品系种植于侵染性田间土壤中，完成了其根腐病抗性的表型鉴定。
