Rhizosphere Grand Challenge Single Cell Sequencing. The goal of this project is to comprehensively characterize the genomes of microorganisms found in the rhizosphere and endosphere of Arabidopsis thaliana. Organisms for study have been targeted based on their reproducible association with one or more Arabidopsis genotypes grown in natural soil. To obtain genomes from both culturable and unculturable fractions of the Arabidopsis microbiome, rhizosphere and endosphere samples were disaggregated and individual cells sorted by flow cytometry and amplified by MDA, then microbes of interest were identified by 16S rRNA sequencing and their whole genomes sequenced. Genomic sequences will be analyzed for genes participating in the plant-microbe symbiosis.

根际大挑战单细胞测序（Rhizosphere Grand Challenge Single Cell Sequencing）。本项目旨在全面解析拟南芥（Arabidopsis thaliana）根际与内生境中微生物的基因组特征。研究对象的筛选基于其与天然土壤中栽培的一种或多种拟南芥基因型存在可重复关联的特性。为获取拟南芥微生物组中可培养与不可培养组分的基因组信息，研究人员对根际及内生境样本进行解离处理，通过流式细胞术分选单个细胞并采用多重置换扩增（MDA）进行扩增；随后通过16S rRNA测序鉴定目标微生物，并对其全基因组进行测序。后续将对获得的基因组序列开展分析，以挖掘参与植物-微生物共生过程的基因。
