根分泌物影响根际微生物群落结构的能力是一个一致的理解。然而，我们对植物发育、根系分泌物和微生物组组合之间的联系的认识是有限的。在这里，我们分析了根际细菌群落的结构与拟南芥在四个时间点对应的不同阶段的植物发育：幼苗，营养，抽薹和开花。总体而言，细菌群落结构没有显着差异，但我们观察到，在幼苗阶段的微生物群落是不同于其他发育时间点。在一个更接近的水平，门，如酸杆菌，放线菌，拟杆菌，蓝藻和特定属在这些门遵循不同的模式与植物发育和根系分泌物。这些结果表明，植物可以在不同的发育阶段选择一个微生物子集，大概是为了特定的功能。因此，根际微生物组的元转录组学分析显示，81个独特的转录本显著（P
There is a concerted understanding of the ability of root exudates to influence the structure of rhizosphere microbial communities. However, our knowledge of the connection between plant development, root exudation and microbiome assemblage is limited. Here, we analyzed the structure of the rhizospheric bacterial community associated with Arabidopsis at four time points corresponding to distinct stages of plant development: seedling, vegetative, bolting and flowering. Overall, there were no significant differences in bacterial community structure, but we observed that the microbial community at the seedling stage was distinct from the other developmental time points. At a closer level, phylum such as Acidobacteria, Actinobacteria, Bacteroidetes, Cyanobacteria and specific genera within those phyla followed distinct patterns associated with plant development and root exudation. These results suggested that the plant can select a subset of microbes at different stages of development, presumably for specific functions. Accordingly, metatranscriptomics analysis of the rhizosphere microbiome revealed that 81 unique transcripts were significantly (P
