Root-secreted coumarins and the microbiota interact to improve iron nutrition in Arabidopsis. Harbort and Hashimoto et al. Cell Host & Microbe 2020

We report a plant-beneficial interaction between Arabidopsis thaliana and the root microbiota under iron deprivation that is dependent on the secretion of plant-derived coumarins.
The Bioproject includes
Culture independent 16S rRNA gene amplicon sequencing of root-associated bacterial microbiota of plants grown in soils with contrasting iron availability.RNASeq of root tissue of arabidosis thaliana and mutants grown in a gnotobiosystem with differing iron availability regimes.

本研究报道了拟南芥（Arabidopsis thaliana）与根系微生物群在缺铁条件下的植物有益互作，该互作依赖于植物分泌的香豆素。
本生物项目（Bioproject）包含以下研究内容：对种植于铁有效性存在差异的土壤中的植物的根系附生细菌微生物群开展非培养依赖型16S rRNA基因扩增子测序；对在不同铁供给条件的限菌培养系统中培养的拟南芥（Arabidopsis thaliana）及其突变体的根组织进行RNA测序（RNASeq）。
