Iron bioavailability is often limited especially in calcareous soils. Trichoderma harzianum strongly improves plant iron uptake and growth However, little known about the mechanisms by which T. mobilizes Here, model strain NJAU4742 a synthetic microbial community (SynCom) was used to show that efficacy of enhancing nutrition soils depends on soil microbiome. Enhanced iron-mobilization functions SynCom were observed presence NJAU4742. Concurrently, improved capacity enriching strains are able do so. Finally, Chryseobacterium populi identified as key driver mobilization, while their synergistic colonization further enhances this process. This study unveils pivotal mechanism NJAU4742-mediated re-structuring microbiome ameliorates nutrition.

Introduction The rhizosphere is the zone of soil surrounding plant roots that directly influenced by root exudates released plant, which select microorganisms. resulting microbiota plays a key role in health and development enhancing its nutrition or immune response protecting it from biotic abiotic stresses. In particular, growth-promoting rhizobacteria (PGPR) are beneficial members this represent great hope for agroecology, since they could be used as bioinoculants sustainable crop production. Therefore, necessary to decipher molecular dialog between PGPR order promote establishment rhizosphere, required their functions. Methods Here, ability rapeseed ( Brassica napus ), pea Pisum sativum ryegrass Lolium perenne ) attract feed three Bacillus subtilis , Pseudomonas fluorescens Azospirillum brasilense was measured compared, these responses involved microbiota. Results Our results showed differentially attracted fed PGPR. For all bacteria, were most attractive induced fastest growth, while allowed highest biomass performance generally lower, variable observed bacteria. addition, P.
