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