Proline-2′-deoxymugineic acid, a phytosiderophore analog, drives beneficial rhizobacterial community formation to promote peanut micronutrition

Proline-2′-deoxymugineic (PDMA) significantly altered the bacterial community in the peanut rhizosphere.• PDMA resulting in a substantial increase of beneficial bacteria related with micronutrition in plant and soil, especially Actinobacteriota.• PDMA application led to the development of a tight, stable microbial network and fosters microbial communication in the rhizosphere.
