Non-Specific Interactions of Rhizospheric Microbial Communities Support the Establishment of Mimosa acutistipula var. ferrea in an Amazon Rehabilitating Mineland

Mimosa acutistipula var. ferrea (Fabaceae) is endemic to ferruginous tropical rocky outcrops in the eastern Amazon, also known as canga. Canga are often associated with mining activities and target of protection rehabilitation projects. M. stands out this biodiversity hotspot high growth rates, even rehabilitating minelands (RMs). However, little about diversity soil microorganisms interacting canga RMs. This study analyzed rhizosphere-associated bacterial fungal microbial communities growing an RM a native shrub The phylum Ascomycota was dominant taxa identified rhizosphere (RA: 98.1) 93.1). phyla Proteobacteria 54.3) Acidobacteria 56.2) were RM, respectively. Beneficial genera such Bradyrhizobium, Rhodoplanes, Paraconiothyrium both areas. analyses showed that differed between adapted (i.e., Rasamsonia, Scytalidium, Roseiarcus, Rhodomicrobium) lacking RM. influences microbe-mediated processes, affecting long-term success. results established non-specific interactions microorganisms, including beneficial nitrogen-fixing bacteria, mycorrhizal fungi, other endophytes, well for their importance plant adaptation survival. High levels microbe association plant’s ability recruit wide range help explain acutistipula’s success minelands.
