Paraburkholderia spp. are the main rhizobial microsymbionts of Mimosa tenuiflora (Willd.) Poir. in soils of the Brazilian tropical dry forests (Caatinga biome).

Mimosa tenuiflora (Willd.) Poir. is widespread in southern and central American drylands, but little information is available concerning its associated rhizobia.

Vigna spp. Root-Nodules Harbor Potentially Pathogenic Fungi Controlled By Co-habiting Bacteria.

This study aimed to isolate, identify, and evaluate the pathogenicity of nodule-borne fungi of asymptomatic Vigna spp. plants, grown in soils from preserved tropical dry forests (Caatinga) areas and identify the occurrence of co-habiting bacteria from these plants, and which have potential to control the co-occurring pathogenic fungi. Fungi and bacteria were isolated from three Vigna species (V.
