Molecular diversity of rhizobia-nodulating native Mimosa of Brazilian protected areas.

Symbiotic Paraburkholderia have been increasingly studied in the past 20 years, especially when associated with Mimosa; however, studies with native/endemic species are still scarce. In this study, thirty strains were isolated from root nodules of native Mimosa paranapiacabae and M. micropteris in two locations of the Campos Gerais.

Phylogenetic diversity of rhizobia nodulating native Mimosa gymnas grown in a South Brazilian ecotone.

Floristic surveys performed in "Campos Gerais" (Paraná, Brazil), an ecotone of Mata Atlântica and Cerrado biomes, highlights the richness and relative abundance of the family Fabaceae and point out the diversity and endemism of Mimosa spp. Our study reports the genetic diversity of rhizobia isolated from root nodules of native/endemic Mimosa gymnas Barneby in three areas of Guartelá State Park, an important conservation unit of "Campos Gerais". Soils of the sample areas were characterized as sandy, acid, poor in nutrients and organic matter.
