The bacteriome of the halophyte Atriplex nummularia (old man saltbush) in salt-affected soils - an ecological model.

Halophytes, plants capable of growing under saline conditions, are an important source of bacteria with biotechnological potential for plant growth under extreme conditions. In this study, we evaluated the halophyte Atriplex nummularia bacteriome assemblage from three different salinized sites in northeastern Brazil with different edaphoclimatic characteristics, understanding the participation of the plant in the assembly of its microbiome. We sampled 30 specimens, from which the leaves, roots, and rhizospheric soil were subjected to 16S rRNA gene sequencing, bringing forth patterns of alpha and beta diversity, taxonomical composition, co-occurrence network, and the core microbiome of each compartment.
