Mangrove forest trees play important ecological functions at the interface between terrestrial and marine ecosystems. However, despite playing crucial roles in plant health productivity, there is little information on microbiomes of tree species mangrove Thus, this study we aimed to characterize microbiome soil (rhizosphere) (root, stem, leaf endosphere) compartments widely distributed Rhizophora stylosa. Surprisingly, bacterial operational taxonomic units (OTUs) were only confidently detected rhizosphere soil, while fungal OTUs all compartments. The major phyla affiliated Proteobacteria, Actinobacteria, Planctomycetes, Chloroflexi. Several nitrogen-fixing detected, presence bacteria was confirmed by nifH gene based-PCR samples, indicating their involvement N acquisition focal ecosystem. We taxonomically (54 families, 83 genera) functionally diverse fungi R. stylosa mycobiome. Ascomycota (mainly Dothideomycetes, Eurotiomycetes, Sordariomycetes) most mycobiome, accounting for 86% total OTUs. found significant differences functional community composition among also OTU richness (p < 0.002) 0.001) results provide first associated indications
