Abstract
The rhizosphere of plants contains a diversity of microorganisms, some of which play an important role in the growth and development of the host plant. In this work, the diversity of fungi and bacteria associated to the rhizosphere of Tabebuia chrysantha and T. billbergii plants was analyzed. The molecular identification was performed by sequencing the ITS and 16S rDNA for fungi and bacteria, respectively. The analysis of the rDNA sequences of the rhizosphere of T. billergii showed that for domain Eukaria, the most abundant phyla were Glomeromycota (56%) and Ascomycota (39%), and for domain Bacteria, the phylum Firmicutes (19.17%) was the most abundant followed by Actinobacteria (14.90%) and Proteobacteria (8.94%). In the rhizosphere of T. chrysantha the most abundant phylum of Eukaria was Ascomycota (98%), and for Bacteria the most representative phyla were Proteobacteria (18.61%) and Actinobacteria (11.93%). A diversity of genera and species of fungi and bacteria was observed, to be more significant in T. chrysantha than T. billbergii. The taxonomic assignment of metagenomic sequences revealed a homology associated with genomic sequences of 546 bacteria and 147 fungi in T. chrysantha and 154 bacteria and 122 fungi in T. billbergii.
