In natural environments, it has been shown that orchids interact with multiple microorganisms including various species of fungi that colonize their tissues. The diversity of these fungi associated with orchid roots is still being described along with the ecological role they play when interacting with the orchids. In this study, we evaluated the richness and diversity of the endophytic and mycorrhizal fungi associated with the roots of Maxillaria acuminata, a common epiphytic orchid species from a tropical montane forest in southern Ecuador. We characterized the fungal communities by sequencing the ITS2 region of the nrDNA with Illumina MiSeq technology. In total, 843 fungal OTUs were uncovered using a 97% sequence similarity. The highest percentage of OTUs belonged to the Agaricomycetes class, Basidiomycota. Interestingly, the most frequent trophic guild from the analyzed OTUs was assigned as saprophytic. Also, some groups of orchid mycorrhizal-forming fungi were detected, including members within the families Ceratobasidicaceae, Serendipitaceae, Tulasnellaceae, and in the order Atractiellales. We discuss the potential influence of this diverse group of root-associated endophytic fungi on the development and survival of M. acuminata in the tropical forests of southern Ecuador. |
