Dataset on culturable endophytic bacteria and fungi associated with selected native plants from La Araucanía Region, south-central Chile
Year: 2026
Type: data-paper
Abstract: This dataset comprises molecular sequences and standardized metadata for 350 culturable bacterial isolates and 224 culturable fungal isolates. The isolates were recovered from surface-disinfected plant tissues, including roots, leaves, and seeds, depending on the host taxon and sampling site. Samples were collected from 12 identified native plant taxa and one unidentified host taxon at 21 sites distributed across the Andean foothills and mountains, Coastal Range foothills, and the Intermediate Depression of La Araucanía Region, south-central Chile. The host plants included Gaultheria poeppigii, Gaultheria pumila, Empetrum rubrum, Nothofagus alpina, Araucaria araucana, Chloraea magellanica, Gevuina avellana, Nothofagus obliqua, Sophora cassioides, Tristerix corymbosus, Persea lingue, and Prumnopitys andina , as well as one unidentified native plant taxon. Plant material was collected during the austral spring and summer, between October 2024 and March 2025, and fungi and bacteria were isolated using potato dextrose agar and Luria-Bertani agar, respectively. Bacterial 16S rRNA gene fragments were amplified using primers 27F/1492R, whereas fungal ITS regions were amplified using ITS1/ITS4, and the resulting amplicons were subjected to Sanger sequencing. Taxonomic comparisons were based on BLASTn searches against GenBank, with sequence identity values used to evaluate the level of similarity to the closest taxonomic matches. Metadata describing host identity, sampled tissue, sampling location, and taxonomic assignment were also included. The sequences were deposited in the GenBank database under accession numbers QB177587-QB177936 for bacteria and QB181827-QB182050 for fungi, and the complete curated dataset was deposited in the Zenodo repository. These data are useful for comparative studies of culturable bacteria and fungi associated with selected native plants from southern South America and for identifying candidate native isolates for subsequent functional characterization and potential biotechnological applications.
