説明
This resource is a report describing the identification and diversity of 43 fungi isolated from Peltigera lichen thalli (P. frigida, P. fuscopraetextata, P. rufescens, and P. antarctica) and 2 fungi isolated from Peltigera fuscopraetextata lichen substrate collected in southern Chile. The fungi were identified by sequencing the ITS marker and subsequent phylogenetic analyses, and a great diversity of ascomycete fungi was found, belonging to 6 classes, 12 orders, 13 families, and 16 genera. Only 33% of the strains were identified at the species level, 58% at the genus level, and 9% at the family level. Additionally, strains presumably belonging to new species yet to be described were also isolated. To our knowledge, this report represents the first record of these ascomycete fungi species on Peltigera lichens from southern Chile, and along with the deposited basidiomycete yeasts in this database, contributes to clarify the fungal diversity present in the Peltigera lichen mycobiome. Georeferencing was included for all specimens. The diversity of fungi found in this study highlights the importance of investigating the mycobiome of lichens, which can serve as potential sources of novel and biologically active compounds.

プロジェクトデータ
This study is part of a larger project (FONDECYT 1181510) aimed at studying the microbiome of Peltigera lichens and their symbiotic roles. Specifically, this study focuses on basidiomycete yeasts and ascomycete fungi associated with thalli and substrates (i.e. soil) of four Peltigera lichen species (P. frigida, P. fuscopratextata, P. antarctica, and P. rufescens) from the Aysén and Magallanes regions of southern Chile. Two of these species have been reported as endemic to the extreme south of South America (P. frigida and P. antarctica), which highlights the importance of studying biodiversity in poorly understood environments. While the study's main objective was to analyze basidiomycete yeasts, we were able to isolate and identify a diverse array of ascomycete fungi, which is an important contribution to understanding the mycobiome of Peltigera lichens. The findings from this project could be considered in decision-making regarding the management and design of protected areas for biodiversity conservation in Chile, considering often-neglected components. Furthermore, it provides evidence of the significance of lichens as complex miniature ecosystems, which harbor a variety of microbial communities, underscoring the importance of their preservation.

| Study Area Description | Samples of each lichen species (P. frigida, P. fuscopratextata, P. antarctica, P. rufescens) and their substrates were collected at four sites in southern Chile, two in the Aysén Region: (1) Coyhaique National Reserve and (2) Patagonia National Park, Tamango sector; and two in the Magallanes Region: (3) Karukinka Natural Park and (4) Navarino Island, near Puerto Williams. At each site, two environmental contexts were included, grassland and forest, and each species was collected considering its distribution: P. frigida and P. fuscopratextata in forests, and P. antarctica and P. rufescens in grasslands. Samples were collected in different sampling years between 2013 and 2020. These samples are currently part of the Peltigera lichen collection of southern Chile, from the Microbial Ecology Laboratory at Universidad de Chile. The predominant vegetation cover in the sites corresponds to mature and young forests of Nothofagus pumilio and Patagonian steppe. Permits for sampling in the protected areas were obtained from CONAF (Corporación Nacional Forestal). |
| 研究の意図、目的、背景など（デザイン） | The main objective of this project is to determine the diversity of basidiomycete yeasts associated with Peltigera lichens from southern Chile and the specificity of the main mycobiont for them. However, also ascomycete fungi were isolated from these samples. The first step was to molecularly identify the symbiotic pairs of the lichen species P. frigida, P. fuscopraetextata, P. antarctica, and P. rufescens. Once the study species were identified, we proceeded to evaluate the diversity of fungi associated with the thalli and substrates of the four Peltigera lichen species using two proposed methodologies. The first method involved massive sequencing of amplicons obtained from thalli and substrates of the four study species, while the second method involved a culture-dependent approach. Isolation was performed from the thalli of these lichen species on three different culture media with an incubation temperature of 10°C in the dark. Fungi were isolated from all samples except thalli of P. fuscopraetextata from Coyhaique, probably due to the age of these samples. Isolates were identified by sequencing the ITS marker and subsequent phylogenetic analyses. In addition to the basidiomycete yeasts cultured, we also isolated ascomycete fungi from these same lichen species, indicating a great diversity of ascomycetes that contribute to describing the mycobiome of Peltigera lichens. Phylogenetic analyses suggest the presence of several new ascomycete species that have not yet been reported and need to be described in further studies. |
収集方法
Fungi were isolated from thalli of four lichen species of the genus Peltigera (P. frigida, P. fuscopraetextata, P. antarctica, P. rufescens). The thalli were washed twice with sterile distilled water and subsequently macerated. They were then inoculated onto three culture media (Yeast Malt Agar, Potato Dextrose Agar, and a minimal agar medium without amino acids) supplemented with antibiotics. The cultures were incubated in the dark at 10°C for up to 60 days. Long-term preservation of yeast isolates was achieved at -20°C using cryotubes with sterile 15% glycerol, and a dehydrated gelatin drop method at room temperature with sterile 10% gelatin was used. Taxonomic identification was performed by sequencing the ITS marker and subsequent phylogenetic analyses. For the isolates obtained from P. fuscopraetextata substrate, the same procedure was followed, except that no washing step was performed.
