Descripción
This resource represents to date the largest collection of basidiomycetes yeasts isolated from lichen thalli and the first collection of yeasts associated with Peltigera lichens. The Microbial Ecology Lab (Universidad de Chile) collection comprises 180 basidiomycetes yeasts isolated and identified from Peltigera lichen thalli (P. frigida, P. fuscopraetextata, P. rufescens and Peltigera ponojensis/monticola 11) collected from southern Chile. The isolates were identified by sequencing the ITS marker and subsequent phylogenetic analyses. A great diversity of basidiomycetes genera was found, belonging to the classes Agaricostilbomycetes, Cystobasidiomycetes, Microbotryomycetes and Tremellomycetes and to the orders Agaricostilbales, Cystobasidiales, Cystofilobasidiales, Filobasidiales, Holtermanniales, Sporidiobolales and Tremellales. Georeferencing included for all specimens.

Datos del proyecto
This study is part a broader project (FONDECYT 1181510) aiming to study the microbiome of Peltigera lichens and their role in the symbiosis of these lichens. In particular, this study focuses on basidiomycete yeasts associated with thalli and substrates (i.e. soil) of four Peltigera lichen species (P. frigida, P. fuscopratextata, Peltigera ponojensis/monticola 11 and P. rufescens) from the Aysen 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 Peltigera ponojensis/monticola 11), which brings special relevance to the study of biodiversity components of poorly studied environments such as those of southern Chile. It is important to note that so far there is no published work that has reported the presence and diversity of basidiomycete yeasts in the thalli of these Peltigera lichen species, and even less in the substrates where they grow. This is the first study on basidiomycete yeasts present in the mycobiome of Peltigera lichens and the substrates where they grow. The results obtained in this project provide information that could contribute to decision-making regarding the management and design of protected areas for the conservation of biodiversity in Chile, including components that are often not considered in this area. In addition, they will provide more evidence on the importance of lichens as complex miniature ecosystems, which harbor a diversity of microbial communities, and as such, the importance of knowing and preserving them. Some of the basidiomycete yeasts reported in association with lichens have a lichen-dependent mode of life, so it is very likely that the lichen species studied are reservoirs of hitherto unreported yeasts.

| Descripción del área de estudio | Samples of each lichen species (P. frigida, P. fuscopratextata, Peltigera ponojensis/monticola 11, P. rufescens) and their substrates were collected at four sites in southern Chile, two in the Aysen 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 Peltigera ponojensis/monticola 11 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). |
| Descripción del diseño | 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. The first step was the molecular identification of the symbiotic pairs of the lichen species P. frigida, P. fuscopratextata, Peltigera ponojensis/monticola 11 and P. rufescens. Once the study species were identified, we proceeded to evaluate the diversity of basidiomycete yeasts associated with the thalli and substrates of the four Peltigera lichen species. Two methodologies were proposed for this purpose. Massive sequencing of amplicons obtained from thalli and substrates of the four study species with specific primers for basidiomycetes (unpublished) and a culture-dependent method. Yeasts were isolated from the thalli of each lichen species from each study site. Isolation was performed on three different culture media and with an incubation temperature of 10°C in the dark. The isolates were identified by sequencing the ITS marker and subsequent phylogenetic analyses. Therefore, the results obtained from the isolation are complemented with massive sequencing to better describe the diversity of these yeasts in the thalli of the Peltigera lichens studied. |
Métodos de muestreo
Yeasts were isolated from thalli of four lichen species of the genus Peltigera (P. frigida, P. fuscopraetextata, Peltigera ponojensis/monticola 11, P. rufescens). The thalli were washed twice with sterile distilled water and subsequently macerated. They were seeded on three culture media (Yeast Malt Agar, Potato Dextrose Agar and a minimum agar medium without amino acids) supplemented with antibiotics. Cultures were incubated at 10°C in the dark 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 (Marangon et al., 2003; Baeza et al., 2009). Taxonomic identification was performed by sequencing the ITS marker and subsequent phylogenetic analyses
