Temperature variability and other climatic attributes linked to genomic features in the lichen-forming fungal genus Umbilicaria.

ABSTRACT:

Background

Many species of lichen-forming fungi exhibit large geographical ranges and broad thermal niches, making them excellent models for investigating the genomics of climate adaptation. In this study, we examined the impacts of climatic variables on genomic features in 11 Umbilicaria species. We compared PacBio genomes of individuals from the same species collected in different climate zones: alpine, cold temperate, or Mediterranean.

Results

Our findings revealed several links between climatic and genomic features: (1) Selection pressure: in each climate zone, specific genes are under strong selection. (2) Genomic feature correlations: certain temperature variables (BIO2: mean diurnal range, BIO4: seasonality, BIO6: minimum in coldest month, BIO7: annual range) are corr
