Postglacial History of a Widespread Wood-Decaying Fungus in Europe Suggests Migration out of Multiple Refugia Followed by Admixture. Molecular Ecology.

While postglacial migration patterns have been well-studied in plants and animals in Europe, the same is not true for microorganisms such as fungi, and it remains unclear whether fungi have followed the same postglacial migration trajectories. In this study, we infer the postglacial history of the widespread wood-decay fungus Trichaptum abietinum in Europe. We investigate whether this fungus resided in multiple glacial refugia, as observed in many plants and animals, and how it migrated following the retreat of the ice. Population genomic analyses of T. abietinum suggest at least two glacial refugia in Europe: a southern refugium extending from Portugal to the Caucasus (potentially formed by several earlier distinct refugia), an eastern refugium and a potential third western refugium. Expansion from these refugia followed by migration and secondary contact has led to a complex genomic pattern of what we call the Mediterranean, Boreal, Atlantic and Central European admixed groups. From the southern and potential western refugia there have likely been northwards expansions resulting in the Mediterranean and Atlantic groups, while the Boreal group probably expanded westwards from the eastern refugium. A contact zone is present in Central Europe, where the Mediterranean and Boreal groups are admixing. In these admixed individuals, the second half of their largest scaffold is entirely inherited from the Boreal group, indicating either strong selection or genomic incompatibilities. In Scandinavia, the Atlantic and Boreal groups are in close contact but with limited admixture. Tajima's D and analyses of linkage disequilibrium decay support a recent history of contraction and expansion of this fungus in Europe. We conclude that the postglacial migration patterns in T. abietinum resemble those observed in several plants and animals, suggesting multiple glacial refugia followed by admixture during northward and westward expansions.

Reproductive barriers between sister species of the mushroom-forming fungi tend to be stronger in sympatry, leading to speculation on whether they are being reinforced by selection against hybrids. We have used population genomic analyses together with in vitro crosses of a global sample of the wood decay fungus Trichaptum abietinum to investigate reproductive barriers within this species complex and the processes that have shaped them. Our phylogeographic analyses show that T. abietinum is delimited into six major genetic groups: one in Asia, two in Europe, and three in North America. The groups present in Europe are interfertile and admixed, whereas our crosses show that the North American groups are reproductively isolated. In Asia, a more complex pattern appears, with partial intersterility between subgroups that likely originated independently and more recently than the reproductive barriers in North America. We found pre-mating barriers in T. abietinum to be moderately correlated with genomic divergence, whereas mean growth reduction of the mated hybrids showed a strong correlation with increasing genomic divergence. Genome-wide association analyses identified candidate genes with programmed cell death annotations, which are known to be involved in intersterility in distantly related fungi, although their link here remains unproven. Our demographic modeling and phylogenetic network analyses fit a scenario where reproductive barriers in Trichaptum abietinum could have been reinforced upon secondary contact between groups that diverged in allopatry during the Pleistocene glacial cycles. Our combination of experimental and genomic approaches demonstrates how T. abietinum is a tractable system for studying speciation mechanisms.

Abstract To understand how species evolve and adapt to changing environments, it is important to study gene flow and introgression due to their influence on speciation and radiation events. Here, we apply a novel experimental system for investigating these mechanisms using natural populations. The system is based on two fungal sister species with morphological and ecological similarities occurring in overlapping habitats. We examined introgression between these species by conducting whole genome sequencing of individuals from populations in North America and Europe. We assessed genome-wide nucleotide divergence and performed crossing experiments to study reproductive barriers. We further used ABBA–BABA statistics together with a network analysis to investigate introgression, and conducted demographic modelling to gain insight into divergence times and introgression events. The results revealed that the species are highly divergent and incompatible in vitro. Despite this, small regions of introgression were scattered throughout the genomes and one introgression event likely involves a ghost population (extant or extinct). This study demonstrates that introgression can be found among divergent species and that population histories can be studied without collections of all the populations involved. Moreover, the experimental system is shown to be a useful tool for research on reproductive isolation in natural populations. Abstract We studied population histories with demographic modelling and found introgression between highly divergent fungal sister species, involving a ghost population.

Iron is an indispensable element that participates as an essential cofactor in multiple biological processes. However, when present in excess, iron can engage in redox reactions that generate reactive oxygen species that damage cells at multiple levels. In this report, we characterized the response of budding yeast species from the Saccharomyces genus to elevated environmental iron concentrations. We have observed that S. cerevisiae strains are more resistant to high-iron concentrations than Saccharomyces non-cerevisiae species. Liquid growth assays showed that species evolutionarily closer to S. cerevisiae, such as S. paradoxus, S. jurei, S. mikatae, and S. arboricola, were more resistant to high-iron levels than the more distant species S. eubayanus and S. uvarum. Remarkably, S. kudriavzevii strains were especially iron sensitive. Growth assays in solid media suggested that S. cerevisiae and S. paradoxus were more resistant to the oxidative stress caused by elevated iron concentrations. When comparing iron accumulation and sensitivity, different patterns were observed. As previously described for S. cerevisiae, S. uvarum and particular strains of S. kudriavzevii and S. paradoxus became more sensitive to iron while accumulating more intracellular iron levels. However, no remarkable changes in intracellular iron accumulation were observed for the remainder of species. These results indicate that different mechanisms of response to elevated iron concentrations exist in the different species of the genus Saccharomyces.

Balancing selection, an evolutionary force that retains genetic diversity, has been detected in multiple genes and organisms, such as the sexual mating loci in fungi. However, to quantify the strength of balancing selection and define the mating-related genes require a large number of strains. In tetrapolar basidiomycete fungi, sexual type is determined by two unlinked loci, MATA and MATB. Genes in both loci define mating type identity, control successful mating and completion of the life cycle. These loci are usually highly diverse. Previous studies have speculated, based on culture crosses, that species of the non-model genus Trichaptum (Hymenochaetales, Basidiomycota) possess a tetrapolar mating system, with multiple alleles. Here, we sequenced a hundred and eighty strains of three Trichaptum species. We characterized the chromosomal location of MATA and MATB, the molecular structure of MAT regions and their allelic richness. The sequencing effort was sufficient to molecularly characterize multiple MAT alleles segregating before the speciation event of Trichaptum species. Analyses suggested that long-term balancing selection has generated trans-species polymorphisms. Mating sequences were classified in different allelic classes based on an amino acid identity (AAI) threshold supported by phylogenetics. 17,550 mating types were predicted based on the allelic classes. In vitro crosses allowed us to support the degree of allelic divergence needed for successful mating. Even with the high amount of divergence, key amino acids in functional domains are conserved. We conclude that the genetic diversity of mating loci in Trichaptum is due to long-term balancing selection, with limited recombination and duplication activity. The large number of sequenced strains highlighted the importance of sequencing multiple individuals from different species to detect the mating-related genes, the mechanisms generating diversity and the evolutionary forces maintaining them.

The genomes of hybrids often show substantial deviations from the features of the parent genomes, including genomic instabilities characterized by chromosomal rearrangements, gains, and losses. This plastic genomic architecture generates phenotypic diversity, potentially giving hybrids access to new ecological niches. It is however unclear if there are any generalizable patterns and predictability in the type and prevalence of genomic variation and instability across hybrids with different genetic and ecological backgrounds. Here, we analyzed the genomic architecture of 204 interspecific Saccharomyces yeast hybrids isolated from natural, industrial fermentation, clinical, and laboratory environments. Synchronous mapping to all eight putative parental species showed significant variation in read depth indicating frequent aneuploidy, affecting 44% of all hybrid genomes and particularly smaller chromosomes. Early generation hybrids with largely equal genomic content from both parent species were more likely to contain aneuploidies than introgressed genomes with an older hybridization history, which presumably stabilized the genome. Shared k-mer analysis showed that the degree of genomic diversity and variability varied among hybrids with different parent species. Interestingly, more genetically distant crosses produced more similar hybrid genomes, which may be a result of stronger negative epistasis at larger genomic divergence, putting constraints on hybridization outcomes. Mitochondrial genomes were typically inherited from the species also contributing the majority nuclear genome, but there were clear exceptions to this rule. Together, we find reliable genomic predictors of instability in hybrids, but also report interesting cross- and environment-specific idiosyncrasies. Our results are an important step in understanding the factors shaping divergent hybrid genomes and their role in adaptive evolution.

Full text in Research Archive Show summary
The domestication of Saccharomyces cerevisiae, as the result of its adaptation to human-manipulated processes, has been well analyzed by both phenotypic and genomic approaches. However, in other yeast species with industrial applications, such as Saccharomyces uvarum, these studies are very limited. To deepen knowledge about possible domestication in S. uvarum, an analysis of the genetic diversity of a series of S. uvarum strains isolated from different habitats was performed. Our results show that the greatest S. uvarum population diversity worldwide is observed in Patagonia, where strains of this species can be isolated from industrial and traditional fermentations as well as from natural environments. This greater Patagonian diversity is due to the presence of strains belonging to two genetically differentiated populations, South America B (SA-B), and Holarctic/South America A (H/SA-A). The H/SA-A population of Patagonia is directly related to apple fermentation environments, mainly from cider fermentations but also, to a lesser extent, from traditional apple chicha. Our data suggest that strains from the Holarctic population colonized Patagonia. This is possibly associated with the introduction of apple trees by European immigrants, since the Spanish colonization of Chile in the 16th century and the introduction of new apple tree cultivars in the upper valley of the Negro River, Argentina, during the 19th century. During this process of colonization, Holarctic strains hybridized with SA-B yeasts, generating a series of admixed strains, mainly present in the traditional apple chicha fermentations.

Trichaptum abietinum (Dicks.) Ryvarden (Hymenochaetales) is a pioneer wood rot mushroom common across the Northern Hemisphere, usually growing on conifer wood. The species has emerged in recent years as a model for mushroom genomics, and extensive genomic resources are available. Here, we have analyzed patterns of gene presence-absence variation across a dataset covering T. abietinum known intraspecific geographical and genetic diversity. Our results suggest that Trichaptum abietinum has a large proportion of its genome under Presence-Absence variation, over 40% of all genes for any particular strain. This pattern seem to be common across Agaricomycetes, but not across other groups of Fungi. Core and accessory genes have distinct properties. Core genes also tend to cluster towards chromosome centers, while accessory genes are more abundant at the extremes. Core genes tend to be longer, have more introns and appear closer to other genes. Distribution of Accessory genes across the species depends on genetic distance, but this variable alone can only explain a fraction of the observed pattern. Unlike most other groups of fungi that tend to be haploid, Agaricomycetes spend most of their life cycle as a dikaryotic mycelium. Cell division in this mycelium is typically tightly regulated, which would be unnecessary were this a simple diploid. We hypothesize that extensive PAV has the potential of causing interference during mitotic recombination events, thus promoting genomic unstability. This is then prevented by keeping the two nuclei separated until meiosis. This life cycle would allow these fungi to access a much larger gene pool than it would be possible for any single haploid genet.

Evolution has brought to life an immense diversity of forms, lifestyles and species in the fungi. Yet our knowledge about how this diversity has been generated remains sparse. I have taken a closer look at evolution in a group of wood decay fungi in genus Trichaptum, with the aim of gaining more insight about the speciation process in fungi. Trichaptum species are common, easy to culture, and can be crossed in the lab. Moreover, they have varying degrees of reproductive barriers, and these attributes make them suitable for speciation studies as the development of reproductive barriers is central to the speciation process. I have established a comprehensive culture collection that have been put through crossing experiments and whole genome DNA sequencing to investigate the evolutionary history of different Trichaptum lineages and the genetic causes of their reproductive barriers. Analyses of the sequenced genomes revealed multiple hybridization events, which speaks to the importance of reticulate evolution in these fungi. The studies cover evolution in genus Trichaptum at multiple scales, from the relatively recent changes occurring within Europe in T. abietinum, to changes that have happened between continents and distinctly differentiated species across larger time spans. Altogether this work demonstrates how multiple evolutionary forces across different temporal and genetic scales have interacted to shape the current diversity and genomic landscape in Trichaptum.
