Discovery of new genomic configuration of mating-type loci in the largest lineage of lichen-forming-fungi

The genetic architecture of mating-type loci in lichen-forming fungi has been characterized in very few taxa. Despite the limited data, and in contrast to all other major fungal lineages, arrangements that have both mating-type alleles in a single haploid genome have been hypothesized to be absent from the largest lineage of lichen-forming fungi, the Lecanoromycetes. We report the discovery of both mating-type alleles from the haploid genomes of three species within this group. Our results demonstrate that Lecanoromycetes are not an outlier among Ascomycetes.
