  • Title: Discovery of New Genomic Configuration of Mating-Type Loci in the Largest Lineage of Lichen-Forming Fungi.
    Author: White KH, Keepers K, Kane N, Lendemer JC.
    Journal: Genome Biol Evol; 2024 May 02; 16(5):. PubMed ID: 38686438.
    Abstract:
    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.
