Genomic regions determining sexual compatibility often display recombination suppression,
as occurs in sex chromosomes, plant self‐incompatibility loci and fungal mating‐type loci …

Gene expression differences between males and females are thought to be key for the
evolution of sexual dimorphism, and sex-biased genes are often used to study the molecular …

Fungal hybrids arise through the interbreeding of distinct species. This hybridization process
fosters increased genetic diversity and the emergence of new traits. Mechanisms driving …

Recombination is beneficial over the long term, allowing more effective selection. Despite
long-term advantages of recombination, local recombination suppression can evolve and …

Supergene regions maintain alleles of multiple genes in tight linkage through suppressed
recombination. Despite their importance in determining complex phenotypes, our empirical …

Although sex is now accepted as a ubiquitous and ancestral feature of eukaryotes, direct
observation of sex is still lacking in most unicellular eukaryotic lineages. Evidence of sex is …

In this editorial letter, we summarize the current challenges in the field of sex chromosome
evolution and introduce the 17 manuscripts which together provide insights into the diversity …

Heterokaryosis is a system in which genetically distinct nuclei coexist within the same
cytoplasm. While heterokaryosis dominates the life cycle of many fungal species, the …

Ascomycetes fungi are often prone to degeneration. Agricultural production of the prized
ascomycete mushroom Morchella importuna (black morel) typically suffers from reduced …

To explore the origin of the diversity observed in natural populations, many studies have
investigated the relationship between genotype and phenotype. In yeast species, especially …
