Sex in the Mucoralean fungi.

Abstract

Sexual development is extant in virtually all eukaryotic species, including throughout the kingdom Fungi. Positioned within the opisthokonts along with metazoans, fungi serve as model systems to elucidate the genetics and impact of sexual development. Basal fungal lineages such as the Mucoralean fungi provide a unique basis to study sexual reproduction, in which common ancestral traits found in both animal and fungal lineages may be conserved. This review discusses the sexual development, sex loci, and evolution of the sex locus in the Mucoralean fungi, which sheds light on our understanding of the evolution and functions of sex.
