Consequences of recombination for the evolution of the mating type locus in Chlamydomonas reinhardtii [PDF]

New Phytologist, 2019
Summary Rationale Recombination suppression in sex chromosomes and mating type loci can lead to degeneration due to reduced selection efficacy and Muller’s ratchet effects.

The Plot Thickens: Haploid and Triploid-Like Thalli, Hybridization, and Biased Mating Type Ratios in Letharia

Frontiers in Fungal Biology, 2021
The study of the reproductive biology of lichen fungal symbionts has been traditionally challenging due to their complex lifestyles. Against the common belief of haploidy, a recent genomic study found a triploid-like signal in Letharia.

An Overview of the Function and Maintenance of Sexual Reproduction in Dikaryotic Fungi

Frontiers in Microbiology, 2018
Sexual reproduction likely evolved as protection from environmental stresses, specifically, to repair DNA damage, often via homologous recombination. In higher eukaryotes, meiosis and the production of gametes with allelic combinations different from ...

Advances in Understanding Mating Type Gene Organization in the Mushroom-Forming Fungus Flammulina velutipes

G3: Genes, Genomes, Genetics, 2016
The initiation of sexual development in the important edible and medicinal mushroom Flammulina velutipes is controlled by special genes at two different, independent, mating type (MAT) loci: HD and PR. We expanded our understanding of the F.

Comparative Genomics of the Ectomycorrhizal Sister Species Rhizopogon vinicolor and Rhizopogon vesiculosus (Basidiomycota: Boletales) Reveals a Divergence of the Mating Type B Locus

G3: Genes, Genomes, Genetics, 2017
Divergence of breeding system plays an important role in fungal speciation. Ectomycorrhizal fungi, however, pose a challenge for the study of reproductive biology because most cannot be mated under laboratory conditions.

Identification and functional analysis of pheromone and receptor genes in the B3 mating locus of Pleurotus eryngii. [PDF]

PLoS ONE, 2014
Pleurotus eryngii has recently become a major cultivated mushroom; it uses tetrapolar heterothallism as a part of its reproductive process. Sexual development progresses only when the A and B mating types are compatible.

Evolution of Fluconazole-Resistant Candida albicans Strains by Drug-Induced Mating Competence and Parasexual Recombination

mBio, 2019
The clonal population structure of Candida albicans suggests that (para)sexual recombination does not play an important role in the lifestyle of this opportunistic fungal pathogen, an assumption that is strengthened by the fact that most C.

Linkage mapping identifies the sex determining region as a single locus in the Pennate diatom Seminavis robusta. [PDF]

PLoS ONE, 2013
The pennate diatom Seminavis robusta, characterized by an archetypical diatom life cycle including a heterothallic mating system, is emerging as a model system for studying the molecular regulation of the diatom cell and life cycle.

Development of a Molecular Marker Linked to the A4 Locus and the Structure of HD Genes in Pleurotus eryngii

Mycobiology, 2019
Allelic differences in A and B mating-type loci are a prerequisite for the progression of mating in the genus Pleurotus eryngii; thus, the crossing is hampered by this biological barrier in inbreeding.
