A Third Multiallelic Mating-type Locus in Physarum polycephalum

open access: yesMicrobiology, 1987
SUMMARY: Sexual development (crossing) in Physarum polycephalum occurs when two haploid amoebae fuse to form a diploid plasmodium. The imz locus influences the maximum pH at which crossing can occur. A new allele of imz has been identified, bringing the total number of alleles to three.

Role of α2 Protein in Donor Locus Selection during Mating Type Interconversion [PDF]

open access: yesMolecular and Cellular Biology, 1997
The homeodomain protein alpha2p plays a role both in transcriptional repression in the process of cell type determination and in donor selection during mating interconversion. We have explored the mechanism of alpha2p-directed donor selection by examining the effects on donor preference of mutants deficient in alpha2p-mediated transcriptional ...

Population genetics of trypanosoma brucei rhodesiense: clonality and diversity within and between foci [PDF]

open access: yes, 2013
African trypanosomes are unusual among pathogenic protozoa in that they can undergo their complete morphological life cycle in the tsetse fly vector with mating as a non-obligatory part of this development.

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

open access: yesFrontiers 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

open access: yesFrontiers 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

open access: yesG3: 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.

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

open access: yesPLoS 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.

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

open access: yesmBio, 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.

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

open access: yesPLoS 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.
