Fitness differences suppress the number of mating types in evolving isogamous species [PDF]
Sexual reproduction is not always synonymous with the existence of two morphologically different sexes; isogamous species produce sex cells of equal size, typically falling into multiple distinct self-incompatible classes, termed mating types.

Conditioning on parental mating types can reduce necessary assumptions for Mendelian randomization [PDF]
Mendelian randomization (MR) has become a common tool used in epidemiological studies. However, when confounding variables are correlated with the instrumental variable (in this case, a genetic/variant/marker), the estimation can remain biased even with ...

Multiplex polymerase chain reaction as an improved method for screening Histoplasma capsulatum mating types [PDF]
Histoplasmosis is a systemic mycosis infection caused by Histoplasma capsulatum, a heterothallic ascomycete. The sexual reproduction of this fungus is regulated by the mating type (MAT1) locus that contains MAT1-1 and MAT1-2 idiomorphs, which were ...

Phylogenetic Analysis of Species Using Mating Type Genes and Distribution of Mating Types in Iran [PDF]
Phaeosphaeria species are pathogenic on wheat, barley and a wide range of wild grasses. To analyze mating type loci of the Phaeosphaeria species and investigate mating type distribution in Iran, we sequenced mating type loci of 273 Phaeosphaeria isolates

Selecting one of several mating types through gene segment joining and deletion in Tetrahymena thermophila. [PDF]
The unicellular eukaryote Tetrahymena thermophila has seven mating types. Cells can mate only when they recognize cells of a different mating type as non-self. As a ciliate, Tetrahymena separates its germline and soma into two nuclei.

Invasion and Extinction Dynamics of Mating Types Under Facultative Sexual Reproduction. [PDF]
International audienceIn sexually reproducing isogamous species, syngamy between gametes is generally not indiscriminate, but rather restricted to occurring between complementary self-incompatible mating types.

Mating-Type Imputation (MTI) Provides an Efficient Tool for the Mating-Type Inference of Tetrapolar Fungi [PDF]
Mating-type identification is fundamental to studies of genetic diversity and genetic breeding in fungi, especially for tetrapolar basidiomycetes, whose mating types are determined by two multiallelic loci, A and B. Traditional mating-type identification

Gamete signalling underlies the evolution of mating types and their number. [PDF]
Predictions about the evolution of sex determination mechanisms have mainly focused on animals and plants, whereas unicellular eukaryotes such as fungi and ciliates have received little attention.

Distribution of the sex-determining gene MID and molecular correspondence of mating types within the isogamous genus Gonium (Volvocales, Chlorophyta). [PDF]
Isogamous organisms lack obvious cytological differences in the gametes of the two complementary mating types. Consequently, it is difficult to ascertain which of the two mating types are homologous when comparing related but sexual isolated strains or ...
