Is Evolution of Mating Preferences Inevitable? Random Mating in the Multisex System of Tetrahymena thermophila
Ciliate mating systems are highly diversified, providing unique opportunities to study sexual differentiation and its implications for mating dynamics. Many species of ciliates have multiple (>2) sexes. More sexes may mean more choice and an opportunity for evolution of preferential mating. We asked if the multiple sexes of the ciliate Tetrahymena thermophila mate preferentially among each othe...
متن کاملGenetic map of randomly amplified DNA polymorphisms closely linked to the mating type locus of Tetrahymena thermophila.
We have used the PCR-based randomly amplified polymorphic DNA (RAPD) method to efficiently identify and map DNA polymorphisms in the ciliated protozoan Tetrahymena thermophila. The polymorphisms segregate as Mendelian genetic markers. A targeted screen, using DNA from pooled meiotic segregants, yielded the polymorphisms most closely linked to the mat locus. A total of 10 polymorphisms linked to...
متن کاملGenetic Diversity of Fusarium oxysporum Isolates from Common Bean and Distribution of Mating Type Alleles
Fusarium wilt caused by Fusarium oxysporum Schltdl. f.sp. phaseoli (Fop), is one of the important diseases of the common bean in Iran and many of the bean growing countries. Incidence of the disease has been reported in tropical and semi-tropical regions of the world. This study was carried out to characterize genetic diversity of F. oxysporum isolates from the common bean by vegetative compati...
متن کاملFungal mating-type loci
Fungi form one of the most ubiquitous and successful kingdoms of life on Earth. There are more than 100,000 known species of fungi, divided into four phyla — ascomycetes, basidiomycetes, zygomycetes and chytrids — and these have populated a vast array of biological niches, including those that are pathogens of animals (including humans and insects), plants and even other microorganisms. The mor...
متن کاملYeast Mating Type
Saccharomyces cerevisiae, baker’s yeast, can exist in either a haploid (1n) or a diploid (2n) state. Haploids express one of two mating types, a or a (alpha). Haploids of either mating type are capable of mating with haploids of the opposite mating type in response to the action of mating pheromones. Mating results in fusion of haploid cells, forming an a/a diploid, which is no longer capable o...
