Sex: Deviant Mating in Yeast
Recent comparative genomics and mutational studies of the genes regulating mating and meiosis in fungi provide new insights into not only the variability of the key genes, but also the plasticity of the regulatory circuitry in the evolution of mating systems.
متن کاملYeast Mating: Putting Some Fizz into Fungal Sex?
The mating-competent form of the fungal pathogen Candida albicans is not stable in vitro at the temperature found in its mammalian host where mating occurs. Recent evidence that high levels of CO(2) can stabilize the mating-competent state provides a solution to this puzzle.
متن کاملSynchronous mating in yeast.
Homogeneous a and alpha unbudded yeast cells in logarithmic phase, grown in supplemented minimal medium and isolated by zonal gradient centrifugation, are used for mating. When these cells are resuspended in aerated defined medium, highly synchronous mating rapidly occurs. Within 20 min of incubation at 30 degrees early sexual pairing is evident; extensive agglutination is observed by 60 min, a...
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...
متن کاملMultiple sex pheromones and receptors of a mushroom-producing fungus elicit mating in yeast.
The mushroom-producing fungus Schizophyllum commune has thousands of mating types defined, in part, by numerous lipopeptide pheromones and their G protein-linked receptors. Compatible combinations of pheromones and receptors encoded by different mating types regulate a pathway of sexual development leading to mushroom formation and meiosis. A complex set of pheromone-receptor interactions maxim...
