Yeast Mating: Trying Out New Pickup Lines
Mating of Ascomycete fungi involves chemically distinct pheromones; one partner makes a lipid-modified peptide, the other partner a simple peptide. A new study has now found that this inherent asymmetry may not be necessary.
متن کاملSystems in the Act, trying out ACOs.
The law makes ACOs a permanent Medicare option for group practices, physician associations and hospital partnerships. An ACO must commit to a three-year contract to serve an assigned Medicare population of at least 5,000 patients. It must also have a formal legal structure in place to receive and distribute shared savings. However, myriad other important details have yet to be worked out by the...
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 کاملSex: 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.
