Pheromones and pheromone receptors are required for proper sexual development in the homothallic ascomycete Sordaria macrospora.
The homothallic, filamentous ascomycete Sordaria macrospora is self-fertile and produces sexual fruiting bodies (perithecia) without a mating partner. Even so, S. macrospora transcriptionally expresses two pheromone-precursor genes (ppg1 and ppg2) and two pheromone-receptor genes (pre1 and pre2). The proteins encoded by these genes are similar to alpha-factor-like and a-factor-like pheromones a...
متن کاملMating-type genes from the homothallic fungus Sordaria macrospora are functionally expressed in a heterothallic ascomycete.
Homokaryons from the homothallic ascomycte Sordaria macrospora are able to enter the sexual pathway and to form fertile fruiting bodies. To analyze the molecular basis of homothallism and to elucidate the role of mating-products during fruiting body development, we cloned and sequenced the entire S. macrospora mating-type locus. Comparison of the Sordaria mating-type locus with mating-type idio...
متن کاملAberrant Tetrads in Sordaria Fimicola* by Lindsay S. Olive
important staphylococcal characteristics such as hemolysin and coagulase production will become available for analysis, either directly through selection or by means of linkage to other selectable markers. More details of the above and the results of further experiments will be reported elsewhere. Summary.-Genetic transduction by staphylococcal bacteriophage has been demonstrated. About one pha...
متن کاملRevisiting the Life Cycle of Dung Fungi, Including Sordaria fimicola
Dung fungi, such as Sordaria fimicola, generally reproduce sexually with ascospores discharged from mammalian dung after passage through herbivores. Their life cycle is thought to be obligate to dung, and thus their ascospores in Quaternary sediments have been interpreted as evidence of past mammalian herbivore activity. Reports of dung fungi as endophytes would seem to challenge the view that ...
متن کاملProgrammed ascospore death in the homothallic ascomycete Coniochaeta tetraspora.
Immature asci of Coniochaeta tetraspora originally contain eight uninucleate ascospores. Two ascospore pairs in each ascus survive and mature, and two die and degenerate. Arrangement of the two ascospore types in individual linear asci is what would be expected if death is controlled by a chromosomal gene segregating at the second meiotic division in about 50% of asci. Cultures originating from...
