Zusammenfassung: | Mating type genes regulate sexual compatibility and sexual reproduction in
fungi. This review focuses on recent molecular analyses of well-characterized
mating systems from representative ascomycete (
Neurospora crassa, Podospora
anserina
) and basidiomycete (
Ustilago maydis, Coprinus cinereus,
Schizophyllum commune
) fungi. These mating systems include many conserved
components, such as gene regulatory polypeptides and pheromone/receptor signal
transduction cascades, as well as conserved processes, like self-nonself
recognition and controlled nuclear migration. The components' structures
and their genetic arrangements in the mating system vary greatly in different
fungi. Although similar components and processes are also found in ascomycete
yeasts (
Saccharomyces cerevisiae
and
Schizosaccharomyces pombe
),
the filamentous systems exhibit properties not encountered in yeast. Mating
type genes act within, and control the development of, spatially differentiated
fruiting bodies. The complex mating systems of basidiomycetes, unlike
ascomycete systems, involve novel one-to-many specificity in both
pheromone-receptor and homeodomain protein interactions. |
