| Abstract: | Background Comparative sequencing studies among a wide range of taxonomic groups, including fungi, have led to the discovery that reproductive
genes evolve more rapidly than other genes. However, for fungal reproductive genes the question has remained whether the rapid
evolution is a result of stochastic or deterministic processes. The mating-type (mat) genes constitute the master regulators of sexual reproduction in filamentous ascomycetes and here we present a study of
the molecular evolution of the four mat -genes (mat a-1, mat A-1, mat A-2 and mat A-3) of 20 Neurospora taxa. |
