Neurospora crassa a mating-type region

摘要: Abstract The a mating-type region of Neurospora crassa controls several major events in both the sexual and asexual phases fungal life cycle. This 3235-base-pair DNA segment is not homologous to comparable genetic A mating type. The unique regions are bordered by nearly identical sequences. contains at least two functional segments. One encodes perithecium maturation function that dependent on second for phenotypic expression. spliced mRNA specifies mt a-1 polypeptide. polypeptide appears be responsible vegetative incompatibility, identity, induction. transcript produced vegetatively under conditions induce differentiation. amino-terminal half shorter Schizosaccharomyces pombe mat-Mc homology properties mutants suggest may primarily functions, while distal required incompatibility.
