Blocked recombination along the mating-type chromosomes of Neurospora tetrasperma involves both structural heterozygosity and autosomal genes.
The Neurospora tetrasperma mating-type chromosomes have been shown to be structurally heterozygous by reciprocal introgression of these chromosomes between N. tetrasperma and N. crassa. This structural heterozygosity correlates with both a previously described recombination block and cytologically visible unpaired chromosomes at pachytene. Genes on the autosomes are also implicated in blocking ...
متن کاملQuantifying functional heterothallism in the pseudohomothallic ascomycete Neurospora tetrasperma.
Neurospora tetrasperma is a pseudohomothallic filamentous ascomycete that has evolved from heterothallic ancestors. Throughout its life cycle, it is predominantly heterokaryotic for mating type, and thereby self-fertile. However, studies of N. tetrasperma have revealed the occasional production of self-sterile asexual and sexual spores of a single-mating type, indicating that it can be function...
متن کاملEvolution of Synonymous Codon Usage in Neurospora tetrasperma and Neurospora discreta
Neurospora comprises a primary model system for the study of fungal genetics and biology. In spite of this, little is known about genome evolution in Neurospora. For example, the evolution of synonymous codon usage is largely unknown in this genus. In the present investigation, we conducted a comprehensive analysis of synonymous codon usage and its relationship to gene expression and gene lengt...
متن کاملMassive Changes in Genome Architecture Accompany the Transition to Self-Fertility in the Filamentous Fungus Neurospora tetrasperma
A large region of suppressed recombination surrounds the sex-determining locus of the self-fertile fungus Neurospora tetrasperma. This region encompasses nearly one-fifth of the N. tetrasperma genome and suppression of recombination is necessary for self-fertility. The similarity of the N. tetrasperma mating chromosome to plant and animal sex chromosomes and its recent origin (<5 MYA), combined...
متن کاملPseudohomothallism and evolution of the mating-type chromosome in Neurospora tetrasperma.
Ascospores of Neurospora tetrasperma normally contain nuclei of both mating-type idiomorphs (a and A), resulting in self-fertile heterokaryons (a type of sexual reproduction termed pseudohomothallism). Occasional homokaryotic self-sterile strains (either a or A) behave as heterothallics and, in principle, provide N. tetrasperma with a means for facultative outcrossing. This study was conceived ...
