Fungal mating-type loci
Fungi form one of the most ubiquitous and successful kingdoms of life on Earth. There are more than 100,000 known species of fungi, divided into four phyla — ascomycetes, basidiomycetes, zygomycetes and chytrids — and these have populated a vast array of biological niches, including those that are pathogens of animals (including humans and insects), plants and even other microorganisms. The mor...
متن کاملThe pheromone cell signaling components of the Ustilago a mating-type loci determine intercompatibility between species.
The MAT region of Ustilago hordei, a bipolar barley pathogen, harbors distinct mating functions (a and b loci). Here, we show that the b locus is essential for mating and pathogenicity, and can induce pathogenicity when introduced into a strain carrying a b locus of opposite specificity. Transformation experiments using components of the a1 locus and analysis of resulting dual mating phenotypes...
متن کاملRegulation of mating and pathogenic development in Ustilago maydis.
The plant pathogenic fungus Ustilago maydis induces disease only in its dikaryotic stage that is generated after mating. This process involves coordinated cAMP and mitogen-activated protein kinase signalling to regulate transcriptional as well as morphological responses. Among the induced products is the key regulator for pathogenic development. Recent advances identified crucial nodes that int...
متن کاملSilent Mating-Type Loci in Fission Yeast
In Schizosaccharomyces Pombe the mating-type information is stored at two transcriptionally silent loci (mat2 and mat3). The region between these sites ( K region) is inert for meiotic crossing over. The mating-type genes (M or P) are expressed only when present at a third, active locus (matl). We have earlier shown that the positional regulation of P genes is based on repression at the silent ...
متن کاملA suppressor of mating-type locus mutations in Saccharomyces cerevisiae: evidence for and identification of cryptic mating-type loci.
A mutation has been identified that suppresses the mating and sporulation defects of all mutations in the mating-type loci of S. cerevisiae. This suppressor, sir1-1, restores mating ability to mat alpha 1 and mat alpha 2 mutants and restores sporulation ability to mat alpha 2 and mata1 mutants. MATa sir1-1 strains exhibit a polar budding pattern and have reduced sensitivity to alpha-factor, bot...
