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 کاملstudy on mating types and sensitivity to strobilurin fungicide in fungal wheat pathogen mycosphaerella graminicola
mycosphaerella graminicola, the causal agent of septoria tritici blotch (stb), is a widespread and significant pathogen of wheat. to determine mating types, 89 isolates were collected randomly from wheat fields of khuzestan, east azerbaijan, ardebil, kermanshah and golestan provinces of iran, during 2006-7. dna was extracted based on standard protocols. multiplex pcr was conducted using two pai...
متن کاملInterconversion of Yeast Mating Types
The HO gene promotes interconversion between a and a mating types. As a consequence, homothallic diploid cells are formed by mating between siblings descended from a single crH0 or a HO spore. In order to determine the frequency and pattern of the mating-type switch, we have used a simple technique by which the mating phenotype can be assayed without losing the cell to the mating process itself...
متن کاملSwitching mating types with one arm tied
he mating type (MAT) locus on Saccharomyces cerevisiae chromosome III can recombine with the HMRa locus near the right telomere or the HML ␣ locus near the left telomere of the same chromosome. On page 361, Bressan et al. show that the current mating type of a cell determines the spatial configuration of these three loci in the nucleus, suggesting that the outcome of mating type switching is di...
متن کاملCloning the mating types of the heterothallic fungus Podospora anserina: developmental features of haploid transformants carrying both mating types.
DNAs that encode the mating-type functions (mat+ and mat-) of the filamentous fungus Podospora anserina were cloned with the use of the mating-type A probe from Neurospora crassa. Cloning the full mat information was ascertained through gene replacement experiments. Molecular and functional analyses of haploid transformants carrying both mating types lead to several striking conclusions. Mat+ m...
