of organisms (as certain fungi or protozoans) incapable of sexual reproduction with one another but capable of such reproduction with members of other strains of the same organism and often capable of behaving as male in respect to one strain and as female in respect to another see minus, ...
For sexual reproduction to occur, mating partner cells must have different MAT alleles. Bipolar systems promote inbreeding, and can lead to the rapid homozygosis of recessive mutations in organisms that are predominantly diploid, such as S. cerevisiae. Fungi with a tetrapolar system, by contrast,...
SummaryFungi capable of sexual reproduction use heterothallic (self-sterile) or homothallic (self-fertile) mating strategies. In most ascomycetes, a single mating type locus, MAT, with two alternative forms (MAT1-1 and MAT1-2) called idiomorphs, controls mating ability. In heterothallic ascom...

MATING TYPE IN FILAMENTOUS FUNGI Mating type genes regulate sexual compatibility and sexual reproduction in fungi. This review focuses on recent molecular analyses of well-characterized ma... JW Kronstad,C Staben - 《Annual Review of Genetics》 被引量: 591发表: 1997年 Molecular Genetics of Mating...
the unusual molecular characteristics of these genes; phylogenetics using MAT; the issues of why some fungi are self-sterile, others self-fertile, and yet others asexual; the long-standing mystery of possible mating type switching in filamentous fungi; and finally the evolutionary origins of pathogen...
INTRODUCTION Homogenic sexual incompatibility in fungi pre- vents self-fertilisation and sexual reproduction between isolates that have identical alleles at the mating type locus. Sexual incompatibility in basidiomycetes can be determined by as many as three loci, while in ascomycetes and oomycetes only...
3.2.1Cloning and analysis of mating-type genes Mating-type genes have been the subject of study in many fungi, including ascomycetes and basidiomycetes. Most plant pathogenic true fungi belong to the ascomycetes and mating-type genes from loculoascomycetes, pyrenomycetes and discomycetes have ...
The use and abuse of pollinators by fungi Some fungi use flower-visiting insects to facilitate sexual reproduction or to disperse spores. These fungi have evolved elaborate techniques, such as flor... B.A. Roy - 《Trends in Ecology & Evolution》 被引量: 111发表: 1994年 Terrestrial vertebrate...
Asexual reproduction is a means of reproduction during which one parent generates genetically identical offspring. Because only one parent is involved, and often each parent makes two offspring, this allows for rapid population growth. However, the population may be vulnerable if it experie...
