FUNGI AVOID INBREEDING. “Because there are thousands of different mating types, most encounters between isolates in nature will be fertile, and this drives the frequency of outbreeding to >99 %.” https://lnkd.in/dn4azG7 View in LinkedIn

SPECIFICS OF SOME EXOTIC FUNGI. “In many species, both loci are multiallelic, and as a result there are many different mating types. Both loci must differ for productive mating and thus an isolate of A1B1 mating type can mate with an isolate of A2B2 mating type, but not with isolates that are A1B2 or A2B1.” https://lnkd.in/dn4azG7 View in LinkedIn

EXOTIC FUNGI. “In these species there are two loci that lie unlinked on different chromosomes that specify mating type. These are called the A and B MAT loci, and one encodes the homeodomain factors, and the other encodes pheromones and pheromone receptors (which locus encodes which genes depends on the species, because these loci were named historically as they were discovered genetically long before their molecular basis was elucidated).” https://lnkd.in/dn4azG7 View in LinkedIn

HUGE BELL CURVE. “But other fungi have much more exotic sex lives, and have a more complex mating-type determining system in which there are literally thousands and thousands and thousands of different mating types.” https://lnkd.in/dn4azG7 View in LinkedIn

FUNGI POSTER CHILD. “The paradigmatic example is S. cerevisiae in which a relatively small region of the genome, less than a thousand base pairs, expresses in the alternate mating types one or two key cell fate determinants, all of which are transcription factors responsible for orchestrating both haploid cell type specificity (a or α) and the diploid zygote fate (a/α).” https://lnkd.in/dn4azG7 View in LinkedIn

LARGE KINGDOM. “There are an estimated 5 million species of fungi, and maybe more, much remains to be learned about their sexual nature. Many fungi are currently classified as asexual, and yet many fungi long thought to be asexual have been subsequently found to be sexual, or in some cases at least parasexual (i.e. C. albicans).” https://lnkd.in/dn4azG7 View in LinkedIn

THE DIVERSE KINGDOM. “What about fungi? Relatively few fungi have large size dimorphic sex chromosomes, but there are a few well studied examples such as Neurospora tetrasperma, Podospora, and Microbotryum. Most fungi have relatively smaller regions of their genome, called mating-type loci, or MAT for short, that dictate their mating type.” https://lnkd.in/dn4azG7 View in LinkedIn
