摘要: VI. Conclusion The past several years have seen a rapid rise in the number of cloned and characterized mating-type loci from an ever-expanding group of filamentous Ascomycetes. However, the available mating-type gene database still lacks some representatives of functionally or taxonomically important groups. No complete mating-type sequences are available for the Euascomycetes that undergo mating-type switching, or for lichen-forming fungi. The analysis of the evolution of mating types is at the beginning, focusing first on the …
