mating in fungi
Mating in fungi is a complex process governed by mating types. Research on fungal mating has focused on several model species with different behaviour.〔Turgeon B.G. -1998- Application of mating type gene technology to problems in fungal biology. Annual review of Phytopathology. 36:115-137〕 Not all fungi reproduce sexually and many that do are isogamous; the terms "male" and "female" do not apply to many members of the fungal kingdom. Homothallic species are able to mate with themselves, while in heterothallic species only isolates of opposite mating types can mate.
Mating between isogamous fungi may consist only of a transfer of nuclei from one cell to another. Vegetative incompatibility within species often prevent a fungal isolate from mating with another isolate. Isolates of the same incompatibility group do not mate or mating does not lead to successful offspring. High variation has been reported including same chemotype mating, sporophyte to gametophyte mating and biparental transfer of mitochondria.
==Mating in Zygomycota==
A zygomycete hypha grows towards a compatible mate and they both form a bridge, called a progametangia, by joining at the hyphal tips via plasmogamy. A pair of septa forms around the merged tips, enclosing nuclei from both isolates. A second pair of septa forms two adjacent cells, one on each side. These adjacent cells, called suspensors provide structural support. The central cell is destined to become a spore. The nuclei join in a process called karyogamy to form a zygote.
