Briefly, a single agar plug containing monokaryotic mycelia was placed together with another monokaryon (1 cm apart) on PDA in tubes and incubated at 28C.
Mating tests demonstrated that nine dikaryons in 16 pairings were formed between four monokaryons showing different mating-types of P.
In this study, 20 or more monokaryons were isolated for each Pleurotus species for use in subsequent experiments.
Following the assignment of mating types to all monokaryons isolated from the strains tested, four monokaryotic isolates representing mating types A1B1, A1B2, A2B1, and A2B2 from each Pleurotus species were randomly selected.

Tracking and identification of hyphal fusion and compatible monokaryon type are essential when breeding programmes are being employed such as development of new varieties as well as establishment of newly designated mushroom cross-breeding.
This was done due to the ability of monocaryotic hyphae of some fungi to fuse (anastomose) and exchange genetic material following contact with another monokaryon or dikaryon of the same species (Rayner and Boddy 1988, Ainsworth and Rayner 1989, Beeching et al.
trabeum that have been in use in our lab for some time lose hyphal clamp connections, suggesting reversion to monokaryons and thus putatively less genetically viable (Rayner and Boddy 1988).
Culture morphology: Monokaryon colonies were white of off-white (except for 8021: 13, which was cream-colored), and consistently staurate (i.
Monokaryon cultures are characterized by the following hyphal types: 1) submerged, sclerified hyphal tips of generally acute-triangular shape, with sharp barb-shaped or awl-shaped side branches from a single major hypha; 2) aerial hyphae which act as rhizoids (i.
The hydrophobin protein, Sc3p, is excreted into the growth medium by the wood-rotting fungus Schizophyllum commune when grown as a monokaryon in liquid culture.
