Sexual reproduction cycle of basidiomycetes Basidiomycota life cycle Cell cycle of a Dikaryotic basidiomycete Unlike animals and plants which have readily recognizable male and female counterparts, Basidiomycota (except for the Rust ( Pucciniales )) tend to have mutually indistinguishable, compatible haploids which are usually mycelia being ...
Clamp connections are structures unique to the phylum Basidiomycota. Many fungi from this phylum produce spores in basidiocarps (fruiting bodies, or mushrooms), above ground. Though clamp connections are exclusive to this phylum, not all species of Basidiomycota possess these structures.
Diagram showing a basidiomycete mushroom, gill structure, and spore-bearing basidia on the gill margins. A basidium (pl.: basidia) is a microscopic spore-producing structure found on the hymenophore of reproductive bodies of basidiomycete fungi. The presence of basidia is one of the main characteristic features of the group.
The life cycle of the subdivision is dimorphic and it consists of two phases in the life cycle. One saprobic haploid phase and a parasitic ( biotrophic ) dikaryotic phase. The saprobic phase is initiated by the production of haploid yeasts, which fuses with another spore and produce the n+n hyphae which will infect the host.
The vegetative stage encompasses those phases of the life cycle involved with the germination, spread, and survival of the mycelium. Spores germinate under suitable conditions of moisture and temperature, and grow into branching filaments called hyphae , pushing out like roots into the rotting wood.
In the Basidiomycota this is the dominant phase, with most Basidiomycota monokaryons weakly growing and short-lived. Dikaryons shown in a Basidiomycete mitosis cycle The formation of a dikaryon is a plesiomorphic character for the subkingdom Dikarya , which consists of the Basidiomycota and the Ascomycota .
Agaricomycotina is one of three subdivisions of the Basidiomycota (fungi bearing spores on basidia), and represents all of the fungi which form macroscopic fruiting bodies.. Agaricomycotina contains over 30,000 species, [1] divided into three classes: Tremellomycetes, Dacrymycetes, and Agaricomycetes.
