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 ...
Basidiomycota life cycle and morphology The phylum Basidiomycota can be divided into three major lineages: mushrooms , rusts and smuts . Fusion of haploid nuclei ( karyogamy ) occurs in the basidia, club-shaped end cells.
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.
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 .
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.
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 life cycle of the genus Cyathus, which contains both haploid and diploid stages, is typical of taxa in the basidiomycetes that can reproduce both asexually (via vegetative spores), or sexually (with meiosis).
In mycology, the terms teleomorph, anamorph, and holomorph apply to portions of the life cycles of fungi in the phyla Ascomycota and Basidiomycota: Teleomorph: the sexual reproductive stage (morph), typically a fruiting body. Anamorph: an asexual reproductive stage (morph), often mold-like.
