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.
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.
They are mostly Ustilaginomycetes (phylum Basidiomycota) and comprise seven of the 15 orders of the subphylum. Most described smuts belong to two orders, Ustilaginales and Tilletiales. [1] The smuts are normally grouped with the other basidiomycetes because of their commonalities concerning sexual reproduction. [2]
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 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).
The life cycle of the Nidulariaceae, 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 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 .
