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 ...
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. Shortly after formation of the diploid cell, meiosis occurs and the resulting four haploid nuclei migrate into four, usually external cells called basidiospores .
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. These bodies are also called tertiary mycelia, which are highly coiled versions of secondary mycelia.
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.
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]
In general for fungi there are two main types of sexual reproduction: homothallism, when mating occurs within a single individual, or in other words each individual is self-fertile; and heterothallism, when hyphae from a single individual are self-sterile and need to interact with another compatible individual for mating to take place ...
A basidium-producing organ; the fruiting body of Basidiomycota. [44] Basidiomycota A Lactarius indigo, a milk-cap mushroom and basidiomycete. Basidiomycetes. A phylum of fungi. Generally defined by sexual reproduction via basidiospores formed from a basidium, although a few purely anamorphic basidiomycetes exist.
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.
