Basidiomycetes Life Cycle at Life

Basidiomycetes Life Cycle. The lifecycle of basidiomycetes includes sexual and asexual reproduction (figure 2). In general, the life cycle involves the fusion of hyphae from two individuals, forming a mycelium that contains haploid nuclei of both individuals.

They are the most evolutionarily advanced fungi, and even their hyphae have a dinstinctly cellular composition. The fused hyphae containing haploid nuclei from two individuals is heterokaryotic. Basidiomycetes are named for their characteristic sexual reproductive structure, the basidium.

The life cycle begins when a haploid spore germinates, dividing mitotically to form a ‘multicellular’ haploid organism (hypha). Turn your attention to the basidiomycete life cycle diagram on the right. What life cycle stage is unique to fungi? The first stage is represented by the primary mycelium or homokaryon (b) which is formed by the germination of a basidiospore (a).
