WebMany fungi undergo a reproductive phase in which more than one genetically distinct nuclei (from 2 separate mating types) is present within the same cytoplasm. In the Ascomycota and Basidiomycota, this phase is termed "dikaryotic", whereas in other fungal phyla the phase is "heterokaryotic." What is the difference here? WebThe cytoplasm in the individual cells contains one, two or more globose or ellipsoid nuclei which in the somatic portion are small and usually range from 1-2 or 3µ in diameter. They cannot be seen without special techniques. Structurally the nucleus consists of: (i) A central, dense body with a clear area around it. (ii) Chromatin strands, and WebSep 4, 2024 · In basidiomycete fungi, the number of nuclei and their ploidy level per nucleus can vary tremendously among species; however, within species, nuclear number and ploidy levels are traditionally considered fixed in their vegetative hyphae. brmi solution malaysia
