polyspore

Polyspore is a term used in mycology to describe a fungal spore that contains multiple viable nuclei. Typically, fungal spores are uninucleate, meaning they contain a single nucleus. However, polyspores exhibit a deviation from this norm, possessing two or more nuclei within a single spore. This characteristic can arise through various mechanisms, including nuclear fusion during spore development or incomplete cytokinesis. The functional significance of polyspore formation is not fully understood and may vary among different fungal species. In some cases, polyspores might contribute to genetic diversity or influence the reproductive success of the fungus. Research into polyspore formation is ongoing to better comprehend its genetic and developmental implications within fungal life cycles.
