Why fungi don't have plasmids?

Fungi typically do not possess plasmids because they have a different cellular organization compared to bacteria, where plasmids are commonly found. Fungi are eukaryotic organisms with a complex cellular structure that includes a defined nucleus and organelles, while plasmids are circular DNA molecules primarily associated with prokaryotic cells. Eukaryotic cells, including fungi, usually contain linear chromosomes and utilize mechanisms such as sexual reproduction and genetic recombination for genetic variation. Additionally, while some yeast species can harbor plasmid-like elements, these are not as prevalent or functionally significant as in bacteria.
