Extrachromosomal DNA Elements in the Nucleus of Dictyostelium Discoideum

  • Keith L. Williams
Part of the Basic Life Sciences book series (BLSC, volume 40)


Plasmids have long been recognized in the kingdoms of bacteria and archaebacteria (17), while the existence of eukaryote plasmids has been realized only recently. There is one well-characterized nuclear plasmid, the 2-micron circle in the yeast Saccharomyces cerevisiae (10). A number of other plasmids, often associated with mitochondria, have been reported in a variety of eukaryotes (18). The existence of this symposium indicates substantial interest in extrachromosomal elements in simple eukaryotes. I shall summarize what we know of nuclear extrachromosomal elements in a particular ameboid eukaryote, the cellular slime mold Dictyostelium discoideum.
