Detection and characterization of a ring chromosome in the fission yeast Schizosaccharomyces pombe

Nucleic Acids Res. 1992 Nov 25;20(22):5943-5. doi: 10.1093/nar/20.22.5943.


NotI and SfiI genomic restriction maps were used to detect and characterize a ring chromosome II in a Schizosaccharomyces pombe strain with a meiotic defect on chromosome II. The ring chromosome was formed by an intrachromosomal fusion near, or at, the very ends of chromosome II.
