SK1 is a rapid and synchronously sporulating diploid, widely used for studying the genetics and molecular biology of meiosis and sporulation. SK1 was constructed by Kane and Roth in the early 1970s as part of their work studying carbohydrate metabolism under sporulation conditions. The genome of SK1 is less similar to S288C - about 4 times more divergent - than that of W303. SK1 is better adapted to respiration, which may account, in part, for its more efficient and synchronous sporulation compared to other strains.
Genome sequence information for a particular strain, including GenBank accession IDs and assembly statistics. The table below lists all contigs included in the genome, listed by GenBank accession, with information regarding where that contig maps to the S288C Reference Genome. Note that only the single best BLAST hit for each contig is shown, based on highest bit score from a pairwise BLAST of the genome against S288C using NCBI’s Genome BLAST tool.
