Sigma1278b is widely used laboratory strain, and a systematic deletion collection hasbeen constructed in this strain background. There are 75 genes in Sigma1278b that are absent from S288C. Some non-S288C regions in W303 are also present in Sigma1278b, which exhibits six times the rate of sequence divergence to S288C as seen in W303. Sigma1278b is identical toS288C at less than half its genome.
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.
