The alternative reference strain SK1 is a rapid and synchronously sporulating diploid constructed by Kane and Roth in the early 1970’s to study carbohydrate metabolism under sporulation conditions. Whereas the reference strain S288C is notorious for being poor at sporulation, SK1 undergoes sporulation readily, and as such has been widely used to study the genetics of sporulation and meiosis.
The genome of SK1, which was temporarily removed from SGD, is now available once again with an updated sequence provided by Scott Keeney from the Sloan Kettering Institute. You can access the updated SK1 sequence for your favorite genes from the Sequence tab, in the Alternative Reference Strains section (example: ECM22 Sequence page). To access the entire SK1 genome sequence, visit the SK1 Strain page.
In addition, we have updated following Sequence and Analysis tools to utilize the latest SK1 sequence:
