Abstract excerpt
As industrial shochu yeast is a diploid strain, obtaining a strain with mutations in both allelic genes was considered difficult. We investigated a method for disrupting two copies of a homozygous gene with a single transformation. We designed a disruption cassette containing an intact LYS5 flanked by nonfunctional ura3 gene fragments divided into the 5'- and 3'-regions. These fragments had overlapping sequences...
