Description from Yeast Genome.org
BY4742 is part of a set of deletion strains derived from S288C in which commonly used selectable marker genes were deleted by design in order to minimize or eliminate homology to the corresponding marker genes in commonly used vectors without significantly affecting adjacent gene expression. The yeast strains were all directly descended from FY2, which is itself a direct descendant of S288C. Variation between BY4742 and S288C is miniscule. BY4742 was used as a parent strain for the international systematic Saccharomyces cerevisiae gene disruption project.
