A TY1 element is inserted in the CYR1 control region of Saccharomyces cerevisiae strain AB320.
Southern blotting using a 5'-proximal probe of the Saccharomyces cerevisiae CYR1 gene has revealed heterogeneity in laboratory strains. It is demonstrated that strain AB320 contains a Ty1 element inserted in the promoter region of CYR1. The Ty1 orientation suggests that transcription of CYR1 is initiated downstream from the insertion region.
