Deletions of a tyrosine tRNA suppressor gene,SUP4-o, are mediated by recombination between short repeated delta sequences inSaccharomyces cerevisiae. The arrangement of the five solo delta sequences that surround theSUP4locus was established by DNA sequence analysis. Seven deletion classes were identified by genomic blotting. DNA sequence analysis also showed that the delta sequences within a 6.5-kilobase region of theSUP4locus were the endpoints of these events. In three of these classes, an adjacent interval surrounded by delta sequences was inverted in concert with the deletion. The frequency of all deletion classes decreased in strains that contained mutations in the recombination and repair geneRAD52. We present two gene conversion mechanisms by which these rearrangements could have been generated. These models may also explain deletions between repeated sequences in other systems.
