TheSUCgenes (SUC1-SUC7) of Saccharomyces are a family of genes that are dispersed in the yeast genome. ASUC+allele at any locus confers the ability to produce the enzyme invertase and, thus, to ferment sucrose. Most yeast strains do not carrySUC+alleles at all possibleSUCloci. We have investigated the naturally occurring negative (suc0) alleles present atSUCloci with the aim of distinguishing between two possible models for the structure ofsuc0alleles: (1)suc0alleles correspond to a simple absence ofSUCgenetic information; (2)suc0alleles are "silent"SUCgenes that either produce a defective product or are not expressed. To facilitate these studies, sucrose-nonfermenting strains were constructed that are congenic toS. cerevisiaestrain S288C (SUC2+), but carry at theSUC2locus the naturally occurring negative allele,suc20, of strain FL100 (Lacroute 1968). These strains were used to study the genetic properties of thesuc20allele of FL100 and thesuc0alleles (suc10, suc30, etc.) of S288C. Thesuc20allele was shown to revert to an active Suc+state and to provide functional information at three points in theSUC2gene in recombination experiments; thissuc20gene thus appears to be a "silent" gene. Similar tests for silentSUCgenes in S288C (corresponding to loci other thanSUC2) failed to reveal any additional silent genes.
