Five deletions, constructedin vitro, have been incorporated into theSaccharomyces Cerevisiae GAL7-GAL10-GAL1gene cluster on chromosome II. These deletions permit unambiguous assignment of genetic function to each of the previously identified transcribed regions. TheGAL7andGAL10genes are transcribed right to left while theGAL1gene is transcribed left to right. A deletion of the divergently transcribed region betweenGAL10andGAL1including the sequences homologous to the 5′ ends of all transcripts for both of these genes results in aGAL7+,gal10−,gal1−genotype. This result suggests that each of these three genes can be transcribed from separate promoter regions. A yeast strain, containing therna1-1temperature-sensitive mutation, at non-permissive temperatures accumulates a large RNA containing bothGAL7andGAL10sequences, a small RNA containingGAL7sequences and at least three larger RNAs containingGAL1sequences. Deletion of DNA sequences contained within the largerGAL1transcripts but beyond theGAL1(galactokinase) coding sequences results in a strain able to complementgal1−mutants. This result suggests that the larger transcripts may not be obligate precursors to the stableGAL1mRNAs.
