We have disrupted seven open reading frames (ORFs) located in the left arm of chromosome XV of the yeast Saccharomyces cerevisiae. These ORFs, previously discovered by our laboratory during the programme of systematic sequencing of the yeast genome, are YOL152w, YOL151w, YOL149w, YOL130w, YOL128c, YOL125w and YOL124c. In most cases, the short flanking homology (SFH) replacement technique has been used. The mutants were analysed for different phenotypic tests. Disruption of YOL130w (also known as ALR1) produced a lethal phenotype, despite the presence of a highly similar gene in the yeast genome (ALR2/YFL050C). Disruption of YOL149w (also known as DCP1, and encoding an mRNA decapping enzyme) results in lethality in the FY1679 background, although it allows slow growth in the CEN.PK141 background. Disruption of the remaining ORFs did not result in readily detectable phenotypic changes.
