We report here the construction of six deletion mutants and the analysis of their basic phenotype. Deletion cassettes containing the KanMX4 marker module and long flanking regions homologous to the target locus were constructed for each of the six open reading-frames (ORFs YDL088c, YDL087c, YDL086w,

✦ Synopsis
As a part of the EUROFAN programme, six open reading frames from Saccharomyces cerevisiae (YNL083w, YNL086w, YNL087w, YNL097c, YDL100c and YOR086c) were disrupted in two genetic backgrounds, FY1679 and W303. Individual deletions in diploid strains and tetrad analysis of heterozygous deletants revealed that none of them is essential. Basic phenotypic analysis did not reveal any significant difference between the parental and mutant strains. Although YNL087w and YOR086c are 55% identical, the double disruptant also behaves the same as the parental cells. Ydl100p seems to be involved in metal detoxification, the phenotype of the null mutants being enhanced when the assays are performed at 37 C.

We describe here the construction of six deletion mutants and their basic phenotypic analysis in three different backgrounds. The six genes were disrupted in three diploid strains (FY1679, W303 and CEN.PK2) by the long flanking homology (LFH) method (Wach, 1996). Transformants were selected as genet
Six open reading frames (ORFs) of unknown function from the left arm of Saccharomyces cerevisiae chromosome XV were deleted in two genetic backgrounds by disruption cassettes with long flanking homology (LFH) , within the frame of the research project EUROFAN. The LFH disruption cassettes, obtained
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, Y
