We describe the disruption and basic phenotypic analysis of six open reading frames (ORFs) of unknown function located in the left arm of Saccharomyces cerevisiae chromosome VII, namely YGL133w, YGL134w, YGL136c, YGL138c, YGL142c and YGL144c. Disruptions were made using the short ¯anking homology PC

✦ Synopsis
We have constructed S. cerevisiae strains carrying genomic deletions of six ORFs from the left arm of chromosome II (YBL018c, YBL019w, YBL024w, YBL042c, YBL043w and YBL046w) in both FY1679 and W303 backgrounds. We have found that YBL018c is an essential gene in yeast, whereas the other five genes are non-essential. We have developed plasmids carrying deletion cassettes that can be used to delete any of the six genes in S. cerevisiae by transforming to G418-resistance, as well as centromeric plasmids containing the cognate genes.

We constructed replacement cassettes and cloned each ORF into the pRS416 centromeric plasmid. No o
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
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,
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
