| dc.description.abstract | Using transposon mutagenesis in the haploid Saccharomyces cerevisiae strain W303-1A we have identified genes required for growth in high salt medium, survival of a hypo-osmotic shock and growth at 15 degrees C. Screening 25,000 transposon insertions revealed a total of 61 insertions that caused salt-sensitivity; and those insertions affected 31 genes. Only 12 of those genes were previously known to be required for salt-tolerance. Among the 61 insertions, three caused general osmo-sensitivity. We identified one single insertion mutant in the already-known gene, FPS1, required for survival of hypo-osmotic shock. A total of 31 insertions caused failure to grow at low temperature. Those identified ten different genes, three of which had previously been reported to affect cold-tolerance. Four genes were identified in both the salt and the cold-sensitivity screen. We found several unusual insertion mutations: (1) insertions in or close to essential genes, (2) insertion in an intergenic region and (3) insertions causing stress-sensitivity in W303-1A, while the deletion mutant in BY4741 did not show such a phenotype. Surprisingly, our mutant set and that reported in the large-scale transposon insertion project (TRIPLES, http://ygacmed.yale.edu/triples/triples.htm) only marginally overlap. We discuss some of the features of transposon mutagenesis in light of the availability of the complete set of yeast deletion mutants and we discuss the possible roles of the genes we identified. | por |
