Disentangling genetic and epigenetic determinants of ultrafast adaptation The YJL185C, YLR376C and YJR129C genes of Saccharomyces cerevisiae are probably involved in regulation of the glyoxylate cycle. The LSH/HELLS homolog Irc5 contributes to cohesin association with chromatin in yeast Arsenic and antimony transporters in eukaryotes Yeast cell death during DNA damage arrest is independent of caspase or reactive oxygen species. How Saccharomyces cerevisiae copes with toxic metals and metalloids. Different sensitivities of mutants and chimeric forms of human muscle and liver fructose-1,6-bisphosphatases towards AMP. The Swi2-Snf2-like protein Uls1 is involved in replication stress response. New insights into cohesin loading. Transmembrane topology of the arsenite permease Acr3 from Saccharomyces cerevisiae. Mitogen-activated protein kinase Hog1 mediates adaptation to G1 checkpoint arrest during arsenite and hyperosmotic stress. The mitogen-activated protein kinase Slt2 modulates arsenite transport through the aquaglyceroporin Fps1. Metalloid tolerance based on phytochelatins is not functionally equivalent to the arsenite transporter Acr3p. The genetic characteristics Saccharomyces cerevisiae aci(+) mutants. Swi2/Snf2-like protein Uls1 functions in the Sgs1-dependent pathway of maintenance of rDNA stability and
