Affymetrix Yeast Genome 2.0 Array (yeast2)
Description
rae1 is an essential gene and encodes one of nuclear pore complex. rae1-167 mutant cells show rapid accumulation of polyA-RNA in the nucleus at 36C followed by protein accumulation, suggesting that accumulated nuclear mRNA influences nucelar cytooplasmic transport.
Publication Title
A systematic genomic screen implicates nucleocytoplasmic transport and membrane growth in nuclear size control.

Description
RSC is a growth essential ATP-dependent chromatin-remodeling complex of Saccharomyces cerevisiae. Nps1/Sth1 is the ATPase subunit of the complex. A temperature-sensitive mutant allele of NPS1, nps1-13 and the null mutation of the RSC2 or RSC7 gene showed growth defect on a medium containing non fermentable carbon source, such as lactate or ethanol-glycerol (YPEG), suggested a possibility that RSC plays a role on mitochondria function.

Description
The SSG1-1 mutation was an allele of the YHR032W gene in Saccharomyces cerevisiae. The SSG1-1 mutants contained higher levels of AdoMet than wild type (WT). SSG1-1 single mutants were shown to have a long lifespan, suggesting that the Ssg1-1 protein might have a role in longevity.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
The CAMTA1 mutant and Col-0 were studied under water and drought condition. The camta1 showed stunted primary root growth under osmotic stress. The expression analysis revealed drought recovery as major indicative pathway along with membrane and chloroplast related protein in camta1 under drought stress. Large number of positively regulated genes were related to osmotic balance, transporters, AP2 and ABA. We used Affymetrix expression analysis to validate the role of CAMTA1 under drought stress.

Description
Saccharomyces cerevisiae is exposed to freeze-thaw stress in commercial processes including frozen dough baking. The cell viability and fermentation activity after freeze-thaw were dramatically decreased due to freeze-thaw injury. Because freeze-thaw injury involves complex phenomena, the mechanisms of it are not fully understood. We attempted to analyze the mechanisms of freeze-thaw injury by indirect gene expression analysis during post-thaw incubation after freeze-thaw treatment using DNA microarray profiling. The results showed that a high frequency of the genes involved in the homeostasis of metal ions were up-regulated depending on the freezing period. The phenotype of the deletion mutants of the up-regulated genes extracted by indirect gene expression analysis was assessed. The deletion strains of the MAC1 and CTR1 genes involved in copper ion homeostasis exhibited freeze-thaw sensitivity, suggesting that copper ion homeostasis is required for freeze-thaw tolerance. Supplementation with copper ions during post-thaw incubation increased intracellular superoxide dismutase activity. Inverse correlated with intracellular superoxide dismutase activity, intracellular levels of reactive oxygen species were decreased. Moreover, cell viability increased by supplementation with copper ions under specific assessment conditions. This study suggested that insufficiency of copper ion homeostasis may be one of the causes of freeze-thaw injury.
