(Submitter supplied) The ability of the yeast Saccharomyces cerevisiae to convert glucose, even in the presence of oxygen, via glycolysis and the fermentative pathway to ethanol has played an important role in its domestication. Despite the extensive knowledge on these pathways in S. cerevisiae, relatively little is known about these pathways in other industrially-relevant Saccharomyces yeast species. In this study we explore the diversity of the glycolytic and fermentative pathways within the Saccharomyces genus using S. more...

(Submitter supplied) As a result of ancestral whole genome and small-scale duplication events, the genome of Saccharomyces cerevisiae’s, and of many eukaryotes, still contain a substantial fraction of duplicated genes. In all investigated organisms, metabolic pathways, and more particularly glycolysis, are specifically enriched for functionally redundant paralogs. In ancestors of the Saccharomyces lineage, the duplication of glycolytic genes is purported to have played an important role leading to S. more...

(Submitter supplied) This study presents a global transcriptional analysis of the cold shock response of Shewanella oneidensis MR-1 after a temperature downshift from 30 to 8 or 15oC based on time-series microarray experiments. More than 700 genes were found to be significantly affected (p < 0.05) upon cold shock challenge, especially at 8oC. The temporal gene expression patterns of the classical cold-shock genes varied and only some of them, most notably so1648 and so2787, were differentially regulated in response to temperature downshift. more...

(Submitter supplied) To investigate low-temperature tolerance of the bacterium, three in-frame gene deletion mutants of VpacspA and VpacspD were constructed using homologous recombination method. When compared to the wild type strain, the growth of ΔVpacspA mutant was strongly repressed at 10 0C, whereas the deletion of VpacspD gene greatly activated the bacterium growth at the low temperature. Transcriptome data revealed that 12.4% of the expressed genes in V. more...

(Submitter supplied) Permafrost soils are extreme environments that exert low-temperature, desiccation and starvation stress on bacteria over thousands to millions of years. To understand how Psychrobacter arcticus 273-4 survived for > 20,000 years in permafrost, transcriptome analysis was performed during growth at 22°C, 17°C, 0°C, and -6°C using a mixed effects ANOVA model. Genes for transcription, translation, energy production and most biosynthetic pathways were down-regulated at low temperatures. more...

(Submitter supplied) Arctic Mesorhizobium strain N33 was isolated from nodules of the Oxytropis arctobia in Canada’s eastern Arctic. This symbiotic bacterium can grow from 0 to 30°C, is one of the best known cold-adapted rhizobia, and can fix nitrogen at ~10°C. Here, the key molecular mechanisms of cold adaptation were investigated by determining changes in transcript profiles when cells were treated under eight different temperature conditions, including both sustained and transient cold treatments compared with cells grown at room temperature.
