Correction: Quantitative Analysis of Glycerol Accumulation, Glycolysis and Growth under Hyper Osmotic Stress

Quantitative Analysis of Glycerol Accumulation, Glycolysis and Growth under Hyper Osmotic Stress

We provide an integrated dynamic view on a eukaryotic osmolyte system, linking signaling with regulation of gene expression, metabolic control and growth. Adaptation to osmotic changes enables cells to adjust cellular activity and turgor pressure to an altered environment. The yeast Saccharomyces cerevisiae adapts to hyperosmotic stress by activating the HOG signaling cascade, which controls gl...

Text S1 Quantitative analysis of glycerol accumulation, glycolysis and growth under hyperosmotic stress

The roles of osmotic stress and water activity in the inhibition of the growth, glycolysis and glucose phosphotransferase system of Clostridium pasteurianum.

Growth of Clostridium pasteurianum was inhibited in media of high solute content. At equal osmolarities, 'permeant' solutes (glycerol and acetamide) were much less growth-inhibitory than 'non-permeant' solutes (KC1 and xylitol). Glycolysis by washed cell suspensions was inhibited by these solutes in parallel with growth. However, in their inhibition of glucose 6-phosphate dissimilation by perme...

Adaptation of the nematode Caenorhabditis elegans to extreme osmotic stress.

The ability to control osmotic balance is essential for cellular life. Cellular osmotic homeostasis is maintained by accumulation and loss of inorganic ions and organic osmolytes. Although osmoregulation has been studied extensively in many cell types, major gaps exist in our molecular understanding of this essential process. Because of its numerous experimental advantages, the nematode Caenorh...

The Influence of Water-Deficit Stress on Growth, Water Relations and Solute Accumulation in Wild Jujube(Ziziphus lotus)

Wild jujube, Ziziphus lotus, is a multipurpose xerophytic shrub of the Rhamnaceae family widely distributed in arid and semi-arid regions of Tunisia, where it occupies most soil types. The fruit is the edible part of the plant by local population. The reintroduction of this shrub requires the control of its multiplication in response to water shortage. This study aims to evaluate growth and wat...
