Sentences with phrase «osmotic stress»
Osmotic stress refers to a condition where there is an imbalance in the concentration of solutes (substances dissolved in a solution) inside and outside of a living cell. This imbalance can cause water to flow either into or out of the cell, which can be harmful and put stress on the cell. Full definition
Osmotic Stress Induces Rapid Activation of a Salicylic Acid - Induced Protein Kinase and a Homolog of Protein Kinase ASK1 in Tobacco Cells

Understanding how yeast cope with osmotic stress is useful to understand how human cells respond to medical treatments, but the principles are also applicable to many other fields, including agriculture.
Osmotic stress induces rapid activation of a salicylic acid - induced protein kinase and a homolog of protein kinase ASK1 in tobacco cells.
Goddard and Gray created two environments for the yeast in their lab — one containing relatively little carbon at an uncomfortably hot 37 °C, the other limited for nitrogen instead, at a less stressful 30 °C but with an «osmotic stress» caused by an unusual balance of salts.
The research team identified predictive models of transcription — the first step in gene expression — when the yeast cell is responding to osmotic stress (salt), which greatly affects cell growth.
