Oxidative stress, antioxidants and stress tolerance

Trends in Plant Science, 2002
Traditionally, reactive oxygen intermediates (ROIs) were considered to be toxic by-products of aerobic metabolism, which were disposed of using antioxidants. However, in recent years, it has become apparent that plants actively produce ROIs as signaling molecules to control processes such as programmed cell death, abiotic stress responses, pathogen ...

Chlordiazepoxide and stress tolerance in rats

Pharmacology Biochemistry and Behavior, 1987
Intraperitoneal injections of chlordiazepoxide in rats attenuated the severity of stomach ulcers induced by a single restraint session. However, when the drug was withheld during the last session of a series of repeated restraint treatments, stomach erosions developed in the animals.

SnapShot: Tolerating replication stress

Molecular Cell
Completion of DNA replication relies on the ability of replication forks to traverse various types of DNA damage, actively transcribed regions, and structured DNA. The mechanisms enabling these processes are here referred to as DNA damage tolerance pathways.

Tolerating ER Stress

Science's STKE, 2004
Cells monitor how well synthesis of new proteins in the endoplasmic reticulum (ER) is going, and when stressful conditions cause accumulation of unfolded proteins, the unfolded protein response (UPR) is initiated, which signals for appropriate changes in cellular systems. Ito et al .

Stress Tolerance of Ecosystems

Environmental Conservation, 1976
It is conventionally argued that a stable ecosystem, namely one with high species-diversity and high constancy in physical parameters, is less sensitive to additional stress than a system with varying physical parameters and low species-diversity. By this logic, the Baltic would be more susceptible to additional stress, such as that of pollution, than ...

Breeding for Abiotic Stress Tolerance

1994
The combined effect of all abiotic stress factors is worldwide seen enormous and the deterioration of many soils due to poor farm management is aggravating this. Especially stress factors that reduce and retard growth and development (drought, salinity, acidity, frost, heat, water logging, iron shortage etc.) are very important.

Stress tolerance and metabolic response to stress in Drosophila melanogaster

Heredity, 1998
A potentially important physiological response to stress may be alteration in the gross regulation of energy metabolism. Different genotypes may respond differently to environmental stress, and the variation in these norms of reaction may be of key importance to the maintenance of genetic variation in metabolic traits. In the study reported here, a set

Drought Stress Tolerance

2009
Drought stress severely limits plant growth and productivity. Traditional plant breeding strategies have made significant contributions to the generation of stress-tolerant plants. The problem in setting-up strategies for generating drought stress tolerant plants is the complex multigenic nature of the tolerance mechanisms.

Phenotyping for Abiotic Stress Tolerance in Maize^F

Journal of Integrative Plant Biology, 2012
Abstract image [ Jill E. Cairns ]The ability to quickly develop germplasm having tolerance to several complex polygenic inherited abiotic and biotic stresses combined is critical to the resilience of cropping systems in the face of climate change.
