Drought and Salt Stress in Cereals

2015
Abiotic stresses, such as salinity, drought, extreme temperatures, chemical toxicity and oxidative stress represent a grave threat to agriculture dramatically affecting the crop production around the world. Climate changes are projected to have a significant impact on temperature and precipitation profiles increasing the incidence and severity of ...

SALT STRESS

2006
Saline water occupies 71% of the Earth area. It is thought that even a quarter of the whole pedosphere is affected by salts (Glenn and O'Leary, 1985), amounting to 950 x 106 ha (Flowers and Yeo, 1995), while 23 % of the 1.5 x 109 ha cultivated land is considered as saline (Rhoades and Loveday, 1990).

Root hydraulics in salt-stressed wheat

Functional Plant Biology, 2013
The aim of the present study was to test whether salinity, which can impact through its osmotic stress component on the ability of plants to take up water, affects root water transport properties (hydraulic conductivity) in bread wheat (Triticum aestivum L). Hydroponically grown plants were exposed to 100 mM NaCl when they were 10–11 days old.

Stress, Endogenous Opioids and Salt Intake

Appetite, 1984
The effect of stress on NaCl intake was examined in mice given a choice of water and 1.5% NaCl to drink. Immobilization of mice for 15-min and 24-h food deprivation resulted in a 2.5- and 5-fold increases in NaCl intake, respectively, without affecting water intake.

Phosphorus translocation in salt-stressed cotton

Physiologia Plantarum, 1991
The effect of salinity on plants has usually been studied at high inorganic P concentration ([Pi]) in the nutrient solution, and salinity × Pi interactions have been examined at much higher [Pi] than found in soil solutions. Short‐term 32Pi experiments were carried out to study the effect of salinity (150 mM NaCl) on phosphorus translocation in cotton ...

Spermine accumulation under salt stress

Journal of Plant Physiology, 2004
Polyamines have long been recognized to be linked to stress situations, and it is generally accepted that they have protective characteristics. However, little is known about their physiological relevance in plants subjected to long-term salt stress.

Metabolic fingerprinting of salt-stressed tomatoes

Phytochemistry, 2003
The aim of this study was to adopt the approach of metabolic fingerprinting through the use of Fourier transform infrared (FT-IR) spectroscopy and chemometrics to study the effect of salinity on tomato fruit. Two varieties of tomato were studied, Edkawy and Simge F1.

Synechocystis and salt stress

Trends in Plant Science, 1999
Allakhverdiev, S.I. et al. (1999) Genetic engineering of the unsaturation of fatty acids in membrane lipids alters the tolerance of Synechocystis to salt stress, Proc. Natl. Acad. Sci. U. S. A. 96, 5862–5867The level of unsaturation of fatty acids in membrane lipids plays a pivotal role in determining whether an organism can adapt to changing ...

Stress and Salt Sensitivity in Primary Hypertension

Current Hypertension Reports, 2015
As the development of hypertension and target organ damage becomes more prevalent, it becomes exceedingly important to determine the underlying mechanisms through which this detrimental development occurs. Specifically, our studies and others have explored mechanisms through which stress elicits a salt-sensitive response in approximately 20-30 % of the

The effects of stress on salt and water balance

Baillière's Clinical Endocrinology and Metabolism, 1987
The effect of 'stress' on salt and water balance is largely determined by intrinsic renal factors supported by a series of inter-related neuro-humoral mechanisms which serve to enhance salt and water reabsorption and to maintain arterial pressure.
