Dynamics of Salt Tolerance: Molecular Perspectives

2018
Plant being sessile has to face many environmental stresses and develop physiological and biochemical mechanisms to withstand those stresses. Salinity is one of the major stresses that affects the plant growth and imposes direct impact on productivity and yield. The lack of good-quality irrigation water is forcing farmers to use alternative or degraded

Physiological and molecular mechanisms of plant salt tolerance

Photosynthesis Research, 2013
Salt tolerance is an important economic trait for crops growing in both irrigated fields and marginal lands. The plant kingdom contains plant species that possess highly distinctive capacities for salt tolerance as a result of evolutionary adaptation to their environments. Yet, the cellular mechanisms contributing to salt tolerance seem to be conserved

Bile Salt Transporters: Molecular Characterization, Function, and Regulation

Physiological Reviews, 2003
Molecular medicine has led to rapid advances in the characterization of hepatobiliary transport systems that determine the uptake and excretion of bile salts and other biliary constituents in the liver and extrahepatic tissues. The bile salt pool undergoes an enterohepatic circulation that is regulated by distinct bile salt transport proteins ...

Molecular motion is solid tropylium salts

Chemical Physics Letters, 1968
Abstract Broad line nuclear magnetic resonance studies have been carried out over the temperature range 77°K to 300°K on a representative series of tropylium compounds. The second moments of the line widths indicate that reorientation of the tropylium ions occurs in these solids.

Effects of molecular diffusion of salt in salt-gradient solar ponds

Applied Energy, 1988
Abstract The effect of molecular diffusion of salt is not only significant for the smoothing process during the pond's establishment, but also for its operation. An analysis is presented to calculate the rate of salt transport within an isothermal liquid column, according to the molecular diffusion process.

Polyelectrolytes in Salt Solutions: Molecular Dynamics Simulations

Macromolecules, 2011
We present results of the molecular dynamics simulations of salt solutions of polyelectrolyte chains with number of monomers N = 300. Polyelectrolyte solutions are modeled as an ensemble of bead–spring chains of charged Lennard-Jones particles with explicit counterions and salt ions.

Molecular orbital calculations on pyrylium salts—II

Tetrahedron, 1970
Abstract In an attempt to resolve an anomaly in the long-wavelength absorption spectra of methoxy-and the corresponding hydroxy-substituted pyrylium salts, the visible spectra of 28 compounds have been measured in 10 solvents with widely varying physical properties.

Molecular interactions in polymeric amido-salt solutions

Polymer Science U.S.S.R., 1984
Abstract Nuclear magnetic resonance, IR spectroscopy and solution calorimetry have been used to investigate solutions of poly- m -phenylene isophthalamide in aprotonic solvents in the presence of various salts. It has been shown that salts capable of existing in the form of ion pairs exert an influence on the solubility of the polymer.

Molecular interactions of acids and salts with polyampholytes

The Journal of Chemical Physics
The Hofmeister series characterizes the ability of salt anions to precipitate polyampholytes/proteins. However, the variation of protein size in the bulk solution of acids and the effect of salts on the same have not been studied well. In this article, the four acids (CH3COOH, HNO3, H2SO4, and HCl) and their effects on the hydrodynamic radius (RH) of ...

Molecular Insights Into Salt Stress Adaptation in Plants

Plant, Cell & Environment
ABSTRACTThe significant rise in soil salinity has had detrimental effects on global agricultural production, negatively impacting overall plant health and leading to a decline in productivity. As a protective response, plants have developed diverse regulatory mechanisms to counteract these adverse conditions.
