Sodium transport and salt tolerance in plants
Current Opinion in Cell Biology, 2000The ability of plant cells to maintain low cytosolic sodium concentrations is an essential process associated with the ability of plants to grow in high salt concentrations. Recent results have identified pathways for Na(+) entry, and the cloning of vacuolar Na(+)/H(+) antiporters has demonstrated the role of intracellular Na(+) compartmentation in ...

Physiological and molecular mechanisms of plant salt tolerance
Photosynthesis Research, 2013Salt 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

Cellular Mechanisms of Plant Salt Tolerance
2019Salinity is a severe threat to agricultural production of over 80 million ha arable land area globally, especially in irrigated arid and semiarid regions. Understanding how plants cope with salt stress is therefore imperative. As the glycophytes and halophytes have salt tolerance mechanisms occur at the cellular level, understanding cellular mechanisms

Developing salt-tolerant crop plants: challenges and opportunities
Trends in Plant Science, 2005Soil salinity, one of the major abiotic stresses reducing agricultural productivity, affects large terrestrial areas of the world; the need to produce salt-tolerant crops is evident. Two main approaches are being used to improve salt tolerance: (i) the exploitation of natural genetic variations, either through direct selection in stressful environments

Physiological Basis of Salt Tolerance in Plants
1977For most plants, and under most field conditions, osmotic effects of salinity greatly predominate in restricting growth and yields. In certain cases, however, specific ion effects may be decisive. These may involve either nutrition, as in calcium deficiency in some lettuce varieties, tomato, and bell peppers, or direct toxicity (chloride or sodium ...

Engineering salt tolerance in crop plants
Trends in Plant Science, 2001Environmental stress caused by salinity is a serious factor limiting the productivity of agricultural crops, which are predominantly sensitive to the presence of high concentrations of salts in the soil. Although drainage and the supply of high quality water can solve the problem, these measures are extremely costly and not applicable in extensive ...

Plant Growth‐Promoting Bacteria Associated With Some Salt‐Tolerant Plants
Journal of Basic MicrobiologyABSTRACTGiven the benefits of bacteria associated with the rhizosphere and phytoplane of halophytes, this research focused on examining the plant growth‐promoting characteristics of bacteria isolated from Cressa cretica, Suaeda aegyptiaca, and Alhagi graecorum. From the 33 isolates tested, 9 exhibited plant growth‐promoting traits.

Selection of Salt-Tolerant Plants Using Tissue Culture
1980Plants in nature have evolved a number of adaptive mechanisms to cope with the presence of salt in their environment. The most significant of these mechanisms entails actual tolerance by the plant of high levels of salt within the tissue. This “true tolerance” has been found to provide the greatest tolerance of salt, and is characteristic of most ...

Genetic Methods to Breed Salt Tolerance in Plants
1980Increasing demands for plant products for food, chemicals and energy will require that many of the arid and semi-arid regions of the world be used for crop production. Soil salinity is a perennial problem in arid and semi-arid areas. Crops grown in these areas are quite often irrigated and irrigation frequently compounds difficulties with soil salinity.
