Environmental conditions and changes, irrespective of source, cause
a variety of stresses, one of the most prevalent of which is salt
stress. Excess amount of salt in the soil adversely affects plant
growth and development, and impairs production. Nearly 20% of the
world's cultivated area and nearly half of the world's irrigated
lands are affected by salinity. Processes such as seed germination,
seedling growth and vigour, vegetative growth, flowering and fruit
set are adversely affected by high salt concentration, ultimately
causing diminished economic yield and also quality of produce. Most
plants cannot tolerate salt-stress. High salt concentrations
decrease the osmotic potential of soil solution, creating a water
stress in plants and severe ion toxicity. The interactions of salts
with mineral nutrition may result in nutrient imbalances and
deficiencies. The consequence of all these can ultimately lead to
plant death as a result of growth arrest and molecular damage. To
achieve salt-tolerance, the foremost task is either to prevent or
alleviate the damage, or to re-establish homeostatic conditions in
the new stressful environment. Barring a few exceptions, the
conventional breeding techniques have been unsuccessful in
transferring the salt-tolerance trait to the target species. A host
of genes encoding different structural and regulatory proteins have
been used over the past 5-6 years for the development of a range of
abiotic stress-tolerant plants. It has been shown that using
regulatory genes is a more effective approach for developing
stress-tolerant plants. Thus, understanding the molecular basis
will be helpful in developing selection strategies for improving
salinity tolerance. This book will shed light on the effect of salt
stress on plants development, proteomics, genomics, genetic
engineering, and plant adaptations, among other topics. The book
will cover around 25 chapters with contributors from all over the
world.
