The adverse effects of high salt on plants include Na(+) toxicity and hyperosmotic and oxidative stresses. The plasma membrane-localized Na(+)/H(+) antiporter SOS1 functions in the extrusion of toxic Na(+) from cells and is essential for plant salt tolerance. We report here that, under salt or oxidative stress, SOS1 interacts through its predicted cytoplasmic tail with RCD1, a regulator of oxid...

Rice is an important cereal crop responsible for world’s food security. The sensitivity of rice plants toward a range of abiotic stresses is a prime challenge for its overall growth and productivity. Among these, salinity is a major stress which results in a significant loss of global rice yield annually. For finding straightforward and strict future solutions in order to assure the food securi...

In the present study, improvement of salt tolerance in basil (as a salt-sensitive plant) was investigated through silicon (Si) nutrition. Basil plants were subjected to silicon (0, 3 mM) and salinity (0, 50, 100, 150 and 200 mM NaCl) for a duration of one month. Salt stress significantly decreased the biomass of basil. Si supplement (3 mM) resulted in a considerable increase (averagely +135%) i...

Bennett et al. [1] present the phylogenetic distribution of salt-tolerant species on a phylogeny of 2684 grasses in the context of plant breeding for salt-tolerance. Salt-tolerance, they conclude, is an evolutionary labile trait that has evolved a number of times across many lineages; this is at odds with the record of difficulty in breeding salt-tolerant crops. One potential explanation for th...

Salt stress is an important environmental factor that significantly limits crop productivity worldwide. Studies on responses of plants to salt stress in recent years have identified novel signaling pathways and have been at the forefront of plant stress biology and plant biology in general. Thus far, research on salt stress in plants has been focused on cytoplasmic signaling pathways. In this s...

Ethylene has been regarded as a stress hormone to regulate myriad stress responses. Salinity stress is one of the most serious abiotic stresses limiting plant growth and development. But how ethylene signaling is involved in plant response to salt stress is poorly understood. Here we showed that Arabidopsis plants pretreated with ethylene exhibited enhanced tolerance to salt stress. Gain- and l...
