Undoubtedly, plant breeders have made considerable achievement in the past few years in improving salinity tolerance in some potential crops using artificial selection and conventional breeding approaches as well as molecular biology approaches, but to a substantial improvement in salinity tolerance in crops is still an important challenge to agricultural scientists. Of the various plant responses to salt stress, the phenomenon of accumulation of organic compounds of low molecular weight collectively known as compatible solutes, has been much focused by the plant scientists in the ...
